This Omega F300 chronometer quartz electronic watch is an unpolished and original 1970s example. $350 was just spent on a professional overhaul of the movement, which is accurate and working perfectly. The 41mm stainless steel case is very avant-garde, never polished and has its original crystal and winding crown. The original dial and hands look great. This is a large and sprawling watch on the wrist that will attract many eyes.
