Hi all, I bought this one recently just to found out that there is a difference of 7 years between case and movement. Otherwise it fits. Omega says that cal. 550 should be in ref. 14905 and it is as well as bridge with cal. and serial is the same so no alteration there and it is a cal. 550 as it has 17 jewels and not 24 as 552 would have. Anyone seen 14905 or other year determined (five digit) case with so late/high serial?
Watch looks fine to me. Serial puts it at late 60's which is consistent with dial, etc. Crown is incorrect but otherwise looks like a nice daily wearer. Enjoy it.
