- Watch Accuracy - What Makes Your Watch Accurate - Federico Talks Watches
In this episode of Federico Talks Watches I discuss watch accuracy and what makes your watch accurate. Really it boils down to a few things, movement tolerances, movement regulation and in how many points your watch movement can be regulated. This can be the difference between your watch running +20 seconds a day or within COSC specifications. Less expensive watches like Seiko can run wonderfully but if they are not regulated as well or have less points of regulation the chance of them running accurately is significantly decreased.

In fact Rolex movements tend not to have a regulator at all. You can only regulate them from the balance screws. Which is of course infernally difficult and should be left to pros. But my advice is, if you want an accurate watch, buy a quartz. If you want a mechanical watch, then don't worry about accuracy.
Or if you want the best of both worlds buy any Seiko Spring Drive model :-)
TimeIsMoney you beat me to it. (Whilst wearing my SBGA103)
4:08 - LOL!
thats exactly what I thought. I dont think it was wholly unintended *wink*. A fight club Tyler Durden "porn in a regular movie" moment right there!
Great vid my Seiko Sumo runs plus 4 sec. a day. I'm pretty satisfied with that. But it kills me to be like 15 sec. fast so like every 3-4 days I reset my watch to perfect time.
I like to think of watch regulation and time keeping like tuning an instrument. An out of tune fender might sound a lot worse than a cheaper instrument that's tuned well but it has the capability of sounding better and staying in tune longer if properly tuned
4:07 that hand sign is so wrong hahaha
Hi Federico,
A watch running slightly fast isn't such an issue for me. But -15 or more seconds a day would be annoying. Because I'm going to sell my Nomos Ahoi, I send it back to Nomos, because of a minor issue. They did a complete overhaul including a re-regulation. Now it's running nicely. Instead of loosing about 10 seconds a day it is running about 2 seconds fast now. Perfect for me!
Best regards,
Claus
Great video, and good to see you back. I was hoping for a broader coverage on accuracy. For example, how magnetic fields affect accuracy and a bit about how Rolex Milgauss uses a Faraday cage and maybe about the Master Chronometer certification by METAS + Omega. Another interesting topic would be about in-house certifications like the Grand Seiko Standard which adds a sixth position in the testing and how it's also a bit tighter at -3/+5 vs COSC's -4/+6. Then, there's the accuracy of quartz, and even more accurate watches that synchronize with GPS or how some watches receive radio signals to sync with atomic clocks to achieve ridiculous levels of accuracy. That would be a much longer video though, so not sure if other people would enjoy it, and perhaps too much to ask. But I really like the photo of the regulator. I also didn't know about the Micro Stella screws on the balance. Thanks
I just had my GMT II serviced and it is +2 per day. It is a 2005 and I purchased it new in 2009. Very happy with it. I also have a Citizen Eco-Drive Radio controlled titanium and it is +-0 every day. I like this one as well. I have others but these are my favorites.
That's some serious "inside baseball" talk. It was presented simply and gave me a lot of knowledge. Especially the five position aspect. Well done.
"Luck of the draw" is a good way to put it. In engineering we talk about tolerance stackup. Every part has its own acceptable tolerance range on manufacture. So when you pull parts out of the bin and assemble them into a unit, the individual part tolerances add up to an overall configuration that can be more or less advantageous, yet still be within the overall tolerances of the finished assembly. Thus a particular Seiko keeping better time than a particular Rolex. The tighter tolerances held on the parts, function, and final assembly the tighter you can control the final product configuration and performance, but there's still a range and some examples in that range will be better than others in the range. Tighter tolerances means more expense. The most expensive pieces are basically handcrafted, with individual part fitting and selection greatly adding to labor and fabrication expense.
I think anyone that follows you would say no apology was needed. You pump out great content and your love for horology is undeniable. Thank you for sharing your knowledge with the rest of us.
No One, that is quite the compliment... Thank you so much!
Don't forget Federico, you can also "regulate" your watch by the position you rest it in eg. crown up, crown down, dial up, dial down etc. Depending on the movement, positional variance when off the wrist can help keep the watch keep good time also!
You are right... I believe I mentioned this in the video...
+Federico I (Federico Talks Watches) oooo apologies! I must've missed it... I had to watch this vid in two parts (due to work) so maybe I must've accidentally skipped that section! :)
No worries man. Glad you enjoyed it though...
Always my friend. Always. Keep up the stellar work! :)
Talk about being a lucky one; I have a Steinhart Ocean One GMT with an ETA 2893-2 movement that's about a year old and it is still running well within COSC Specs. It can gain -4 to +2 seconds per day. Over a two weeks period in can gain as much as 15 seconds. It very seldom loses more than 4 seconds over a week's time. Now that's not to be sneezed at. Lucky me.
the beat rate also affects accuracy, higher beat rates ( 28.800 or more ) tend to have better accuracy in general. Also the amount of mainspring winding affects the speed of the watch, full wound mainspring usually runs slowest , then it gets faster when the amplitude decreases. Automatic watches can be more accurate, because they longer keep the same amount of mainspring winding than hand winding ones, when they where only wound once a day. Temperature also affects the speed/accuryca of the watch.
I wonder what temperature controls there are when regulating watches at the factory if any which might affect the metal contraction/expansion or is that too anal to think about?
Just want to let you know that I appreciate you making videos for us. Thank you, Federico.
As many times as Federico says the word "regulators" and "regulate" I felt like he should've had some Warren G in the background. LOL...
"Regulators!!! Mount up!"
I found in general watches (checked on several ETAs and japan in-house) run slower while being rested on side, and faster while being rested dial up or down flat on the surface. Which is understood as in the 2nd case internal gear wheels are running by standing on the end of the pin - so it is less friction in general across the movement. so when I see watch is getting ahead I rest it on the side for a night to slow it down, or vise versa if it is getting behind. i did not have a large exposure to lot's of watches but this approach will likely work for any mechanical watch - including sealed swatch.
Excellent video as always! Could you make a video talking about Tourbillion watches please and the diferences with price, such Ap tourbilliones with Tag Heuer etc...
You're spot on Federico (as usual!). It is luck of the drawer with regards to accuracy. My Submariner that I've owned for 22 years run around +3/4 secs, my SKX is 2 secs on the wrist, less accurate on the winder and my new Certina DS Action diver is around 9 secs but I'm sure it will get better after some decent wrist time and a chance to get broken in. My wife's Cartier runs 3-4 secs on the wrist but is terrible on the winder. Drops to -20 secs!
I'm sure Fed knows this but some watches will also run differently depending on how close to fully wound they are kept. A watch kept on a winder is not only in a different position (orientation) than it would be laying on the nightstand or in a typical watch box, it is constantly being wound. If a watch is running lets say 15 seconds per day fast, it can probably be improved simply by changing how often and how fully you wind it or what position it lays in if you take it off at night. It takes some effort to figure out each watches "personality" but it can make a difference if you aren't willing to open it up and tweak it.
I love mechanical watches, so to the fact, that my first watch was seiko SKX. I also drain a battery watch in 6 months of ware. I enjoy your videos, very informative. I own a Omega Sea Master, which I have had for 13 years. It's still running accurate. It's only been serviced twice, they are great watches. I am a comieral diver for Lobster in the Bahamas, which has me in the water for 8 hours a day. So I am speaking from experience with the Seiko and Omega, both are awesome dive watches.
Frederico,
Very interesting details about the watch mechanics! Thank you for sharing and in such an approachable way. 😊
Salutations,
JRB
"your video card got corrupted?" Yes you're not a tech guy- but a great watch guy who keeps it real and does not overly gush! I love my Breitling Aerospace, Tissot PR100 dress watch and casio for their accuracy. Considering a Glycene or Sinn 104 but not sure I can deal with the inaccuracy! Great vid thanks Federico!
I may be crazy, but how big of a deal is it to re-set your watch five minutes every few weeks? I can understand if you bought a $30k Patek, but if you picked up a watch for less than a few grand, than a few minutes a month is acceptable.
I agree! I have an oris aquis and it’s pretty damn accurate but after a month or two it may run a minute fast or slow. But I don’t care
Looking fresh as always Federico. The polo, the specs; makes the timepiece look even better!
Thanks Mike... I appreciate it man!
Great Video! Wow, +7,000 subscribers in such a short time: that's what i call a good Job done - Congrats from Austria! Horst Stoeckler
Excellent and very informative. Your explanations and descriptions were easy to follow(not overly technical where it isn't needed).Thank you Federico, a real educational video (and enjoyable as well). Please keep them coming.
I've always wondered about this question. Thank you so much for clarifying the subject. Extremely informative video. Love it.
love the "deer in the headlights" thumbnail. :)
Lol, I thought it was funny too
Great video. Just to let you know that I own two Seiko 5's and they both run quite accurately. I love wearing them.
Hi Frederico, nice video as always. On accuracy, I read a lot of the watch forums etc and find that a lot of people get to hung up on the accuracy of their watch, being not happy if it's 10 seconds out for example. I own a lot of Seikos with the 7S26 movement, and find that on average they are around +/- 10 to 15 seconds which is fine by me, cause they are all consistent. What I wouldn't be happy with is if a watch was + 10 one day - 8 the next + 9 the next - 7 the next, and so on. Consistently +15 is a lot easier to live with than inconsistency.
I agree a watch that is consistently consistent is much better than a watch that is consistently inconsistent....lol
Amazing video Federico thank you for providing so much in-depth information on this subject matter.
Great job !!!
Very well done Federico.
Nice explanation and further evidence that the best time pieces if you just want to tell time are solar powe re d quartz watches.
Great video, Federico! Very informative. Great to hear the technical side of watches.
This video makes me appreciate my watches alot more...Thanks
glad you enjoyed it clifford!
I have an Invicta 8926 with a Seiko NH35A movement and it runs +5 seconds per day average
Very informative, thank you Federico. Also, you have the *worst* luck with technical equipment but good to see it isn't discouraging you.
Thanks Arthur... Trust me it was very discouraging when the file was corrupt, it ruined my evening... But I guess there was nothing to do... Just gotta keep on going I guess...
I enjoyed this talk. It's a subject that I knew nothing about. I'm now better informed.
Are the Rolex “microStellar™ screws” similar to the Omega Spirate™ (whole system)?
Again a great video Frederico!
Thank you sir!
Interesting topic. Thanks.
Great choice of topic brother! Enjoyed and learned something new.
hey Federico, new subscriber here. thanks so much for your content, you're doing a great job. i'm fairly new to the watch game and very interested in learning more about the inner workings of automatic movements, different types of movements, etc. i really appreciate the technical knowledge that you shared in this video and would love to see more like this! keep up the great work!
great delivery of tech information, thankyou, appreciated.
i have all sorts and price ranges of watches but you know the most consistently accurate my f91w casio which cost me nine dollars
still enjoyed the vid learnt a few things
I always learn something new and look forward to each new video
Thank you James, I am glad you can get something out of my content...
Thank you for all you give Frederico. I love your videos, and you seem such a nice fellow too.
Could someone explain the effects of magnetism and accuracy? And wearing it on your wrist versus keeping it in your displaycase? Thank you!
just found your channel today and I'm subscribed👍. also my 1993 Seiko 5 keeps perfect time as long as i wear it. I bought it beat to shit and probably never cleaned but the fact it keeps time has this Gollum precious effect on me.
Hi Federico,I know this video is old but could you explain how a watch gets regulated in 5 positions?
Won't regulating a position mess up the regulations done at the other positions?
All my watches are usually 5 seconds/day fast. Two are exceptions. I regulated my Victorinox Infantry to about 1 second a week. I just got lucky on that one. It's been a while since I've used it so I don't know if it's still that accurate. I also have the Steinhart OT500 that fluctuates between +/- 2 seconds, and it has keep very good time over several months. All my other watches are about +5 seconds/day.
What's your thought on the Seiko 5 and should I buy one?
Great video Frederico! You are a pleasure to learn from. Keep it up.
Love your channel! Can listen to you talking about watch all day. Also got me into watches. Quick question on AP 15400 or 15300. Which one you prefer and why?
Love that Omega. Thanks for the great vid and look forward to the next. Cheers:)
enjoy your content and effort....1 thing Id enjoy is if you showed a close up of your "watch check"....I cant see the watch by you just holding it up....cheers
Nice and useful video for the lovers but not expert of wristwatches like me. Grande Federico continua così !!! ciao dall'Italia .
please rate the desirability of movements as in eta, ronda, miyota and others.
Thanks for the tips Fed! Great work as always brother.
Cheers Mr. Morris!
Your Omega is growing on me! Are you planning on doing youtube fulltime ? Great content.
Excellent content once again!Keep it up, loving the videos
Great video Federico. I always learn something from your videos.
I am glad Cliff!
Great video. I like your more technical view on watches compared to some other channels. Speaking of the Seiko 5, I noticed you can stop the second hand movement by applying the slightest rotation to crown when adjusting the minute hand anti-clockwise. Same with my SKX. Could this damage the movement or is this a feature inherent to non-hackable automatics ? Cheers
Hi Federico , once again great job , but i have just one question could you tell us what can affect the accuracy of a watch , airport doors control , magnetic stuff...... and which one is the worst for our watches , and also if manual winding watches are more or less sensitive than a rotor winding watch , and .... why ?
thanks for your answer
take care :)
Great video, finally figured out what the "spikes" on the balance are! haha. Personal example, I don't have any expensive/Swiss mechanical watches, but between my Orient Mako, Seiko 5 and Invicta, the Invicta has the worst reputation but is by far the most accurate of the three.
Its all the luck of the draw... Doesn't mean its better, just means its better regulated...
Would you agree with me that an automatic watch will keep better time accuracy if the user wears it and is more active such as going walking regularly instead of wearing it and sitting in watching tv.
My Timex automatic is losing about 1/2 hour per day. Is that something I can fix with the plus-minus regulator? Or does the watch need to be cleaned inside? Thanks.
The screws on the balance weight are on freesprung balance wheels, they do not have a regulator do they? They do the same thing, it would be pointless to have both on a watch. Or is it like a "coarse" and a "fine" regulation?
Very interesting and informative as usual. Thank you very much.
Thank you Jose!
Excellentr explanation of whats the regulation is all about, you described technical aspects in plain english for the non connoseur however it will be good to add that in the process of regulating a watch usually the watchmaker makes use of that special machine that shows the deviation from the mean of a particular piece (dont remember the name) which shows a report with dots representing the average deviation from the mean of that watch.
Timegrapher. I've been thinking about buying one. www.wristtimes.com/blog-1/2014/6/24/how-to-use-a-timegrapher
I think you are referring to amplitude
I'm considering now to buy a junghans meister mega. Checks the atomic clock 1440 times per day... so runs within a fraction of a second exact...
I like the mechanical watches... but it's like insisting to have a car with a carburettor and mechanical choke... charming of course...
Great video
Great video and valuable info! Thank you sir
just a question. .I got a rolex.and just wondering while changing the date.does anyone's rolex hands slightly move while changing the date.i got the datjust 2.just wondering.
great informative video federico. Now how about some jazz playing in the background, I'm talking Coltrane or davis. ....
on my Swiss Connect Analytics, it gives an amplitude e.g. 299 degrees. it says -6.1 seconds a day slowing down, face down, and -12 seconds a day face up. Analytics says: your watch is slowing down. Is it time to have my M&B Capeland oiled or serviced? Or is that about average good as it gets. Is 6 to 12 slow in 24 hours a day ok? My most accurate watch is a Dunhill Dhunhillian Eta movement is +2 seconds a day tested face up and face down. I have a newer Ginault Ocean Rover that is gaining 4 to 12 seconds a day depending upon position. What does amplitude signify? thank you
I have a seiko 5 that runs -19 seconds a day, at least I can try to regulate my self without worrying if I'm going to brake it. I like seiko 5's because they're so inexpensive.
If it is running that slow, I would get it serviced, if it were running fast I would simply try to regulate it...
great video. love your channel
Glad you enjoyed it Tony...
Very useful video for a noobie like myself. Thanks Federico! Keep the vids coming
My pleasure... Next video should be sunday!
Hi Federico how is you opinion about automatic victorinox company watches ?? Thanks :)
Hi Federico could tell me please ,would my seiko turtle be regulated for more positions being a dive watch as a diver can be in any direction and or any way up, down etc ,not that l dive but as a watch guy, thought you might know the answer to this question hope you can help me out.
Great video Federico. Keep up the good work! :)
I am glad you got something out of it Venguin
Constructive critic...the video volume is low
Some minor adjustment or positioning of your equipment can improve the end result
Keep the great work Frederico
Keep stunting Federico you're a true inspiration. Bless 🙏🙏🙏🙏
Lol thanks kevin! Much appreciated!
good insight and info.
thumbs up
Cheers B
Most of my watches beat at 21600 bph, but some are chronometers. Does this mean that a 21600 bph chrono is less accurate than a 28800?
Very helpful video! Thanks!
Much appreciated Andrew...
Thank you for this great free video! Never a need to apologize for altruism that misses a day. Fantastic explanation of the LUCK OF THE DRAW nature of automatic watches. I tweeted this out- I’m an immediate fan! /I.A. Schneider/
Another awesome vid Federico, I just have a random question, seeing as you're a Panerai guy, I was looking at purchasing a Panerai Pam 74 but noticed it has been discontinued for some reason, is this watch really that rare because I thought it was the Pam 72 (which is identical minus the movement i believe) that was the limited edition watch. Anyways any feedback would be highly appreciated, thanks.
Screw in and out. With the hand sign. Love it. Federico will cringe when he looks back at this vid.
The Citizen titanium blue dial eco drive is the most accurate watch ever. I wear it now 1.5 month....0.5 second difference with the atomic time...amazing
Hey Federico, what are your thoughts on Invicta watches? Thanks in advance!
Hi Federico,
I just had a quick question for you (or anyone else who can respond) about measuring a watches accuracy. Is it simply an average over a span of time? For example, if I set a watch to match the atomic clock, then a week later, that watch is now 35 seconds behind the atomic clock, is it simply averaged at -5 seconds/day? If not, how is this actually done?
Thanks!!!!
buy a multifunction timegrapher and regulate any watch to + or - 2 sec per day.
Good one my friend!
Cheers Don!
I'm wanting to buy a Carrera Automatic Chronograph Black Dial Stainless Steel Men's WatchItem No. CV2A1R.BA0799. how are they and are they worth money?
Federico, great talk!
Question: how do I measure how many seconds a day my watch is running at? I own a Breitling Navitimer World and I am very interested in measuring this.
You can buy a timegrapher
My seiko 5 runs suprisingly good as well. In a about 2 weeks, it's only about a minute off.
That is pretty damn good...
