Nivada Grenchen enjoys a place in the mid 20th century as one of the premier quality watchmakers building timepieces for exploration. Its famous Chronomaster, Depthmaster, and Antarctic models are all legends in their respective fields. The F77, introduced in 1977, marked Nivada Grenchen’s foray into the “sport chic” watch category. Now reintroduced for the 20th century, the F77 remains true to its heritage while packing plenty of modern features.

The F77’s stainless steel case remains 37mm wide and retains its historical size. This, coupled with its compact 45mm lug to lug measurement, makes it one of the most wearable sport integrated bracelet watches around. Color variations include a blue, black, and smoked dials – both with date and no date. The basket weave pattern on the dial adds depth and detail, qualities that are also obvious on the F77’s case satin and polished edges.

Inside the Nivada Grenchen F77 is the Soprod P024 movement, an automatically-winding caliber that offers both date and no-date options. (On no-date versions, you get no ghost positions.) It beats at 4Hz (28,800 vph) and offers 38 hours of power reserve. Water resistance is 100 meters.
