About this product
Black mother-of-pearl with diamond markers on the Jubilee bracelet, 31mm Yellow Rolesor, domed bezel. Dark nacre behaves nothing like a black lacquer dial — it holds colour in it, shifting through grey, green and faint violet as the wrist moves, and no two are alike. Against yellow gold the warmer tones surface. Calibre 2236 drives it at roughly fifty-five hours with a silicon Syloxi hairspring.
This watch comes with the manufacturer's warranty card, backed up by our own Alan Furman & Co warranty.
