Zenith G.F.J Calibre 135 platinium Lapis Lazuli dial leather strap 39 mm

A Tribute to 160 Years of Watchmaking Excellence

To celebrate 160 years of horological passion, Zenith unveils an exceptional creation: the G.F.J. – Calibre 135, a commemorative timepiece limited to just 160 pieces. Named after Georges Favre-Jacot, the visionary founder of the Manufacture, this watch pays homage to Zenith’s legacy of precision while embracing refined modernity.

A Legendary Movement

At the heart of this timepiece lies the iconic Calibre 135, one of the most accurate movements ever made. It famously earned five consecutive first prizes at the Neuchâtel Observatory Chronometry Competition between 1950 and 1954. Reimagined today with COSC certification, the movement now offers a 72-hour power reserve, optimized gear train geometry, and a double arrow-shaped regulator for highly precise adjustments.

Refined, Noble Design

The 39 mm platinum 950 case is a study in elegance, featuring sculpted stepped lugs and a sleek profile. The dial captivates with its depth and materials: a lapis lazuli center, mother-of-pearl small seconds, and a “brick” guilloché outer ring with applied white gold indexes — a nod to the distinctive brick façade of the Zenith Manufacture. Every detail reflects exceptional craftsmanship and architectural inspiration.

Exquisite Finishing

The movement is finished to the highest standards, with hand-applied anglage, guilloché bridges, and updated components to enhance reliability and accuracy. The watch is delivered with a dark blue alligator leather strap and a platinum pin buckle, alongside additional calfskin leather straps. A platinum bracelet, designed in vintage style, is available upon request.

Between Heritage and Innovation

A true collector’s piece, the Zenith G.F.J. is a limited edition watch that embodies Swiss horological excellence, blending timeless tradition with contemporary sophistication.
