Zenith 30.1865.0135/56.M0135 description

The Zenith G.F.J. Calibre 135 30.1865.0135/56.M0135 debuted in 2026 as a limited edition of 161 pieces in 18-carat yellow gold, presented here on a matching seven-row yellow gold bracelet. It retains the same 39.15mm yellow gold case, stepped bezel, curved stepped lugs, and manually wound Calibre 135 as the strap-fitted version, while replacing the leather strap with a full gold bracelet and double folding clasp.

Its case measures 39.15mm in diameter, 10.5mm in thickness, and 45.75mm lug to lug. The watch is fitted with a domed sapphire crystal with anti-reflective treatment on both sides and a transparent sapphire caseback. Water resistance is rated to 5 ATM.

The dial follows a three-part construction, with an outer brick-pattern guilloché ring, a jasper bloodstone centre, and an oversized mother-of-pearl small-seconds counter at 6 o’clock. Yellow gold applied indices and dots are paired with faceted yellow gold hands. As the bloodstone is a natural material, each dial differs in veining and inclusions.

Inside is the manually wound Calibre 135, a 22-jewel movement operating at 18,000 vibrations per hour, or 2.5Hz, with a power reserve of 72 hours. It displays central hours and minutes with small seconds at 6 o’clock and incorporates a stop-seconds mechanism. The movement is COSC-certified and finished with Côtes de Genève and a ruthenium treatment
