About this product
Dark grey with diamond hour markers in solid 18 ct yellow gold under a diamond-set bezel. Charcoal against solid gold ringed by diamonds is the sharpest contrast the range allows — the coolest possible dial in the warmest possible setting. President bracelet. Calibre 2236 inside gives roughly fifty-five hours with a silicon Syloxi hairspring immune to magnetic fields.
This watch comes with the manufacturer's warranty card, backed up by our own Alan Furman & Co warranty.
