The Endeavour 1343-0100, seen from the bench

The H. Moser & Cie Endeavour 1343-0100 is a 40.8mm rose gold case watch with a minimalist aesthetic and argenté dial featuring leaf-shaped hands. It is powered by the in-house HMC 343 caliber, which displays hours, minutes, seconds, and a power reserve indicator. The 20mm lug width is proportionally designed for visual harmony and ensures compatibility with compatible straps.

Frequently asked questions

What is the lug width of the H. Moser & Cie Endeavour 1343-0100?

The lug width of the H. Moser & Cie Endeavour 1343-0100 is 20mm. This measurement is proportioned to the 40.8mm case diameter and maintains the visual harmony characteristic of this model. To verify compatibility with a new strap, measure the distance between the two spring bars (the protrusions that attach the strap to the case).

What is the best strap for the H. Moser & Cie Endeavour 1343-0100?

The choice depends on intended use and aesthetic preference. For absolute elegance, we recommend an alligator strap with vegetable tanning, which develops a golden patina over time. For daily versatility, a chocolate brown calf strap echoes the smoked dial. A cotton-polyester NATO in charcoal grey offers contemporary styling, whilst FKM rubber in black provides grip and durability for sporting environments.

How do you change the strap on the H. Moser & Cie Endeavour 1343-0100?

Remove the strap by extracting the spring bars from the case lugs. Position the watch on a soft surface, locate the small holes near the lugs, and use a spring bar removal tool (often supplied with the new strap) to extract the metal pins. Align the new strap correctly and reinsert the spring bars. Verify that the strap is symmetrically positioned with no gaps between the strap and the lugs.

Is an aftermarket strap compatible with reference 1343-0100?

Yes, any 20mm flanged strap is compatible with the Endeavour 1343-0100. Artisanal straps from Milano Straps are crafted specifically for this width and tested to precise tolerances. Always verify the 20mm lug width before purchase and confirm explicit compatibility with your retailer.

What is the average lifespan of a leather strap for this watch?

A quality leather strap (alligator, calf, cordovan) typically lasts 3 to 5 years with moderate daily wear, provided regular maintenance is observed. Exposure to moisture, perspiration, and UV rays accelerates ageing. Rubber or NATO straps resist degradation longer (5–7 years), whilst vegetable-tanned leather can exceed 5 years whilst developing an engaging patina. Rotating between multiple straps extends the lifespan of each.
