About this product
Silver sunray under a diamond-set white gold bezel. Dial and case in the same cool register with a ring of diamonds between them — the sunray brushing on the dial and the stones on the bezel catch light in two entirely different ways, which is all the variation the watch needs. In 31mm on the Oyster bracelet. Calibre 2236 inside, roughly fifty-five hours.
This watch comes with the manufacturer's warranty card, backed up by our own Alan Furman & Co warranty.
