Ulysse Nardin Blast Tourbillon

Ulysse Nardin's Blast Tourbillon, reference 1723-400-3A/03, has a 45 mm case in titanium and ceramic. The case measures 12.6 mm thick, a substantial but wearable profile for a watch of this diameter. A sapphire crystal covers the dial, which shows only hours and minutes to keep the layout uncluttered. The self-winding calibre UN-172 drives the watch, with a flying tourbillon visible on the dial and a power reserve of 72 hours. This is a flying tourbillon built for daily wear rather than display alone. A rubber strap completes the piece, matching the case's technical character. The case holds a 50 metre water resistance rating.
