Strap for Marine Torpilleur Stainless Steel / White / Fabric

The lug width of the Ulysse Nardin Marine 1183-310-0A/0A is precisely 21mm, measured centre-to-centre between the spring bar attachment points. This specification is unique to this particular model and requires exclusively manufactured 21mm straps. Straps sized 20mm or 22mm will result either in excessive play or incompatibility.

The optimal strap material depends on intended usage context. For formal wear, we recommend vegetable-tanned alligator in deep brown tones or structured black calf leather, both of which develop natural patina over time. For maritime or sporting applications, NATO straps in cotton or vulcanised rubber provide superior water resistance and low-maintenance properties. The Marine accommodates both formal refinement and technical practicality equally well.

Strap replacement requires a spring bar removal tool, which gently depresses the lug attachment pins to create sufficient clearance for removal. Position the tool beneath the pin and apply upward pressure until space is created for the old strap to slide free. Insert the new strap by seating one end first, then press the opposite pin into its corresponding hole until an audible 'click' confirms secure placement. This procedure is recommended to be performed by an authorised service centre to prevent case damage.

Yes, aftermarket straps of superior build quality are fully compatible provided they are manufactured specifically for 21mm lug width. Mechanical compatibility is not problematic; the critical factor is the construction quality of the chosen strap. Artisanal straps engineered for this precise specification offer perfect fit alignment and temporal durability exceeding mass-market alternatives.

Leather strap longevity depends upon usage frequency, tanning method, and environmental exposure. A vegetable-tanned alligator strap, worn regularly but not daily, typically requires replacement after 3-4 years. Structured calf leather exhibits marginally extended longevity owing to denser fibre structure. Frequent exposure to perspiration, salt water, or extreme temperature fluctuations significantly reduces service life. Preventative maintenance using leather-specific conditioning oils extends replacement intervals considerably.
