Zenith · G.F.J. Calibre 135 Double Signed with J.N. Shapiro
The model in detail
Meet the watch
At first it is a classic gold watch, but the dial rewards looking section by section. Zenith has paired the G.F.J. with California workshop J.N. Shapiro, giving the silver base three distinct guilloché patterns.
The outer ring has barleycorn, the centre basketweave, and the small-seconds dial Shapiro’s Infinity Weave. These are not printed lines: the release says they are cut by hand on guilloché machines in Shapiro’s workshop.

For the modern version, the maker states around 72 hours of reserve, 2.5 Hz and American-style damaskeening on the bridges. The movement is COSC certified and Zenith says it is regulated to ±2 seconds per day; actual wrist performance can differ.
Details and limitations
The 39.15 mm rose-gold case is supplied with three leather straps. A 5 bar rating adds everyday reassurance, although finishing and the owner’s appetite for manual winding remain central to the choice.
Just 25 examples will be made. The Japanese release lists JPY 10,470,900 including tax; local price and availability should be checked with Zenith. For a collector, both the movement and the American workshop’s specific contribution matter.
