I turn to the brain trust for watches...A guy I know took the Omega Seamaster Automatic into a pawn shop and put the watch in an XRF machine. The results came back that the watch was 13.6k gold....Nothing is marked on the back to indicate it is gold.

Is this considered a 14k watch? Any chance it is GF?

The key to this is the model number which will help indicate the materials. Seamaster is a very varied model line and has changed dramatically over time.

Omega does seamasters in gold. I'm not sure what you mean "GF"

My non professional experience is that if an Omega Seamaster looks like gold, it's either 14K or 18K gold filled.

I have an Omega Seamaster from the late 80's and it is 18K and steel. No where is the 18K marked on the case.

GF=Gold Filled, when talking about gold.

Omega only makes solid gold watches. They stopped using gold capping and gold filled in the 80's.

Usually they are 18kt solid, so it could be an older to 1980s gold capped 14k.

If it has a stainless steel back, its gold capped.

Fwiw...my little Omega automatic from the early 1950's is GF.
