The F77 SST Black MK2 41mm takes the 1977 integrated sports watch to a larger case. The black woven carbon-look dial adds texture and depth, reflecting light with a subtle mechanical sheen, while shiny silver applied indexes keep the time easy to read.
After the 37 mm F77 brought the line back, the 41 mm case gives it more wrist presence while preserving the sharp geometry of the 1977 design. The MK2 profile is thinner, the lugs more curved, and the integrated steel bracelet, 24x18 mm with a push-button deployant buckle, has been redesigned for comfort. The 316L stainless steel alternates satin-brushed and polished surfaces; the case measures 12.05 mm thick and 50 mm lug to lug.
Inside, the Swiss Soprod P024 automatic movement, available with or without date, beats at 28,800 vibrations per hour with a 38-hour power reserve, visible through a sapphire caseback. Each piece is assembled and tested in Switzerland. A double-domed sapphire crystal, a screw-down crown and 10 ATM water resistance make it a daily companion, and a leather strap is also offered. The original size is the F77 SST Black MK2 38mm; see all F77 Black models.
