Strap for Endeavour Moon Rose Gold / Blue Fumé

The H. Moser & Cie Endeavour 1348-0100 is equipped with a 20-millimetre lug width. This measurement is precise and permits only straps designed for 20mm attachment points. Correct measurement is taken from the inner base of one lug to the other, ensuring the strap inserts without improper pressure on the rose gold case lugs.

For this rose gold 5N timepiece, an alligator strap with vegetable tanning in dark brown or cognac tonality represents the optimal choice. The natural grain texture of alligator leather dialogues harmoniously with the case without visual competition, and the patina developing over time parallels that of the gold. Shell cordovan, more coriaceous with an almost lustrous surface, is equally excellent for those desiring quality assertion. For daily wear, fine-grained calf leather offers balanced suppleness and longevity.

Replacement requires removal of the spring bars linking the original strap to the case attachment points. Using a dedicated tool, apply light pressure to compress the spring bar mechanism, permitting removal from the lug. Once freed, the new strap (ensuring it is 20mm width) is inserted by orienting the bars into the attachment points and allowing the spring to reposition naturally. The operation demands delicacy to avoid scratching the rose gold case.

Yes, any quality strap constructed for 20mm lug width is mechanically compatible with the 1348-0100. We recommend selecting artisanal straps respecting the timepiece's quality standards: leather must source from certified tanneries, stitching must be precise, and the buckle or deployante must be in noble metal (steel, rose gold, or titanium) to prevent aesthetic degradation adjacent to the gold.

A naturally tanned leather strap, if properly maintained, lasts approximately 3-5 years of daily wear. Lifespan depends on environmental exposure (humidity, heat, solar exposure), frequency of wear, and maintenance practices. Leather exposed to constant humidity degrades more rapidly; conversely, dry environments extend longevity. Occasional conditioning with leather-specific products protects fibre integrity. Should the strap manifest cracking, excessive stretching, or loss of buckle elasticity, replacement is advisable.
