Vintage Omega Endlinks 647, 637, 650, 507, 617, 625 - £45 pair

I’ve been going through my parts box and pulled out a range of end links I don’t have any use for. Most of these have accumulated over the last ten years and I don’t know what they came with.
All are used and assume they may need some adjustment to fit.

Terms:
£45 per pair or £25 for single items.
Also happy to trade for a pair or single 532 Endlinks which I’m on the look out for.
Postage at cost. Usually £10 within UK and £15 RoW.
Items in UK.
No returns.

1. Pair of 647 endlinks. 19.5mm. Looks like they fit some kind of c case?

2. Pair of 637 endlinks. 18mm. Possibly for 1168?

3. Single 650 endlink. 20mm.

4. Pair of 507 endlinks. 19mm. Believe they fit Seamaster Cosmics.

5. Single 617 end link. 19mm for 1125 and straight lug Speedmasters.

6. Pair of 625 endlinks. 20mm. For 1170 Soccer Timer and Chronostop?

The 637’s are now sold.

Please note the 625’s are 20mm, not 22mm so I assume they have been filed down.

TTT

Just an FYI, the 647 fit the f300 Connie with the squared off case like the 198.002 with the 1175

Also I believe the 637 are for the oyster style bracelet 1168 and fit Seamaster Cosmics Eg 136.016 but I’m not 100% on this.

Bump

I'm pretty sure the 1168 / 637 combo is paired with the Geneve 165.041, 136.041, etc. The end links for c-case Cosmics like 136.016 don't have the tabs on the back / underside of the end links based on the examples I've seen. Hope that helps potential buyers and GLWS!
