Nice watch yourself!
Mine's a Cal 354 bumper from 1952 with a case ref of 2494-4/2657
It measures around 36.5mm excluding the crown, obviously hardly a 'jumbo' by today's standards but seems to wear a lot bigger than my standard Seamasters
Could be hitting the Private sales forum in a couple of weeks if I can finally make my mind up to let a few watches go to fund a 'new' Omega!
