About this product
White mother-of-pearl with diamond hour markers — natural nacre, so the banding across the dial and the way its iridescence moves are unique to this watch. Against yellow gold the shell warms toward cream rather than staying stark white. In 31mm Yellow Rolesor with a domed bezel, on the flat Oyster bracelet. Calibre 2236 inside, roughly fifty-five hours of reserve, Syloxi hairspring in silicon, waterproof to 100 metres.
This watch comes with the manufacturer's warranty card, backed up by our own Alan Furman & Co warranty.
