About the G.F.J. family
The G.F.J. was introduced in 2023 as a tribute to Zenith's founder, Georges Favre-Jacot. It brought back the caliber 135, a hand-wound movement that won many observatory chronometry competitions in the mid-20th century, in a limited edition.
The catalog lists references in platinum, yellow gold and tantalum. The caliber 135 was originally developed in the late 1940s, and its return was one of the brand's more technical anniversary projects. Dealers check the edition number, dial and papers.
