Please Help me Identify This Watch

Hello Omegaforums! I just purchased my first Omega watch and I'm looking to gain some more knowledge on it. My first question is, what model or collection this came form? Did Omegas form the early 1950s not have names? Or is this an unmarked Seamaster or Geneve. Finally i would like to know your opinions on caliber 354. Im new to Omegas and this forum so any info would be appreciated, Thank you!

Hello and welcome to OF!! I am a fellow NOOB, so anything I say should be taken with a grain or maybe a gross of salt, but I am going to attempt and weigh in. First of all, your watch is not a Seamaster or Geneve, they would be marked. There were plain Omega dialed watches. Your watch was cased by Ross, which I believe those with the real knowledge will tell you makes it an American cased movement. You already know that the watch is from the 50's. Your exact date of the movement being produced, but not necessarily shipped can be found using the 14M serial number there on the movement. I think it would be from '54. Your pic of the dial is not clear enough to determine if the dial is original or not, for me at least, but your hands look correct to me. I am not as sure about the crown. The number G2627 is the reference number and you can google that to see others of that reference and check your watch against them. If you have it serviced, make sure not to send it to Omega or an AD, take it to a sympathetic watchmaker who will do only the work necessary and not remove original parts and replace them with new, none original ones. I hope I have helped, have been correct and I see someone else has posted while I was typing this, so let's see how I did.

P.S. Hey, what do you know, going by @JimInOz's post I did alright.......doesn't look like I did it first though. LOL

Interesting, I did not know that some Omegas were cased in NY.

One more question, I know some caliber 354s were chronometer certified, but what were the differences between the ones that were and the ones that weren't? Different parts? Or were they almost exactly the same on the inside?
