  1. Cousins did quibble a little to start with, saying my order matched the part supplied. They said their supplier, Bestfit state that there’s no difference in stems between the Omega 23.7 caliber variations. They requested photographic evidence of the movement showing the caliber reference and a side by side photo of the stems to compare. After sending, they agreed that there was a problem and offered the refund on return of the stem at my expense. Oh well, £2.11 to return it for a £20 refund. I shall definitely check the market in future for my more obscure parts. Thanks again. Sent from my iPhone using Tapatalk
  2. Chopin, thank you so much for the advice you gave me a few days ago. The replacement stem arrived from France and it fits perfectly. Cousins have even agreed to a refund! I have now been able to complete my restoration of this old gem and it’s now being enjoyed on my wrist Sent from my iPhone using Tapatalk
  3. Yep, agree. You can carefully wind in by hand without a tool, though there’s a risk of distorting the spring. I’ve done this before I invested in winders too. Sent from my iPad using Tapatalk
  4. Hi Charlie, I have installed a number of mainsprings using this method (as well as a mainspring winder). Providing you ensure the spring within the shim (jiffy-pak) is seated within the barrel before pressing down, you will have no problem. Press firmly around the circumference and it will “click “ into place and the shim will fall away. One word of caution; there are right and left hand wound springs. If you took a photo before removing the old spring, take note of the direction of the spring coil in the centre. Right-hand wound (the most common) are installed with the coloured side of the shim facing up towards you, for left-hand winders, simply flip the shim over. I found this out once by mistake and ended up having to remove the spring and reinstall with a mainspring winder. Sent from my iPad using Tapatalk
  5. Very interesting discussion. In my case I’ll take note for potential future repairs as all these tasks requiring more advanced technical expertise is what I aspire achieve in the future but unfortunately I’m not ready yet at my current skill level. Sent from my iPad using Tapatalk
  6. Thanks for your response. I noticed that the NOS stem I’ve ordered is tap 11 rather than the tap 9 sent from Cousins, and the crown and stem that came with the watch is also tap 11 but the stem was not even long enough to engage the pivot hole, hence the replacement. I generally allow about 2-3mm over on stems that I cut and then finish trimming to size and deburring with a carborundum stone. Great idea about the die plate, thanks. Though I’m developing my skills and getting a good set of tools together, I don’t have any broaching tools and I’m not sure I’d have the confidence to tackle that yet. Perhaps something I could attempt on a scrap plate first once I have purchased the tools. Hopefully it won’t come to that but really appreciate your thoughts on this. Sent from my iPad using Tapatalk
  7. That was one of my initial thoughts. However, the movement was stripped down fully and ultrasonically cleaned. When investigating yesterday, I double-checked that the hole was not obstructed under high magnification. Thanks for your interest, appreciated. Sent from my iPad using Tapatalk
  8. Thanks Chopin. I’ve taken your advice and ordered a NOS item on eBay from France. Fingers crossed. Sent from my iPhone using Tapatalk
  9. I have been working on a lovely old 1924 Omega 23.7 S.T2 gents' wristwatch and have had some limited success in stripping down, servicing and reassembly in that the movement now works and keeps good time. However, on inspecting the parts as I went, I realised that the crown and stem weren't original, explaining why it kept falling out. So I ordered a replacement Omega stem for the exact calibre from Cousins, which arrived today. However, thinking this would be the issue resolved, I was disappointed to find after closer examination of the keyless works, that the pivot shaft end of the stem will not slide home through the pivot shaft hole. I have included photos the best I can to illustrate the problem with some additional photos of the watch for reference. I have been watchmaking as a hobby for about 8 months and this looks like a pretty advanced problem to solve. If anyone has any ideas how I can get the stem engaged in the pivot hole or any other suggestions, and really appreciate hearing from you.

    Is this mainspring ok?

    I’d replace it with a modern alloy spring. It’s old and the fact that it’s not lying flat would be enough for me to replace. It’s also likely that performance will be affected. Sent from my iPad using Tapatalk
  11. Couldn't wait with getting this far. Tricky but did it. Thanks gentlemen!
  12. Bit the bullet and removed the rotor bridge. I think I can see the flat spring hiding further down underneath that centre pinion. I've circled it in red. Just in case anybody's got a pointer to watch out for, I'll leave this one till tomorrow now.
  13. Okay. I have taken the rotor off and the drive wheel and now have what's shown in the photo. So rather than just dive in, when you say rotor bridge, I'm assuming I now need to bite the bullet and remove the two screws holding it on. It just looks quite different to your photo (accepting that it's a different movement). Presumably I'm going to have to remove a number of wheels underneath looking at those pivots?! Apologies for probably ask ing the obvious
  14. Hello, I have been asked to fix a problem with the stem of an Omega Geneve that wasn't engaging to set the hands and wind. Fair enough, I'm becoming a little more experienced now after six months of tinkering and soon identified that the winding pinion had popped out of its housing and fouling the calendar wheel teeth - presumably someone else had removed the stem before! Anyhow, fiddly but I fixed the problem, reassembled, and everything tested out okay (winds, hands set, and calendar quick set works). The problem now is that when I fit the second hand it keeps falling off, though while laid flat face up, the second hand moves around the dial normally. I've added a couple of photos, just in case you can spot anything. I must add that I ordered a set of used replacement hands, thinking that the second hand hole (if that's the term) had become worn and too large for the pinion. However, the replacement hand makes no difference. So am I now correct in looking towards pinion wear that's driving the second hand through the cannon pinion? Am I doing anything obviously wrong that you may be able to provide a tip for. I am using a proper Horotec hand fitting tool in an attempt to press the hand fully home, though afraid to exert much force in case I damage anything. Any help would be greatly appreciated. Thanks, Adam
  15. They seem legitimate. I’m from the UK so not familiar with US associations. But what I would do if you have concerns is contact the Watch & Clock Association yourself for reassurance.
