Launched in 2026, the Zenith G.F.J. Calibre 135 30.1865.0135/56.M0135 is part of a limited series of 161 watches, crafted from 18-carat yellow gold and showcased on a stunning seven-row yellow gold bracelet. This model shares the same specifications as its leather strap counterpart with a 39.15mm yellow gold case featuring a stepped bezel and curved lugs, but it replaces the leather strap with an elegant gold bracelet that fastens with a double folding clasp.

The watch case maintains a diameter of 39.15mm and thickness of 10.5mm, while measuring 45.75mm from lug to lug. It is adorned with a domed sapphire crystal treated for anti-reflective qualities on both sides, complemented by a transparent sapphire caseback, providing water resistance up to 5 ATM. The dial features a unique three-part design: an outer ring with a brick-pattern guilloché, a central jasper bloodstone, and a prominent mother-of-pearl small-seconds counter positioned at 6 o'clock. Faceted yellow gold hands and indices enhance the luxurious feel, while the natural characteristics of the bloodstone mean that each dial showcases its own unique veining.

At the heart of the watch lies the manually wound Calibre 135, a 22-jewel movement that operates at a frequency of 18,000 vibrations per hour (2.5Hz) and boasts a 72-hour power reserve. The movement offers central hours and minutes, as well as a small seconds display at 6 o'clock, and includes a stop-seconds feature. It is certified by COSC and is beautifully finished with Côtes de Genève and a ruthenium treatment.
