UN1 Ulysse Nardin Maxi Marine Black Sea Diver. Reference 263-92-3C. Watch measures a wicked 45.8mm and is made from black PVD steel. Automatic UN in-house movement caliber UN-26. Sapphire crystals on both sides of the case. Waterproof 20ATM or 200 meters. Functions are hours, minutes, small seconds, date and power reserve. This watch is fitted with the original black (sized) rubber bracelet with integrated steel PVD links. This watch is complete with the original box and papers but sadly the original owner misplaced the warranty card. Naturally we will warrant this watch for 6 months as we do with all out watches unless stated otherwise. Rare watch and a wicked combination in black with red! SOLD
