Nivada Grenchen Watch: F77 MKII Black Shungite 100th Anniversary Edition

Nivada Grenchen: the F77 MKII Black Shungite, a brand centennial edition with a natural black Shungite dial

The Nivada Grenchen F77 MKII Black Shungite 68058A77 celebrates the Swiss brand’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 black Shungite, whose black and purple nuances shift according to the light. Because each stone possesses its own variations, every Nivada Grenchen F77 Shungite thus features a naturally unique dial.

The Nivada Grenchen F77 Shungite retains the angular, 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 assembly.

At the heart of the 100th-anniversary Nivada Grenchen F77 lies the La Joux-Perret G101, a Swiss automatic caliber specifically introduced for this anniversary collection. It operates at 28,800 vibrations per hour / 4 Hz, features 24 jewels, and delivers a 68-hour power reserve. This no-date movement favors a clean display of the hours, minutes, and central seconds and remains visible through the transparent sapphire case back of the F77 Black Shungite.

In the 68058A77 configuration, the Nivada Grenchen F77 Shungite is mounted on the integrated stainless steel bracelet that serves as one of the F77’s fundamental elements. 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, natural stone dial, and visible La Joux-Perret movement, this F77 Black Shungite directly blends the historic 1970s aesthetic of Nivada Grenchen with contemporary Swiss mechanics.

Why choose this watch?

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

About the brand Nivada Grenchen

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 contemporary era, the brand draws on its archives to bring its historic models back into production while updating their movements, materials, and finishes.

To celebrate its centennial 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 Black Shungite thus combines natural black Shungite with the Swiss G101 caliber and a new transparent sapphire case back. With the F77, Nivada Grenchen directly links its 1970s integrated design to a more contemporary approach to materials and mechanics.
