I notice on all of the all gold Rolex cases, there are these indentations you can see circled in the picture I posted below. I know one of them is a stamp with ".750" for 18k gold. Any ideas what the others are or what they are for? BTW, the picture of the watch I have is from a white gold Sub-C.

They are hallmarks.

Interesting...hallmarks, uh

I'm not sure but if that's a white gold Sub, turn that beauty around and let us see her face! :)

FWIW, her behind looks mighty pretty...

As far as I know, these hallmarks stand for:

1. The alloy (e.g. 750/-)
2. The country hallmark
3. The Kanton hallmark for the Kanton of Geneva
4. An annual hallmark to identify the year or the hallmark from the maker (in that case Rolex).

They are just hallmarks 750 indicates 75% pure gold the rest other alloy so its 18Ct.All solid gold must be hallmarked 9Ct 375, 14Ct 525,18Ct 750, and so on.Now the TT watches are mixed metals gold/ss so cannot be called gold so they are called by a made up Rolex speak word like Rolesor for steel and gold. and Rolesium,for steel and Platinum.

Very interesting.

Any idea why only on gold models?

Obviously I understand the .750 for the alloy.

Because non-precious metals are not hallmarked.

Yes, 750 is for the gold alloy (75 weight% are finegold)

On precious metals, it is required by swiss law to hallmark the pieces in a certain matter.
