Mark,
Dave Matthews here from sunny Florida USA. I wanted to personally thank you for this video on the the Omega 2500c as I am a hobbyist that does repairs for a very reduced price for my local customers. I took in this repair believing it was just a mounting screw stuck in the balance. Well it was a mounting screw from the rotor bridge and the hacking spring floating around the movement that stopped it dead. Immediately I went to your awesome videos and diagnosed the problem with the screw stuck in the balance wheel and figured out where that little hacking spring went. Not only was that problem solved but I learned how to install the coaxial balance correctly in this movement which started beating to my relief, after following your instructions. You saved my reputation as a horologist and I my confidence in repairing has grown immensely. To put these videos on RUclips to teach others for free goes beyond being grateful. I thank you for being so generous with your time and knowledge in helping others learn the trade. Thank you so much Mark.
Mark,
You have no idea how much these videos help the rest of us who are interested in learning this information, but have limited avenues from which to learn. Books and tools are available, but to see someone actually doing it can make such a difference. The concept of watch school has all but disappeared and it is you and a very few number of other people on RUclips plus a small number of videos that keep this wonderful craft from vanishing.

This guy is amazing . He makes me want to learn watchmaking .
"Watchmaking" that's another level.
By far the most well done watch repair videos on the internet!
By far indeed. :)
Luxury watches and repair/resto. Two of my favorite things in one.
Enjoy these videos.. would love to see an omega 8500 or 8900 series taken apart.
yeah.. starting from a 2892, coaxial it's a good update in ETA. Equal to 2824 with new balance wheel, C07. I miss work at the Assembly.
Great to see how it's done by a real expert
Thanks a lot! I've successfully serviced my Longines le grande classique by following your video.
I would have to make notes and photograph everything !!!!". Mark is the business for sure. The best !.
I have the exact watch! Nice to see the insides of it... I appreciate it so much more now!
Love the 24 ring tone, I have the same one and thought my phone was ringing upstairs!
Been a very reliable movement for me over the years and the gmt 2893 a2 variant
um trabalho muito delicado e requer muita paciencia otimo video!
Hello Mark, how do remove the crown and stem from this movement? Was it in these videos and I missed it? I just need to install a new dial on my Omega ETA 2892 A2 Seamaster. Thank you very much in advance. I think your channel is the best. Thanks!!!!
+Watch Repair Channel Perfect, thank you Mark..!!!

Are there any Omega watches that have the coaxial escapement in clear view? It seems most of the ones I've seen even with a clear case back it's still hard to see the escapement.
I am fascinated by the details contained in that timepiece!! Apparently that frog too 1:19
Wow .... And I thought that the space shuttle was complicated! Brain surgery would be easier. How do they put these watches together at the factory and how long does it take ??
Love this vid !
2 hours, I was watchmaker assembler in Switzerland.
Very typical of ETA automatics to have such a complicated mechanism for self-winding. There is one in particular I remember having, a remarkable movement of less than 7 lignes diameter, which had a very thick self-winding mechanism with two separate geared one-way clutches to enable bidirectional winding, as well as another clutch which disconnected the mechanism during hand-winding. I have never seen another as complicated as that.
Astonishing skills. I'm guessing you were apprenticed to a master watchmaker.
I hear you mention to sharpen up your tweezers. I have searched but could not find a video of you with tool maintenance. How do you sharpen a tweezer and when? Or when you decide to part and buy a new one? Same for screwdrivers etc. Thank you!
I would love to be able to do what you do. One obstacle is the cost of all the gear you need to do this properly and the other is the years of experience needed to tackle the each job.
always a pleasure to watch your videos
Beautiful movement. I'm curious how do you deal with broken screw heads and or stripped threads? Is this common working on movements? Thx
I was thinking of buying that watch, why have the bearings worn so badly, it cannot be that old? I just need a Co Axial movement for my collection, also seek a watch with spring detente but the only maker has been bought up.
Do I get it right that the third wheel drives the central second wheel as well as the cannon pinion (I'm not sure about the name) that is on the dial side?
i have this watch. is it correct that u can not use the the standard Chronokomparator for testing ?
A pleasure as always. Thanks!
I have one of these and now my mind is blown with what's inside 😳 🤯bonkers
Your videos are extrememely interesting, I have just put my Omega Seamaster Planet Ocean 45XL 2500 Co Axial in for it's first service and now I can see what they actually do, thanks.
My other watch is a Rolex Oysterquartz 19028 (The Egyptian) as it is commonly known if you have the chance to service a Rolex 5055 quartz movement would you video that and upload it?
Hi Mark, I have a SMP 300M mid-size and the rotor makes quite some noise. It doesn’t seem like it’s scraping it’s just spinning quite a lot , wich leaves me to wonder , because I assumed that the 2500 had bi-directional winding. Have some experience with 2824 s and the rotors in those never Spinn that much when already wound. Is that normal for the 2500 series and does the rotor Spinn more easily than the 2825s ?
Could you do a routine service on my Submariner?
How do you get to buy Omega parts ? Or was it before the swatch group closed the gates
Good question. Even more curious is WHO is making Omega repair parts. I’ve twice gotten “Omega” winding stems and new studs for the crown installed that only allow about 1/2 a thread turn to screw the crown down and in both instances the new studs disintegrated after maybe 6 months use and once again, I can’t secure the crown and seal up my Seamaster Professional SMP.
Doesn't it damage the dial when it's upside down and you unscrew the eccentrics because the lume easily crumbles off
Incredible, fantastic video. Thank you
Would love to see a difference between this co axial and today’s
can I ask you please what kind of watch do you wear in normal day to day life?
Hello there, I have an omega Seamaster Chronometer, I am not skilled on repairing watches and I am wondering if you guys can repair it, please let me know and thanks in advance,
Adriano
How did it break? Just wondering.
How do you record those zoomed in videos of the watch dissasembly? Any hints? Would it be possible to dissasemble the watches while watching a live feed from the camera or the device you use while looking at a lcd monitor? I am used to work with both arms while looking on a monitor elsewhere. Can you name the device you use?
How do jewel bearings stay in the movements? Friction fit?
Hi, just a question for anyone that can anser.
Why was the rotor bearing not working? Is that ETA movements being shit? Are the new Omega movements stronger? Does the rotor break this easily on Rolexes?
Hey I recently got a mechanical rotary watch, it's running alittle fast any ideas how to fix this ?
What is your say on the stability of this movement? I heard from people that this movement has issues.
There are 4 versions i beleive a and b had over lubrication issues.c and d are fine.i have a 2010 black smp 300
Are those gears/cogs made of brass, copper, or gold?
thanks a lot for showing us all these details of your service! i got one question - i thought the 2892 A2 has a glucydur balance - hasnt it? iin terms of the form of the balance i 'd say it isnt one, do you have an idea? i am asking cos i ll just get back my Junghans also with a 2892 A2, and i was told it has a glucydur balance, and read so also in internet
This reply is a bit late but yes it does have a glucydur balance wheel. The whole balance complete looks a bit different from your Junghans because it has a Co-Axial Escapement which is an Omega feature they added on.
@@slashdotism well, thanks George......after 5 years isnt soo late..."late" i call "10 years n more " LOL thx
As the owner of a similar watch, can i ask how common this sort of problem is please.
Is it correct to remove all three hands simultaneously?
PS, why didn't you remove the incablocs?
how do you manage remembering the position of each screw? are they all the same?
No finger covers to protect from hand oil?
Hi . I have a seiko5 watch nearly 20 years old and still working well but sometimes slowing down about half an hour a day. It needs to get good service. So let me know how I can send it to you for service?
+Morteza Saremi I don’t do private work. Very sorry.
Fantastic help thanks
I need servicing where you located?
Ughh seeing that dial tugs at my heartstrings a little. I had to sell my 1993 SMP to finance a Speedy Reduced.
Only 2006 to 2012 years had the coaxial added
Very helpful and well presented videos. Thank you. Im reletevly new at watch repsir and one of my biggest frustrations/mistake is tool mark evidence left on parts. Especially if those parts are plated or have fine texture. Overhauling my last caliber I was specificly targeting this partucular problem making sure I dont leave any "signatures". Still... Any advice? Or is it just practice? Thank you again.
orologio eta 2892 _A2 omega
Do you know how I can open the caseback of the latest Seamaster Omega?
Why is the bearing so unique in a 2892?
Do I see a chipped barrel arbor jewel at 8:05?
That watch must had been beaten to hell if it had that much wear on the rotor bearing. It wasn't even that old.
That watch had a previous service performed very poorly they put next to no oil in the train and didn’t oil the escape wheel pivot at all! Not the mention they butchered the screws
Good Job good lesson....thank....Max
How was the bearing damaged? It should not be from normal use
Sometimes things just fail... If it's mechanical it's bound to fail, and even though there may be a mean time between failure of so many thousand hours, there are always those pieces which fall to either side of the bell curve.
Correct, but the movement can't be very old and therefore the probability that the movement would fail is very low. What I am wondering if it was caused by shock, in which other components may be damaged or defective assembly. Damaged caused by lack of lubrication or debris would also take more time to take affect
bluedhands It certainly could be shock or a lack of lube. As much as a rotor spins around it wouldn't take long for a lack of lube to take it's toll on the very few balls that support the oscillating weight. Or perhaps one of the balls was defective new, it shouldn't happen with an Omega but it's possible the vendor supplied part was just outside of tolerance.
How did you adjust the beat error?
May I ask show 2500'D' movement?
Sulmilyeon 2500D & 2500C which are difference? Pls show me! Thank you
hey Mark what is the jewel and what is the work of it in watch ..
swarnim subba jewel is a high frictionless stone used to reduce the wearing in watch components
great memory to fix back the watch. use plastic or bamboo twiser. this is my idea.
Dear sir, I would like to ask you a question. Can we really say that omega is ,,in house ” movement? Isn't Omega owned by Swatch, just like Longines and ETA? Dose Omega have a different place where they produce their movements? Dose that coaxial improvement make Omega's movement In house? Thank you!
you are appreciated. thanks
my friend is a watch maker and trained in swiss , after so many years of repair busineeses , he just quit.
Why?
because of smart watch from Apple and samsung😂😂😂😂
Perfect 👌
Is there a 24 fan there, I'm sure I heard the CTU Ringtone @ the 12:38 mark :)
Really well made videos btw.
Scott McQueen lol - my text message tone.
why the balance wheel is not glucydur ??
Good well done 👍
Nice informative video
my watch chronometer omega works when I make my watch up side down can I have a solution
prem sagar either side of the balance staff( pivots on the balance) might be broken
2500 a, b or c?
C
Video 5 minutes and 45 seconds in what tools you use the screw to be out of you?
A watchmakers screwdriver.

🙌 rejoice!
Another First!
Hat's off!
Great work!
Where’s the can of WD-40?
pleas somthing about eta 201001
Too like your video, how to contact you
wait hold up!
is this a ETA 2892 movement that's been modified??
Yes, in hous Omega 2500 C
Aren't you supposed to wear gloves when touching the movement?
Yeah I was thinking that. Hard to watch.
In reality you should be hardly touching the movement at all. Also you don’t wear gloves. You’ll be sweating a lot if you do that. You wear finger clots.
@@burritolover5082 cots not clots, I'd hate to see that google search lolz
@@jameshisself9324 it auto corrected bud. Aren’t you quite the smart ass. Love that you ignored the whole point I made. “Lolz” tells
Me everything I need to know about you.
He stripping it down and cleaning the parts so probably not necessary as the oils and sweat will be washed off anyway… in part two during reassembly he is wearing finger cots
I hear the ctu text tone!
Remind me not to buy an Omega. Quality looks if'y at best and bearings going on the rotor? It's not like the rotor bearing isn't free and under heavy stress. Some nicely marred screws in this repair too.
That leather plinth needs refinished!
Gosh I thought that this movement was very well decorated like beveled edges and etc...because it’s a premium watch, highly priced and stupidly enough I bought one. Surprisingly to my utter disappointment it’s just another Seiko standard level movement from the line. Why’s the hype? Omega is certainly taking us for a joyride WTF!
They certainly have their similarities, and are both really good companies in the watch market, and meet their own countries chrono standards. Seiko invented quartz movements, and have made great achievements with mechanical movements; But, George Daniels / Omega pioneered the co-axial escapement. The Cal 2500 hasn't been used in most of Omega's watches in a really long time. [Almost?] All of their movements used now are made in house, have around a 60 hour power reserve, and are graded up to 15,000 gauss [15x that of a Rolex Milgauss], meet strict regulations for Chronometer and Master Chronometer certification (as does the ETA 2892.A2), and are made by hand rather than on an assembly line. Just like any luxury item, a person putting the extra time in hand building, and then dressing up the watch is going to create a even greater premium.
ETA??
The movement looks actually quite cheap.
You need a new screw driver
First!
He could definitely EM C a golf match.
