Thanks for the video. You saved me $160 as I don't now - nor ever will - own an automatic watch!
But your channel is great. It's detailed, focused on the affordable watches, and magnificently unpretentious!
Thank you for the support!
You should always have the crown held against the metal prong by the spring clip so that the microphone can hear the vibrations/sound better and give the most accurate reading. If the watch mechanism is removed from the case the crown doesn’t have to be in contact, because the metal body will do the same thing.
Weishi No 1900
AliExpress $169.99 USD + $7.57 shipping (at this moment).
Color LCD Display
480 x 272 pixels or ~4½" x 1½"
Threaded metal inserts for the chassis screws, also for the PCB screws.
Microphone assembly has a preamplifier with a piezo vibration element.
Back of the PCB has a modern design compared to other watch analyzers I have seen
The main CPU is an 8051.
All in all not bad.
The "value" key changes the screen contrast when the grapher is on; when the grapher is paused/stopped, you can enter the menu with the "Menu" key, and then you can manually change the bph and the lift angle. [BTW, the instrument does not automatically recognize a 3600 bph beat rate: maybe, if you manually set the bph, you can graph a quartz watch!] Double check §5 and 6 of the manual, there are some interesting things!
thanks for the tips!
Yeah,
*Manual Selection Range 3600vph/bph (1Hz) to
11880vph/bph (3.3Hz)
*Automatic Detection Range 12000vph/bph (3.33Hz) to 43200vph/bph (12Hz).
Another Note:
Most watches average 18000vph/bph (5Hz) to 21600vph/bph (6Hz).
Possible reference point to know if your Timegrapher remains calibrated.⌚
3600vph/bph is equal to (1Hz) or 1 bps
7200vph/bph is equal to (2Hz) or 2 bps
10800vph/bph is equal to (3Hz) or 3 bps
14400vph/bph is equal to (4Hz) or4 bps
18000vph/bph is equal to (5Hz) or 5 bps
21600vph/bph is equal to (6Hz) or 6 bps
and so on.
the "value" key changes the gain of the microphone.
you can not change the contrast of the screen.
Mine was DOA which is a shame. I thought it seemed well made, but something internal was dead. Power supply was fine. Back to Amazon it goes.
I bought one about 6 months ago and love it, you've probably played around with it enough and found out how sensitive positioning of watch is in the different positions (6) and how much change there is in the different positions. I haven't got around to regulating any of my watches yet, my house is a dust bowl and don't want to contaminate the movement.I'll wait til warmer weather and do it in my garage. I couldn't figure out how to place back ing the styrofoam box so I looked for unboxing vid and found you showed me what I needed. Thanks
Nice! Glad I could help. I need to take care of my dust problem too before I start taking these case backs off.
If I'm not mistaking these time graphers are only meant to be used on manual wind or automatic watch movements.theres separate testers for quartz watches that are much cheaper then a timegrapher.forget what they're called but buddy of mine has them and helped me determine 2 of my Ronda quartz movements took a dump on me and needed replaced.one was a Ronda 715 and other I believe was the 515 gmt movement.actually should be receiving my replacement Ronda movements in mail in next few days so I can get watches back up and going.fun learning how to fix your own watches and how to service automatics and manual winds and its relaxing.gives you more appreciation for your pieces plus it saves you some money in long run assuming your willing to invest about 7 or $800 for some good tools and oils and have the patience to work on watches.for me its a way of calming the nerves after a work week since ammo is too expensive rite now to go target shooting every weekend.lmao
It's a great discipline. I actually just got in my first watch with a Ronda movement. Here's to hoping it doesn't quit on me.
@@the1010watchclub im learning that Rondas are frequently used in a lot of quartz watches that are Swiss made.wish people would use the eta quartz movements but hey I guess we can't have everything we want or wish for.if you just bought the watch and it's brand new you shouldn't have any problems.both the watches that died on me are roughly 10yrs old so guessing they just worn out from age.idk but on a plus side I only paid $35(bought them from a place called Esslingers)for both new movements to replace them with so if it does ever die on you it should be a bit of a comfort that you should be able to get watch running again fairly cheap.im doing work myself so I would have no idea what a watchmaker would charge to replace a quartz movement but I can't see it costing anywhere near what a manual wind or a automatic movement would costs to service.good luck to you and hope you get many years of enjoyment out of your watch.
Quartz testers (proper ones) are much more expensive than these Weishi timegraphers.
I'm not an experienced "watch guy", but I didn't THINK a quartz would do anything on a time grapher. But you did me a service by proving that. (Now, if I can just stop myself from buying one of the fool things.) 😬
Ha! They are definitely fun to play around with
These are not designed for use with quartz watches even if you manually set the beat rate to 3600. The machine is listening for the noise generated by the pallet fork and balance wheel which don't occur in the quartz. It will pick up what looks like random noise. These machines work to the nearest 1 sec per day which is well outside 99% of quartz watch accuracy anyway. So it's quite futile. A proper quartz tester such as Seiko qt2400 which is their latest costs $10,000 new and can measure to 0.001 sec per day. Trouble is they only sell to authorised dealers.
Thanks for the video. You should regulate your watch. You've got the main tool now... 🙂
That's the plan!
Thank you friend for dismember this piece....help me a lot.
Interesting video. I was literally just reading about this exact unit tonight debating on getting one. One article said you need to enter the movements lift angle. Did you have to enter that?
Not for the unboxing but a full video with explanations about the menu, setting the lift angle etc. is coming soon 👍
The lift angle defaults to 52°. It's the most common however the Seiko you used I think has a lift angle of 53°...if my assumption that it uses a 7S26 movement is right. Could be why the amplitude wasn't great or even accurate. The machine uses the lift angle and the tick intervals to compute for the amplitude. However, an incorrect lift angle does not affect the rate or beat error. Have fun with your new toy!
Hi Seiko 7S26 lift angle 52 NH36A 53 standard setting 52 and 12 seconds measurement time NH36A 20 seconds
U have talent, pls keep going.
Thank you for the support!
Thank you for a very interesting video. I've been thinking about buying one myself but then I'm afraid I'm going to be consumed with checking and attempting to regulate all my automatic watches.... 🤔
I have to research "amplitude" and "beat error" to understand these parameters better. If you are able it would be great if you could cover in a future video.
Enjoy your new timegrapher as it is a great addition to your overall equipment arsenal, and will be fun to see what results you get in future watch reviews.
All the best!
Thank you! I definitely will upload another video explaining beat error and amplitude as well as the other functions on the timegrapher
@@the1010watchclub Thank you, that will be great and very much appreciated 👍
@@the1010watchclub where do you don’t amp and lift angle info of a watch?
10:50 made me want to go postal.....but Th,e Force intervened.
Wait what happened at 10:50?
I don't think a Timegrapher is for quartz watches - but even so the instructions said 3600 bph is available in manual mode - not automatic mode.
Does it work if you manually set 3600bph?
Nice toy, even if I’m not sure how useful it really is. I use a G-Shock MB6 watch to see how fast or slow my automatics are. If I were to regulate any of the movements I would get one, but as Marc of Long Island said in one of his previous videos I leave that to guys who know what they’re doing.
I hope it's not too tough, I have an old seiko I got on eBay for like $30 that's running +2 min/day that I'm planning on practicing with first.
@@the1010watchclub I’ve been playing with the idea of getting a practise watch too, and if I do then Weishi here I come 😜
You need at least 260*
Amplitude isn’t great.
Agreed
If you're referring to the Seiko, it wasn't great but I think it wasn't right either. I believe the SKX uses a 7S26 movement and the lift angle for that is 53°. You can't get an accurate amplitude reading if the lift angle parameter is not set correctly.
Japanese movements usually have lower amplitude compared to Swiss.
