Nivada Grenchen Watch: F77 MKII Jade 100th Anniversary Edition

Nivada Grenchen: The F77 MKII Jade, a brand centenary edition with a natural jade dial

The Nivada Grenchen F77 MKII Jade 68055A77 celebrates the Swiss house’s 100th anniversary with a major evolution of its iconic integrated-bracelet sports watch. Its 38 mm 316L stainless steel case houses a dial crafted from natural jade, with green hues that vary depending on the light. Since every stone has its own variations, each Nivada Grenchen F77 Jade is thus endowed with a naturally unique dial.

The Nivada Grenchen F77 Jade retains the angular and integrated architecture directly inspired by the F77 of the 1970s, but now moves to a 38 mm diameter, 46.2 mm lug-to-lug, and 11.50 mm thickness. Its dial features brilliant silver applied indices and white luminescent dots, while a double-domed anti-reflective sapphire crystal protects the whole assembly.

At the heart of the centenary Nivada Grenchen F77 is the La Joux-Perret G101, a Swiss automatic caliber specifically introduced in this anniversary collection. It operates at 28,800 vibrations per hour / 4 Hz, features 24 jewels, and delivers 68 hours of power reserve. This no-date movement prioritizes a clean display of hours, minutes, and the central seconds hand, and remains visible through the transparent sapphire caseback of the F77 Jade.

In the 68055A77 configuration, the Nivada Grenchen F77 Jade is mounted on the integrated stainless steel bracelet which is one of the fundamental elements of the F77. It measures 22 mm at the case and 16 mm at the clasp according to Nivada Grenchen. With its 10 ATM / 100-meter water resistance, its natural stone dial, and its visible La Joux-Perret movement, this F77 Jade directly combines the historic seventies aesthetic of Nivada Grenchen with contemporary Swiss mechanics.

Why choose this watch?

The Nivada Grenchen F77 MKII Jade 68055A77 stands out primarily for its genuine natural jade dial. Unlike a printed or lacquered finish, each F77 Jade presents its own variations in shade and texture. This uniqueness is complemented by an important mechanical evolution: the La Joux-Perret G101 provides this Nivada Grenchen F77 with a 4 Hz frequency, 24 jewels, and above all, a 68-hour power reserve.

The Nivada Grenchen F77 Jade simultaneously retains the codes that define the F77: compact case, integrated bracelet, 1970s geometric aesthetic, and all-steel construction. The double-domed anti-reflective sapphire, transparent caseback, and 100-meter water resistance make this F77 Jade as technically interesting as it is visually. For its centenary, Nivada Grenchen has thus evolved one of its most recognizable silhouettes without altering its identity.

About the Nivada Grenchen brand

Founded in 1926 in Grenchen, Switzerland, Nivada Grenchen distinguished itself during the 20th century with collections such as the Antarctic, the Chronomaster Aviator Sea Diver, and the F77. Relaunched in the modern era, the house draws on its archives to put its historical models back into production while evolving their movements, materials, and finishes.

To celebrate its centenary in 2026, Nivada Grenchen has partnered with La Joux-Perret to create a new generation of F77s with natural stone dials. The Nivada Grenchen F77 Jade thus combines natural jade with the Swiss G101 caliber and a new transparent sapphire caseback. With the F77, Nivada Grenchen directly connects its 1970s integrated design to a more contemporary approach to materials and mechanics.
