About the Zenith 40.1865.0135/51.M0135
The Zenith G.F.J. 40.1865.0135/51.M0135 is a limited edition of 160 pieces created for the brand’s 160th anniversary and presented here on a matching platinum bracelet.
The watch is housed in a 39 mm round case crafted from platinum, featuring a stepped bezel and curved stepped lugs. Sapphire crystals are fitted on both sides. Water resistance is specified at 5 ATM.
The dial is constructed in three parts and combines a brick-pattern guilloché centre, a lapis lazuli section, and a mother-of-pearl element. The layout displays hours, minutes, and small seconds, with the materials and finishes differentiated across the dial surface.
Powering the watch is the manually wound calibre 135. The movement operates at a frequency of 2.5 Hz and incorporates an oversized balance with regulation screws, a Breguet overcoil, and a double arrow-shaped regulator. A stop-seconds mechanism is included, and the power reserve is specified at approximately 72 hours.
This configuration is delivered on an integrated platinum bracelet, replacing the leather strap options supplied with other executions of the G.F.J. model.
