Hello,
This was my grandfather's watch, recently given to me by my father.
I've done some digging around here today so I have a bit of context, but curious if anyone can provide any insight on what I've got here.
So far only external photos, I have a case-back opener tool on the way from Amazon, but until then this is what I've got.
Was likely purchased in New Jersey (maybe New York) in the 50s or 60s...?
Case and back are both stamped "14k gold"
Spiedel band certainly not original.
No "Swiss" or "Swiss made" markings visible on the dial. Stem is signed.

Thanks!

Nice watch and welcome to the forum!
It definitely looks like its from the late 1950s. These watches are simply referred to as "automatics".
The crystal tension ring may be covering the "Swiss" or "Swiss Made" text.
Once you get the case-back open you should find its ref number, and on the movement you should see an 8 digit number which will tell you when it was made.

Good luck with it.👍

If you can't wait for the Amazon tool: balled-up duct tape with the sticky on the outside. A golf-ball size sometimes gives enough grip to turn the caseback, and there's zero risk of damage.

Hi mate.

You have an American produced case there, so there will not be a Swiss reference number in the caseback.

I love the pairing with the Speidel band 😁

Many of those Amazon watch openers fail on the first try, scratching your watch in the process. Up to you if you feel curious enough to risk it. The tape trick noted above might work, same with a rubber ball or a dog’s Kong toy (they work famously). Your watch likely needs a service anyway, and your watchmaker can tell you all you want to know

PS, very cool to have your grandfather’s watch!

The Kong dog toy must be cleaned heavily before using on a watch.

A brand new one is impregnated with a mould release agent, some slippery silicone stuff that defeats the purpose.

A "used" one will be covered in dog slobber with the same effect on friction/sticktion that the new one has.

Top rack of the dishwasher will solve the problem.

👍 Rubbing alcohol will take off some of the coating on the business end of the Kong as well, giving it some more grip

Yes, definitely!

Sweet! Please post some pics of that Spaceview. Mine is from ‘73, your ‘64 is an early one

Ok! Managed to get the back off without destroying anything!

Model is a GX 6558
Other stamped marking is E21663

Movement is a caliber 500

Still not sure of exact year... didn't want to take it apart any further... where is the serial number on the movement? Or is there another way to verify?

Turn the rotor 180 deg and snap another shot.

Just one thing about the apparent date from the Omega Vintage Watch Database: the dates can be generalized. I have a ref GX 6250 for which the Database gives the year as 1961, but the watch was given as a service award in 1957 ( as engraved on the back of the watch).

and now we can deduce what GX means, 14K solid gold. My KX 6275 is 14K gold-filled.
