Strap for Marine Torpilleur Stainless Steel / White / Rubber

The lug width of the Ulysse Nardin Marine 1183-310-3/40 is 21.00mm. This measurement, also known as strap width, is measured internally between the strap lugs on the case. The lug depth is approximately 12mm, an important parameter when selecting compatible straps.

For the Marine 1183-310-3/40, we recommend straps in alligator with vegetable tanning (dark brown or black tones), European calf for natural patina development, NATO in grey Cordura for technical aesthetics, or vulcanised FKM rubber in graphite grey. Your choice depends on daily wear and the desired chromatic dialogue with the blue dial.

To change the strap, use a spring bar tool. Position the watch on a stable surface and insert the thin end of the tool into the lower notch of the spring bar until the internal spring compresses. Extract the bar with a decisive movement. Repeat on both sides. Insert the new bars into a compatible 21mm strap, then secure them to the case using the reverse procedure.

Yes. The Marine 1183-310-3/40 accepts quality aftermarket straps with a 21mm lug width. Always verify the internal dimensional tolerance (21.00mm) and lug depth (approximately 12mm). Artisanal straps in vegetable-tanned leather, alligator, NATO, or rubber are fully compatible and allow you to personalise your watch aesthetics.

The lifespan of a leather strap depends on the tanning method and usage. A strap in European calf with vegetable tanning lasts 3-4 years with regular maintenance (avoid prolonged water exposure, apply protective balm 2-3 times annually). Alligator, being more durable, can last 5-6 years. Vulcanised rubber has a longer lifespan (7-10 years) but requires frequent cleaning.
