The Endeavour 1342-0100, seen from the bench

The H. Moser & Cie Endeavour 1342-0100 is a 40.80mm rose gold case watch featuring the in-house HMC 342 manual-wind movement. The smoked lacquer dial displays hours, minutes, seconds, big date, and power reserve indicator with minimalist aesthetics. A 20mm lug width accommodates replacement straps, and the integrated bracelet creates a monolithic architecture characteristic of independent Swiss watchmaking.

Frequently asked questions

What is the lug width of the H. Moser & Cie Endeavour 1342-0100?

The Endeavour 1342-0100 features an integrated lug width of 20mm. This measurement is standard for the model and determines compatibility with aftermarket straps and bracelets. To verify, position a digital calliper between the two lateral lugs of the case: the internal distance must be exactly 20mm.

What is the best strap for the H. Moser & Cie Endeavour 1342-0100?

Alligator represents the ideal choice for enhancing the Endeavour's restrained aesthetic: its fine grain structure and deep black or burgundy tonality creates harmony with the smoked dial. Shell cordovan in cognac offers an elegant and durable alternative. For everyday versatility, vegetable-tanned calf leather in brown or tobacco shades allows natural patina development over time.

How do you change the strap on a 20mm lug width watch?

Use a spring bar removal tool to access the retention springs positioned at the strap extremities. Gently press the spring toward the watch centre to release it from the lug, then extract the strap. Reverse the process to install the replacement strap, ensuring both springs are fully engaged in opposite lugs.

Are aftermarket 20mm straps compatible with the Endeavour 1342-0100?

Yes, any strap with a 20mm width lug is technically compatible with the Endeavour 1342-0100, thanks to its integrated lugs that accept standard spring bars. However, we recommend selecting premium materials (alligator, shell cordovan, vegetable-tanned calf) to maintain aesthetic coherence with the Moser & Cie's construction excellence.

How long does a leather strap last on a 20mm lug width watch?

A premium leather strap (alligator, shell cordovan, vegetable-tanned leather) subjected to moderate use maintains structural integrity for 4-7 years. Longevity depends on usage frequency, climatic conditions, humidity exposure, and tanning quality. Regular maintenance—gentle cleaning, occasional conditioning, natural drying—significantly extends useful life.
