The F77 SST Green Aventurine MK2 is a 38 mm Swiss automatic watch with a natural green aventurine dial, set in the integrated steel case and bracelet of the F77, a design that goes back to 1977. Each dial shows its own mineral landscape: deep emerald tones, crystalline fragments and organic inclusions formed in the stone. No two are identical.
The redesigned MK2 case is 12.2 mm thick, with more curved lugs for a closer fit, drilled lugs for quick strap changes and a redesigned integrated bracelet. The octagonal steel bezel is held by eight screws.
Brushed and polished surfaces alternate across the case to sharpen the contrast with the green stone. Shiny silver applied indexes with white Super-LumiNova dots keep the dial readable after dark.
Inside, the Swiss Soprod P024 automatic beats at 4 Hz on 25 jewels and delivers a 38-hour power reserve. A screw-down crown and a double-domed sapphire crystal with anti-reflective coating bring water resistance to 10 ATM, or 100 m. Choose the integrated steel bracelet, a canvas velcro strap or black rubber. More natural dials are in the stone dial watches range.
