Ulysse Nardin Hourstriker Phantom

Ulysse Nardin's Hourstriker Phantom, reference 6103-132, has a 43 mm titanium and steel case. The dial sits under a sapphire crystal, and the case houses the self-winding calibre UN-610, with 40 hours of power reserve. This is a limited edition, one of 85 pieces made in partnership with Devialet. The standout complication is the hours and minutes repeater, which chimes the hours on demand rather than simply displaying them. An alligator leather strap closes the piece on the wrist. Water resistance is modest for the type, and the case is rated to 30 metres.
