Time to move this one on as it's not getting much wrist time. A very nice watch, I just prefer bracelets over straps.

Gruppo Gamma Divemaster
Blue bezel, blue dial (subtle gradient effect)
44mm case, ETA 2824 movement

Includes case, card, Gruppo Gamma rubber dive strap and GG fabric strap.

Reasonable offers will be considered.

Overall condition is excellent.
One thing to note -- when winding by hand, the crown wants to screw in rather than wind freely. It doesn't impact the rotor, power reserve, time setting nor time keeping -- ONLY winding by hand. Once you are aware of it, it's no problem to wind and causes no problems. To me, it's a non-issue, but I want to be fully transparent.
