My first vintage Omega

[mamas]

nice piece! the redial looks to be tastefully done. my only concern is that cal. 510 was never used in vintage semasters..are you sure that is what it has inside? as if it is then this unfortunately would be a frankenwatch :( :(
you can cross check on the omega vintage website.. register, go to advanced search and enetr 510 calibre number there and you will see only 3 models that used this mechanism and none of them where semasters.
