Wouldn’t the 2209 be correct for 21mm with a strap?
Yes, 2209's are correct
https://omegaforums.net/posts/2261644/Archer ·Since this subject has come up a lot lately, maybe I can explain it using a photo that will help. I'm sure this has been covered before, but here's a photo that illustrates how these spring bars work and relate to each other:
In this case I'm comparing 2207, 2208, and a generic 20 mm spring bar. As you can see the 2208 is the same length as the 20 mm generic bar. The 2207 is actually shorter than the 20 mm bar, but would be what Omega uses for a 20 mm lug width when...
Yes, that's what it says - 2208's with the strap. Why? Who knows...
Thanks for the confirmation. That’s puzzling. The only explanation I can come up with: the OEM strap at the lug end is 5mm in thickness; maybe the technicians thought this was thick enough to prevent loss through wiggle?
Not sure - the only time I would expect to see a "bracelet" length spring bar used on a strap, is when the strap has what I would describe as end link like design characteristics. So instead of just a hole in a leather strap, a harder plastic end link that has limited space to retract the spring bar, like you would see in a steel end link (these are more common on rubber straps I find). It's not that type of strap on this watch from what I see, so again not the normal spring bar I would expect.
