Omega 1045 / Lemania 5100 Part

Question

I recently acquired an Omega Speedmaster automatic from the 1970's that has the Omega 1045 / Lemania 5100 movement inside.  Long story short- the previous owner tried to service it and made a mess instead.  I've managed to source all the parts I think I need except one for the automatic works- the Stop Spring (part no. 1414).  This looks like a part I may be able to fabricate but if the original is available I would prefer that.  Unfortunately I've come up empty with my usual suppliers.   Cousins is the one one who may have it, but it's Restricted which I suppose means you need to be an Omega authorized technician (which I naturally am not) to purchase.

If anyone has a lead to follow I would be most grateful for your assistance.  This piece is a proper mess right now but I think I'm close to bringing it back from the dead.

Thanks Stuart- I can't imagine why I didn't think to check Watchguy's listing.  I've sent an inquiry to him today.

You’re most welcome! I enjoy the challenge. There’s one here too

One day I will write a list of how to find watch parts!!

Hello @RyMoeller,

I looked up the part using Bestfit MATSYS and, if you come across any of them, these are the only cross references I found that use that spring: Rodania (Lemania 5012) and Tissot 2910.  I just checked Borel, but A/8767 is out of stock.

Thanks J- that's very helpful.  As @rogart63 pointed out- I just discovered that ETA is producing a movement that's based on the 5100 again so I'll try that avenue as well.

I must say, it's a simple spring and a very "common" shape. You can easily fit a similar spring from many other scrap movements (or springs assortment) to that recess in the plate.
Yes and no, it has a sort of raised portion at the business end, that sort of does the business . It's also surprisingly light in force for its size.

      Hi folks , I’m working on the Omega t17 that have a really strange problem, if i wind it to full power it seems to run like crazy with mad reading , but if i wind it ..say 5-7 time it keep the rate better , also the amplitude is almost the same on 5-7 turn and full turn at 290-320 
      i attaches the photo of the read 
      I also noted that the beat rate is expanding and close on the reading too, Balance swings is not even ?
      thanks for the read and answer!

      Hi,
      in order to buy appropriate spares in my attempt to service an Omega 175.0083 (7750)  I need some advice:
      1.
      I've already been suggested to replace MS:
      Barrel is Ok and I'm thinking of buying a new MS and moebius 8217 for barrel lubricating as I don't want to spend money on recommended Kluber 125 grease.
      Should I consider instead buying a barrel complete (assuming Barrel complete (180.1) comes with MS installed) wich supposedly comes prelubricated ?
      2.
      Attached image shows automatic device bridge with evident sign of wear from where, to my understanding, the problem orginated: a screw came off
      I cant find original part. 
      ETA part is different from Omega in that the Omega is larger and partially covers hammer two function and the chronograph cam.
      Beside that and since the watch has no crystal back case I think those parts are perfectly interchangeable.
      Do I need to replace the bridge or are there alternative aproaches to this problem?
      TIA
      Giuseppe

      Hello all,im new at trying to fix watches. This is my third attempt as my previous watches where so rusted internally that it wasnt worth it.But I recently got a Ladies Seamaster Automatic 684, 586.0089 1976 (according to the Omega web portal).
      I was curious if anybody knew what the paint or material that is on the hour markers is??And if it was available somewhere to buy? or is it an obsolete way of face dial design? Since under a loop it has the appearance of sand glued on metal slivers. Can it be that the original paint degraded over the decades?
      Sorry I couldn’t get really up close images.
      Thank you for all the wisdom for this beginner,mario.

      Hello,
      I'm new to this forum that I've followed for a while.
      I began to collect watches, also trying to service them. Not very successful so far, but I'm learning.
      I have to replace a regulator on a balance bridge on Omega Seamaster cal. 286.
      I don't see any screw to remove it , don't want to break anything.
      Any suggestion would be appreciated.
      Kind regards
      Luc
