Strap for Endeavour Centre Seconds, White Gold, Black Baguette Dial

The lug width of the H. Moser & Cie Endeavour 1343-0203 is 20 millimetres. This dimension is measured between the two horizontal lugs that protrude from the case. Verifying this measurement before ordering a compatible strap is essential to ensure precise fit without lateral play.

For the Endeavour 1343-0203, straps in superior-grade alligator with vegetable tanning, or traditionally worked Tuscan calf, are recommended. Both maintain the aesthetic minimalism of the white gold case and develop natural patina over years. Alternatively, vulcanised rubber straps or grey NATO fabric offer versatility without compromising elegance.

To change the strap, remove the spring bars that unite the strap to the case. Using a spring bar remover tool, gently depress the small spring inside each bar and extract the old strap. The new strap is inserted by seating the spring bars into the corresponding lug holes. Exercise caution to avoid scratching the white gold case, or entrust the operation to a professional watchmaker.

Yes, absolutely. The artisanal strap market offers high-quality alternatives perfectly compatible with the 20mm lug width. Choose materials and finishes coherent with the minimalist style of the 1343-0203: natural alligator, aged-patina calf, or premium technical materials such as rubber and textiles will guarantee both aesthetic coherence and durability.

The lifespan of a leather strap depends on usage and material quality. An alligator or vegetable-tanned calf strap, if exposed to normal wearing conditions (not prolonged contact with water or intense humidity), can remain functionally and aesthetically pleasing for 4–7 years before replacement is necessary. The patina developing during this period is part of the natural strap's appeal. Periodic protection with vegetable oils or waxes significantly extends longevity.
