Ulysse Nardin Diver X Skeleton 44mm Black DLC Titanium Case

Ref. 3723-170-2B/3A

The 44mm black DLC titanium case carries a 15.7mm profile, with a unidirectional rotating bezel made from Carbonium®, an upcycled carbon composite also used in aerospace. The domed sapphire crystal sits above a fully skeletonised dial structured around a signature X form, revealing the gear train and barrel of the automatic UN-372 calibre beneath. That movement runs a silicon oscillator, balance spring, anchor, and escapement wheel, with a 96-hour power reserve. Azure blue accents run through the dial, crown protector, and light blue rubber strap, which fastens with a titanium pin buckle. Super-LumiNova coats the hand markers and hour batons, and the watch is rated to 200 metres.
