Nivada Grenchen Watch: F77 MKII Labradorite 100th Anniversary Edition

Nivada Grenchen: the F77 MKII Labradorite, a centenary edition of the brand with a natural blue agate dial

The Nivada Grenchen F77 MKII Labradorite 68054A77 celebrates the 100th anniversary of the Swiss watchmaker with a major evolution of its iconic integrated-bracelet sports watch. Its 38mm 316L stainless steel case houses a dial crafted from natural Labradorite, whose flashes of blue, green, and yellow vary depending on the light. As each stone displays its own unique variations, every Nivada Grenchen F77 Labradorite thus possesses a naturally unique dial.

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

At the heart of the Nivada Grenchen F77 100th anniversary edition lies 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 focuses on a clean display of hours, minutes, and the central seconds hand, and remains visible through the transparent sapphire case back of the F77 Labradorite.

In the 68054A77 configuration, the Nivada Grenchen F77 Labradorite is mounted on the integrated stainless steel bracelet that constitutes one of the fundamental elements of the F77. It measures 22mm at the case and 16mm 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 Labradorite directly combines the historic seventies aesthetic of Nivada Grenchen with contemporary Swiss mechanics.

Why choose this watch?

The Nivada Grenchen F77 MKII Labradorite 68054A77 stands out above all for its genuine natural Labradorite dial. Unlike a printed or lacquered finish, every F77 Labradorite presents its own variations in hue and texture. This singularity 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 68 hours of power reserve.

The Nivada Grenchen F77 Labradorite 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 case back, and 100 meters of water resistance make this F77 Labradorite as technically interesting as it is visually. For its centenary, Nivada Grenchen thus evolves 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 modern era, the company relies on its archives to bring its historic models back into production while updating 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 F77 watches with natural stone dials. The Nivada Grenchen F77 Labradorite thus combines natural Labradorite 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.
