The Endeavour 1342-0101, seen from the bench

The H. Moser & Cie Endeavour 1342-0101 is a 40.80mm white gold timepiece from the independent Schaffhausen manufacture. It features the in-house HMC 342 caliber with hours, minutes, seconds, big date, and power reserve indicator. The smoke-dial with dark blue to black gradient contains no logos or printed indices. The 20mm lug width maintains proportional balance with the case diameter and ensures optimal strap interface without binding or excessive tension.

Frequently asked questions

What is the lug width of the H. Moser & Cie Endeavour 1342-0101?

The Endeavour 1342-0101 features a 20mm lug width, a dimension determined by the proportions of the 40.80mm case and the geometric design of the case lugs. This width ensures correct visual balance between case diameter and lug elements, maintaining constructive compatibility with the strap attachment system.

What is the best strap for the Endeavour 1342-0101?

For a watch of this formal simplicity, we recommend straps in alligator leather (pearl grey or white tones), vegetable-tanned calf in dark shades, or shell cordovan in bordeaux. Each choice should feature a metal deployant clasp in precious metal, aligned with the formal integrity of the watch and Schaffhausen manufacture.

How do I change the strap on this watch?

The strap is replaced by removing the spring bars located on both sides of the case using a spring bar tool. Gently extract the bar with the tool, and the previous strap slides out. Insert the new 20mm strap, reinsert the spring bar, and verify secure locking. If unfamiliar with the procedure, we recommend consulting a qualified watchmaker to avoid damage to the gold lugs.

Are there compatible aftermarket straps for the 1342-0101?

Yes, milanostraps.it offers a complete collection of handcrafted 20mm straps compatible with the Endeavour 1342-0101. All our models are crafted in Italy using selected materials (premium leather, alligator, shell cordovan) and can be personalised according to your aesthetic preferences.

How long does a leather strap last on this watch?

A quality vegetable-tanned calf or alligator strap typically lasts 3–5 years with proper maintenance (periodic cleaning, drying after perspiration exposure, avoiding prolonged humidity). The natural patina developing over time enhances visual beauty. To extend longevity, rotate straps and apply natural conditioners 2–3 times annually.
