F77 SST Blue Mk2 – 38mm

The Nivada Grenchen F77 Blue MK2 (38 mm) is a modern reinterpretation of the brand’s 1977 integrated‑bracelet sports watch, refined with updated ergonomics and a striking natural‑stone dial. Its 38 mm case, crafted from 316L stainless steel, features brushed surfaces with polished bevels and measures 12.2 mm thick with a 46.2 mm lug‑to‑lug, giving it compact yet substantial wrist presence. The MK2 redesign introduces more curved lugs for improved comfort, drilled lug holes for easier strap changes, and a slimmer profile compared to the original. An octagonal bezel with eight exposed screws reinforces the watch’s angular, late‑1970s aesthetic, while a double‑domed sapphire crystal with anti‑reflective coating ensures clarity and durability. The watch is equipped with a signed screw‑down crown and offers 10 ATM (100 m) water resistance, making it suitable for everyday wear.

At the heart of the F77 MK2 is the Swiss‑made Soprod P024 automatic movement, a reliable calibre operating at 28,800 vph (4 Hz) with 25 jewels and a 38‑hour power reserve. It provides hours, minutes, and central sweeping seconds, with hacking capability for precise time setting. The movement is housed beneath a 316L stainless‑steel caseback, maintaining the watch’s robust construction.

The defining feature of this model is its Dark Blue Aventurine dial, cut from genuine stone and enriched with natural metallic inclusions that shimmer subtly under changing light. Each dial is unique due to the organic mineral structure. Applied shiny silver indices and Super‑Luminous white dots enhance legibility, while the baton‑style hands maintain the clean, architectural look of the original F77 design. The watch is fitted with an integrated stainless‑steel bracelet (22 mm tapering to 16 mm), redesigned for smoother ergonomics and a more comfortable wrist profile.
