Hi all,

I am servicing this vintage Omega ladies watch with cal. 511.0452 (cal number engraved at the inner case-back)  and following problem occurred:
There was initially no problem with the watch (dirt, not serviced for looong time) but after clean and reassembly the hand setting was a bit hard. This ended up in a bit of a jump when turned harder.
When I opened the movement again (and removed the dial), I realised that the minute wheel lost about 1/3 of its teeth.

Now my concerns:
- What caused this? Is it possible that when I removed the cannon pinion I actually tightened it by accident? Or could it be insufficient lubrication between the center wheel and the cannon pinion?
- Where do I get replacement parts for this tiny movement? (Cousins doesn't seem to have anything with number 511.0452)
- When I search for the parts, can I just stick to the 511 or do I have to match the part for 511.0452?

I did a little exercise and removed/relubricated the cannon pinion and center wheel and now there I can turn the cannon pinion with tweezers (still too tough but much better).
Pics follow, thanks for your help.

Your mixing up calibre number with model number, the case back engraving is the watch model number not calibre number. Look on the top plate of the movement there should be a omega symbol under that there will be the calibre number

i think it could be cheaper to buy a donor . Minute wheel on cousinsuk cost £25 and tax . A donor you can have for £30 maybe. You saw you did check the cannon pinion . 

by donor you mean a broken 1070 lets say from ebay? yes cannon pinion+minute wheel is £50

      Movement holder made with 3D printer

      By Waggy · Posted

      So here is the new base (v 2.1), I made it so that the base will fit over and swallow the stump of the hand pusher tool (or at least my clone of the tool), I also reduced the OD of the bottom skirt a little as it looked/felt a little large, here are a few pictures and the fake .pdf file which you need to convert to .zip once downloaded.   The cut-out seen on the below image on the bottom of the base should swallow the OD (40 mm, +0.1 mm tolerance) of the stump and the height of the stump 9.5mm (measured to 9.1mm, but rounded to 9.5mm) - let me know if this works for your tool.   Note, I think you may need to print supports for the new internal shelf created?

      Balance spring fell out of regulator pin.

      By HectorLooi · Posted

      Hi Frank, you have dived headlong into the deep end. Hairspring work has to be the scariest thing a newbie has to tackle. Your hairspring appears to be bent and just putting it back into the regulator would not allow the balance to work properly. It might start oscillating but the performance would not be good. The proper thing to do is to unstud the hairspring, remove the hairspring from the balance, reinstall the hairspring on the stud carrier, reshape the endcurve and centre the collet to the balance jewel hole. This challenge would either make you or break you. Hope that you will be able to fix your watch. Welcome to the world of watchmaking.  Watch this video. It think it'll give you an idea of the task ahead. From your 1st photo, I think you have a etachron type stud. Let me see if I can find a video on how to remove it from the arm.

      Have read of the Tech Sheet attached on the balance section page 12. It may be bent but until you reposition it back in the regulator pins you'll never know. Cheers CJ 4R35B_4R36A.pdf

      Balance spring fell out of regulator pin.

      By Hawaiikook808 · Posted

      Aloha All, My Seiko 4R35B movement stopped working today. Upon closer inspection, it looks like the balance spring came out of the regulator pin. This is my first time working on a balance. Any advice on how to get this spring repositioned (back to normal)? I'm pretty sure that while adjusting the beat error on this movement, I must have turned the stud (I didn't even know they turned), and the spring eventually fell out.  Will the spring go back to even spacing when it's back in the pin, or does it look bent? Thanks, Frank

      Good job, that band matches the watch perfectly.
