Strap for Endeavour Centre Seconds, White Gold, Fumé Dial

The lug width (ansa measurement) of the H. Moser & Cie Endeavour 1343-0205 is 20 millimetres. This dimension represents the distance between the case's attachment pins and determines compatibility with watch straps. It is measured by placing a ruler along the interior side of the case, from one pin to the other, excluding the lateral shoulders of the lugs.

The ideal strap depends on usage intent and aesthetic preference. For formal contexts, a vegetable-tanned alligator in dark cognac or deep brown is recommended, as it complements the smoky dial without competing visually. For daily wear, vegetable-tanned calf leather offers softness and refinement. For weekend versatility, a sober NATO in navy blue or anthracite grey maintains aesthetic dignity. For those seeking absolute robustness, black FKM rubber creates decisive contrast with the white gold case.

Strap replacement requires careful handling given the white gold case. Use a spring bar tool (dedicated lever for the pins), inserting it gently into the lateral hole of the spring mechanism and applying controlled pressure to compress the pin. Remove the old strap, align the new one's lug with the pins, and verify that the pin fully inserts into the new strap's lugs. We recommend professional assistance if you lack experience, to prevent micro-abrasions on the white gold.

Yes, any strap with a 20mm lug width is compatible with the 1343-0205. Milano Straps designs all straps in the 20mm specification and guarantees full compatibility. Always verify the strap's lug width before purchase: an incorrectly sized strap will not insert properly into the case's lugs, compromising both aesthetics and functionality.

Leather strap durability varies based on usage patterns, climate, and tanning quality. A vegetable-tanned calf strap, used daily under normal conditions, typically lasts 3–5 years before replacement is necessary. In humid climates or with intensive use, longevity decreases to 2–3 years. Alligator and shell cordovan straps, being more resistant, can last 5–7 years. Proper maintenance—drying after water exposure, periodic water-repellent treatments—significantly extends lifespan.
