Nivada Grenchen Watch: F77 MKII Blue Agate 100th Anniversary Limited Edition

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

The Nivada Grenchen F77 MKII Blue Agate 68061A77 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 blue Agate, the blue hues of which vary depending on the light. As each stone displays its own unique variations, every Nivada Grenchen F77 Agate thus features a naturally unique dial.

The Nivada Grenchen F77 Agate retains the angular, integrated architecture directly inspired by the 1970s F77, 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.

At the heart of the 100th-anniversary 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, contains 24 jewels, and delivers a 68-hour power reserve. This no-date movement prioritizes a clean display of hours, minutes, and central seconds, and remains visible through the F77 Agate's transparent sapphire case back.

In the 68061A77 configuration, the Nivada Grenchen F77 Agate is mounted on the integrated stainless steel bracelet that serves as one of the fundamental elements of the F77. According to Nivada Grenchen, it measures 22 mm at the case and 16 mm at the clasp. With its 10 ATM / 100-meter water resistance, natural stone dial, and visible La Joux-Perret movement, this F77 Agate directly combines the historical seventies aesthetic of Nivada Grenchen with contemporary Swiss mechanics.

Why choose this watch?

The Nivada Grenchen F77 MKII Blue Agate 68061A77 stands out primarily for its genuine natural Agate dial. Unlike a printed or lacquered finish, every F77 Agate features its own variations in shade and texture. This uniqueness is complemented by a significant 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.

At the same time, the Nivada Grenchen F77 Agate 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-meter water resistance make this F77 Agate as technically interesting as it is visually appealing. 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 made a name for itself throughout the 20th century with collections such as the Antarctic, the Chronomaster Aviator Sea Diver, and the F77. Relaunched in the modern era, the company draws on its archives to put its historical 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 Agate thus pairs natural blue Agate 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.
