Ulysse Nardin Blast Tourbillon 45mm 18ct Rose Gold Upper Case

Ref. 1725-400-3A/3A

The 45mm case pairs an 18ct rose gold upper section with a blue PVD titanium central case and bezel, finished across polished, satin-brushed, and sandblasted surfaces. At 13mm thick, it wears with some presence on the wrist. Sapphire crystal covers both the front and caseback. The skeletonised dial is built around a blue rectangle and double-X geometry, with applied rose gold baton indices and Super-LumiNova on the hands and markers. The flying tourbillon sits at six o'clock, driven by the UN-172 calibre — a platinum micro-rotor movement with a silicon escapement and roughly 72 hours of power reserve. A textured blue rubber strap with a rose gold and blue PVD folding clasp completes the watch.
