I recently inherited an Omega Automatic Seamaster Calendar from my grandfather. I have done about an hour or two of research and can't seem to find much info on this watch. From what I have gathered, it is most likely from the early 1950's and is a "bumper". I have included a few photos, if anyone has any other information it would be greatly appreciated. I would like to know the year and model, as well as any other info possible. I have looked at numerous pictures and can't seem to find another one with the calendar date and hours marked like this one. Also please disregard the wristband as I know that is not authentic. I am currently looking for the correct time period band. Thanks in advance!

 

Thanks for the quick response cicindela. I really appreciate the info as I seek help determining what I have here. You have me headed on the right path now!

All the 2627's I am seeing have the number configuration on 3, 9, 12 rather than the 2, 4, 8, 10, 12 configuration I have. I assume there were different variations?

How difficult is it to remove the back to see the movement inside? I have never opened up a watch before.

Also, where would I be able to buy the leather strap and buckle? Are they hard to find?

This is my first vintage watch, so please forgive my ignorance.

 

Yes, most models had many many different dial variations.

If you haven't done it before, don't try it! Take it to an independent watchmaker/watch repairer. You should also get it serviced/oiled/cleaned (maybe $200), best done at an independent watchmaker, rather than an officila Omega service centre, who will charge a fortune.

Most of us don't bother with genuine Omega bands/buckles. They are quite expensive. You can take the watch to any jeweller/watch shop to get a new leather band. Prices can vary from $30 to $200, depending on whether you go cow, lizard, alligator, koala, elephant, etc. There are some good ebay watch band sellers (keralan is a favourite here, but he only ships tot he US). you cuold also, if you wanted, get an omega buckle that could be put on a non-omega band. once again, heaps on ebay.

 

I am really keen trying on Koala strap ....... A genuine Australia export commodity.
