Ulysse Nardin Blast Tourbillon Free Wheel

Ulysse Nardin's Blast Tourbillon Free Wheel, reference 1760-176LE/OSM, comes in an 18 ct white gold case measuring 44 mm across. The case stands 13.46 mm thick and pairs with an alligator leather strap. A sapphire crystal covers the dial, which is finished in osmium. The manual-winding calibre UN-176 drives the watch, fitted with a flying tourbillon and a power reserve indicator showing up to 170 hours of autonomy. Ulysse Nardin produced this piece as a limited edition of just 18 examples. Water resistance is modest at 30 metres, in keeping with a watch built for the dress case rather than the diver's wrist.
