About this product
Silver in solid 18 ct white gold under a diamond-set bezel, on the President bracelet. Silver dial, white gold case, diamond bezel — a watch in which every element sits in the same cool register and the only variation is how each surface handles light. Calibre 2236 inside, roughly fifty-five hours of reserve, silicon Syloxi hairspring, sealed by a screw-down Twinlock crown.
This watch comes with the manufacturer's warranty card, backed up by our own Alan Furman & Co warranty.
