Ulysse Nardin Marine Torpilleur 42mm Steel — Blue Dial | Ref. 1183-310-7MIL/43

Torpilleur — torpedo boat — names this Marine reference after the swift, lethal surface craft that rewrote naval doctrine at the turn of the twentieth century, and the nomenclature carries through into the watch's design attitude. The 42 mm stainless steel case strikes a balance between the Marine Chronometer's classical navigation instrument proportions and the assertive bulk of a purpose-built diving reference, a middle path that renders the Torpilleur equally appropriate for deck wear and boardroom duty. The blue dial honours the maritime tradition most directly: no colour communicates the ocean more immediately, and against stainless steel the effect is both vivid and composed.

The Calibre UN-118 self-winding movement inside this reference traces its lineage directly to Ulysse Nardin's marine chronometer development programme. Delivering approximately 60 hours of power reserve, the UN-118 provides three days' operation between winding — adequate for a weekend journey without requiring the watch to accompany the wearer at all times. Date indication at a classically positioned aperture serves the practical requirements of a daily-use reference, while the movement's self-winding architecture via bidirectional rotor ensures that active wearers will rarely allow the mainspring to deplete meaningfully. Water resistance to 50 metres covers the full range of recreational aquatic activity.

The steel bracelet with folding buckle elevates the Torpilleur's versatility beyond what a strap-only offering could achieve — on a bracelet the 42 mm case reads as a serious sports-dress piece capable of accompanying business meetings, sailing weekends, and everything between. The reference designation contains the "MIL" identifier, signalling that this reference was developed in part with military operational requirements informing its functional specification. At $7,190 the Marine Torpilleur 42 mm is the most accessible entry into the Marine collection without sacrifice of authentic calibre content — a watch that carries the full weight of Ulysse Nardin's naval heritage within a proportion and price point suited to daily active wear.
