Nivada Grenchen F77 MK2 Green Aventurine Dial 68053A77

The Nivada Grenchen F77 MK2 SST Green Aventurine Ref. 68053A77 brings a natural-stone dial to the brand’s revived integrated-bracelet sports watch, whose design traces back to the original F77 introduced in 1977. The MK2 retains the collection’s distinctive 1970s architecture, including its angular case, octagonal-style bezel with exposed screws, and integrated stainless steel bracelet, while refining the proportions and ergonomics for modern wear. Its 38mm case is crafted from 316L stainless steel and measures 12.2mm thick and 46.2mm lug-to-lug, with alternating brushed and polished surfaces emphasizing the sculpted construction. The centerpiece is the genuine green aventurine dial, whose natural mineral inclusions create subtle variations in texture and sparkle, meaning no two examples will appear exactly identical. Shiny silver applied indexes with luminous accents keep the display clean, while a double-domed sapphire crystal with anti-reflective coating, screw-down crown, and 100 meters of water resistance give the F77 genuine everyday practicality.

Inside is the Swiss-made Soprod P024 automatic movement in a no-date configuration, allowing the aventurine dial to remain uninterrupted and symmetrical. The 25-jewel caliber operates at 28,800 vibrations per hour and provides approximately 38 hours of power reserve, driving central hours, minutes, and sweeping seconds. The MK2 generation also brings meaningful refinements to the F77 platform, including a redesigned case profile, more curved lugs, and an updated integrated bracelet intended to sit more naturally on the wrist. By combining the unmistakable integrated-bracelet styling of the original 1977 F77 with modern construction and a naturally unique green aventurine dial, the 68053A77 offers a particularly distinctive version of Nivada Grenchen’s revived sports-watch design—one where every individual watch has its own pattern and character.

Nivada Grenchen, established in 1926 in Grenchen, Switzerland, quickly became renowned for its rugged tool watches that pushed the boundaries of horological innovation. The brand solidified its reputation with the introduction of the Antarctic in 1950, the first waterproof automatic watch. This timepiece gained fame when it accompanied members of the U.S. Navy's Operation Deep Freeze I during their South Pole expedition from 1955 to 1956.



In 1961, Nivada Grenchen launched the Chronomaster, a versatile waterproof chronograph designed for aviators, divers, and sports enthusiasts. The company continued its innovative streak with the release of the Depthomatic in 1964, the first diver's watch featuring a depth indicator, followed by the Depthmaster in 1965, capable of withstanding pressures up to 1,000 meters.

After a period of dormancy, Nivada Grenchen experienced a rebirth in 2018, reintroducing two of its most iconic models—the Chronomaster Aviator Sea Diver and the Antarctic—at the forefront of its revival. The relaunch paved the way for the brand’s enduring appeal among modern watch enthusiasts while honoring its storied heritage.
