Hi everyone,

I would appreciate some help with this third wheel from an Omega 30T2. I bought a non-working watch and the only part damage was the wheel on the left, terrible shape with a missing teeth. I bought a replacement from ebay, and although similar there are small differences in the central pinion that doesn´t allow the central wheel to move freely.

Any help on how to fix this or to buy the correct one it will be greatly appreciated.

The original pinion can be carried to the new wheel using a staking set. That is a somewhat delicate operation, you need to very that the wheel is square to the axis of the pinion.

Is it the height or pivot that is different. As JDM says a delicate operation indeed. If it’s just the pivot that is tight then changing the jewel to fit the pinion is an option, if you have a lathe or a Jacot Pivoting Tool reduce the pivot to fit. If it is the height then as JDM says fit the original pivot to the new wheel or can the jewel be moved this would have to be done with a jeweling tool.

Old pinion has 8 leaves, new one has 9! How can that work? 🙄

Before you do anything: count the teeth number of both wheels and compare! Diameter, too.

Good spot Frank. The only option is to fit the original pinion to the new wheel.

Good point Frank, from now on, I´ll put more attention to that. I noted that the pinions teeth were thinner and a little bit longer, but it didn’t occur to me to count the teeth. I guess I’m just a swapper… : )

I think the pivots are ok, since the train of wheel spins fine down the third wheel, with the second and escape wheels on the bridge.

I guess I must go that route. I do have some stacking tools but only a few punches, so any advice on how to proceed from here it will be greatly appreciated. I haven´t seen any video on YT on this, in case someone could post one.

Thanks for all the advice.....

The tooth modulus is different. 
 

Are you sure this isn’t from a later 26x or 28x caliber? 

No idea... It was sold to me as a 30T2 wheels, but my experience with classic Omegas movements is very limited. I hope someone could help on this.

      Been there. Worn that Tshirt.  'ping'. Hands and knees. Nothing. Nada. 20 minutes? Ha! I found it 7 month later. How? Well, after advice from a member, I invested in a £4 UV light torch.  Hands and knees looking for a 'ping' from a Sekonda, found them both within 30 seconds. UV makes the jewel shine. easy peasy. Could have taken longer. Just lucky on the location of the search. Hope this helps.

      Thanks Dell. I thought about silver soldering. Have never done it but would like to give it a go. Do you think to put flux on the butted joint then run the solder in or to maybe brace it with a piece of scrap spring steel?

      Never and others. Yes, like you I do spend a fair amount of time reading the contents of this forum. I find it better that any other. Clear, lucid, no Prima Donas, and most of all an easy access without adverts. All thanks to Mark. God bless you mate. You give so much to many of us. What if? No Mark? Hypothetically. A forum. I did run a forum for a few years. Really enjoyed it, but became so engrossed that it did affect my health. I gave to to others to run. Not been back. It was very successful and rivalled a number of large paying sites. No adverts, no others but me. I did ask and listen to members comments and it worked well.    Costs Having a domain name, £10 annually.  Register the site with a forum company, free. Build the site using the forum company guide lines, free. It looked and ran almost the same a Mark's. All the same facilities. The cost was only £5 per month, but counted visits (views). If I recall, it was that price for 5,000 views. Each extra 5,000 views increased the price by £2 per month. Success was my own personal undoing. From £5 per month initially, it rose to £60 a month and looked like increasing. This was 10 years ago. I could not afford that, and asked it anyone would like to take over and someone did. I would assume that this is the price that Mark is funding for us all. His return is our continued comments on the internet about his course, and the fact that many of the big names on YouTube mention him as their Tutor. Those of us who have done, and are still using, his course, benefit. In comparison to other courses, I can't believe how cheap it is, and the value is exceptional. It is the structure that gives the value. Long may Mark reign. Ross

      Hi all, total newbie to watchmaking and I've had a bit of a mishap. Just completing level 2 and was doing ok, but I was just on the last part of the reassembly of my ST3620 when the balance end stone shot across the room, just as I was trying to see if I had put the correct amount of oil between it and the balance end, aarrrgh! Been on my hands and knees combing the carpet for 20mins looking for it but to no avail. Does anybody know where I can get a replacement from and what to look for please?? Thanks.
