This one. Jumbo (38 mm), caliber 266, 20 micron gold filled case, rose gold. Circa 1950. Crown is not original, but the rest is completely original. I am the second owner. Acquired it about 15 years ago.
I picked this up a few years ago with no info, but thought it looked ok for less than 200 GBP. I wear it infrequently, but like the understated simplicity.
It's a manual wind, but beyond that (having never opened it up) I'm not expert enough to know quite what it is. Any thoughts?
