FAQ
Is the F77 automatic or quartz?
The F77 is automatic. The Soprod P024 winds itself from the motion of your wrist, so it needs no battery. A full wind holds roughly 38 hours, so it keeps running overnight off the wrist; left longer it stops and restarts once you wear or hand-wind it.
What movement does the F77 use?
The F77 is powered by the Soprod P024 from Soprod, an automatic caliber with 25 jewels, a 38-hour power reserve, and a 28,800 bph beat rate. Being automatic, it winds from the motion of your wrist and needs no battery.
Does the F77 have a date?
Yes — the F77 has a date display on the dial. The date advances automatically as the movement runs, so the current day of the month is always visible at a glance, and you can set it from the crown after the watch has been left to stop.
How water resistant is the F77?
The F77 is rated to 100 m. That covers swimming and snorkelling, though hot water and direct high-pressure water are best avoided, and it is not intended for scuba diving. Whatever the rating, avoid operating the crown or pushers underwater, and have the gaskets checked periodically to keep it reliable.
What movement does this F77 use?
Nivada lists the F77 SST Black MK1 with the Soprod P024 automatic movement.
How large is the F77?
The official Black MK1 page lists a 37mm case.
Is the bracelet integrated?
Yes. This F77 configuration uses an integrated 316L stainless-steel bracelet.
