Common questions about the Omega Seamaster 166.077

What movement is in the 166.077?

Caliber 1002.

Is the 166.077 water resistant?

It is rated to 600 meters, about 1969 feet. That is a diving rating: it is built for scuba use, not just for getting wet. One caution that applies to every watch on this page: a water resistance figure describes a new watch with fresh gaskets. On a piece that is years past its last service, treat the rating as unknown until it has been pressure tested.

When was the Omega Seamaster 166.077 made?

Omega produced this reference from 1970 to 1979. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.

Does the 166.077 have a nickname?

Seamaster Ploprof 600M. Collector nicknames are not official Omega names, but they are what people actually search for and what they are called across a showroom.
