It doesn't get any points for brand recognition...
..but it's a great classic vintage diver - from the decent end of the spectrum. No chromed case here - but a heavy polished stainless steel, with a screw down crown, and look at that fab rotating bezel! It has a 25 Jewel 21600 ETA 2783 quickset - so from Roland's dates the watch is 1969-76 (I would have said the style was more 1960s end, its not chunky enough to be later). This was a cased locally (in a Swiss case) to get around import laws and distribution rules and sold through a local goldsmiths chain. The watch came from a retiring watchmaker who used to assemble them in the evenings under contract. Probably the whole watch is NOS, I don't see any signs of wear and considering where it came from. That said, its been knocking around in a draw for 40 odd years, so it has the odd mark.
Lots of photos:
Original unmarked 22mm Tropic Sport strap
Pretty dial, red tick marks.
I am really digging this groovy bezel
Seriously thick crystal
Teaser, no wabi.
The money shot - BTW, I am not familiar with the logo on the rotor.
Keeper. Nuf said.
