Ulysse Nardin Marine Torpilleur Steel — Black Dial | Ref. 1183-310-42/BQ

Named for the torpedo boats that represented the pinnacle of naval speed and engineering in the late 19th century, the Ulysse Nardin Marine Torpilleur occupies a specific position within the Marine family — more athletically proportioned than the formal Marine Chronometer, more technically grounded than the casual Marine Diver, and entirely representative of the brand's founding conviction that precision instruments should combine functional excellence with formal authority. The 42mm stainless steel case, finished with the polished and satin-brushed surfaces that define professional Swiss case preparation, frames a black dial calibrated for maximum legibility in any ambient light condition.

Caliber UN-118 is among the most decorated movement specifications in Ulysse Nardin's current portfolio: COSC certified to ±6 seconds per day through independent laboratory testing, and subsequently validated against the brand's own even more demanding Ulysse Nardin performance certificate. The 60-hour power reserve indicator — a practical instrument function visible on the dial — provides the wearer with an immediate read of remaining movement autonomy. The silicium and Diamonsil technology embedded in the escapement assembly ensures lubricant-free operation and anti-magnetic performance that conventional lever escapements cannot approach. The oversized seconds hand, a characteristic UN-118 display element, sweeps the dial with the authority of a precision measuring instrument.

The screw-down security crown is an engineering detail that reflects the Marine Torpilleur's genuine maritime credentials: a crown system that provides a sealed, secure interface between the winding stem and the case body, protecting the movement against water ingress under conditions of active exposure. The leather strap with folding buckle delivers the formal wrist presence appropriate to a Marine piece in this configuration. Water resistance to 50 metres covers the full range of marine surface activities. For the collector seeking a movement of the highest certified standard within a Marine case at a relatively accessible price point, the Torpilleur with UN-118 represents exceptional value within the Ulysse Nardin collection.
