The F77 Chrono Mecaquartz watch brings together watchmaking sophistication and modern technology. Its tonneau-shaped case is made of 316L stainless steel, known for its durability and corrosion resistance. A matte brushed/satin finish creates an attractive contrast with the detailed dial. Measuring 38 mm in diameter and 12,20 mm in thickness, it sits comfortably on the wrist while retaining a bold, elegant look. A domed sapphire crystal adds visual appeal and excellent resistance to scratches.
The dial of the F77 Chrono Mecaquartz features a woven effect that adds texture and catches the light subtly. Predominantly gray, it has a modern, elegant look. Luminous hands and hour markers make it easy to read in low light. Alongside the classic hour, minute and second hands, the dial has two additional subdials for the chronograph: one for 24 hours and one for 60 minutes. A railroad minute track frames the dial and completes its precise look.
At the heart of this watch is a Japanese Hattori VK64 Mecaquartz movement, combining quartz accuracy with classic mechanical appeal. Its exceptional battery life of 3 years on a single battery provides lasting reliability while reducing the need for frequent battery changes and time resets.
Versatility and style define the bracelet of the F77 Chrono, available in two options to suit different occasions and preferences. Choose stainless steel with a polished finish and a fold-over clasp for a contemporary look, or black braided nylon with a hook-and-loop closure for a modern sporty touch.
The F77 Chrono Mecaquartz is at home on land and at sea, with certified water resistance up to 10 ATM. While it is not intended for deep diving, it can handle an accidental dunk, a sudden downpour or even a swim.
