For the second edition of its Double Signed program Zenith partnered with independent watchmaker, and guilloché expert, J.N. Shapiro. Crafted in 18K rose gold, the Zenith G.F.J. Calibre 135 Double Signed J.N. Shapiro pairs the legendary movement with a hand-made silver dial produced in Shapiro’s California atelier. Its decorated with three distinct guilloché motifs. A barleycorn pattern adorns the outer section, while the center of the dial sports a basketwork motif. The small seconds sub-dial is distinguished by Shapiro’s signature Infinity Weave. These contrasting textures are framed by applied rose gold rings, hour markers and plates bearing the double signature Zenith | J.N. Shapiro, as well as the G.F.J. initials.

Visible through the sapphire caseback, the bridges of the Calibre 135 feature a distinctive finish known as damaskeening. Combining elements of Côtes de Genève and guilloché, this decorative technique is frequently found on American pocket watches. The hand-wound Calibre 135 is equipped with a large variable-inertia balance wheel with a Breguet overcoil. As well a double arrow-shaped regulator for fine adjustments. This modern re-engineering of Zenith’s classic movement offers an extended 72-hour power reserve and incorporates a stop-second mechanism.
The 39mm G.F.J. Calibre 135 Double Signed with J.N. Shapiro comes with three distinct leather straps: brown Cordovan leather, beige nubuck alligator pattern leather and black calf leather. Its 18k rose gold pin buckle is engraved with the G.F.J. initials. Available in a limited edition of 25-pieces.
