About this product
Silver sunray under a diamond-set white gold bezel. Dial and case sit in the same cool register with a ring of diamonds between them, and the sunray brushing catches light in a completely different pattern from the stones. In 31mm on the flat Oyster bracelet. Calibre 2236 inside, roughly fifty-five hours of reserve, Syloxi hairspring in silicon.
This watch comes with the manufacturer's warranty card, backed up by our own Alan Furman & Co warranty.
