Frequently asked questions

What is the lug width of the H. Moser & Cie Endeavour 1200-1221?

The H. Moser & Cie Endeavour 1200-1221 features a lug width of 20mm. This measurement is determined by measuring the distance from the base of one lug to the opposite lug in a straight line perpendicular to the case. It is essential to verify this dimension before purchasing an aftermarket strap, as incompatibility can result in poor fit and undue stress on the lugs.

Which strap do you recommend for the 1200-1221?

For the Endeavour 1200-1221, we recommend shell cordovan in dark tones (brown, burgundy) for those who appreciate aesthetic evolution over time and natural patina development, or vegetable-tanned calf leather in neutral tones (pearl grey, hazelnut) for those preferring simplified maintenance. For sporty contexts or warm climates, vulcanised rubber with a grain finish offers practicality whilst maintaining sobriety. Avoid alligator or crocodile straps, which would communicate excessive formality relative to the case's minimalist character.

How do I change the strap on my H. Moser & Cie Endeavour?

Strap replacement requires removal of the spring bars located at the case's extremities. Use a dedicated spring bar tool to gently compress the internal spring, allowing extraction from the lug. Once both bars are freed, the original strap separates. Insert the new spring bars into the aftermarket strap, position it beneath the case, and push the bars into their seats until they click into place. This operation typically requires 5-10 minutes and no specialist knowledge.

Are 20mm aftermarket straps compatible with the 1200-1221?

Yes, any strap with a 20mm lug width is compatible with the H. Moser & Cie Endeavour 1200-1221, provided construction quality is adequate and the spring bars are stainless steel or gold. Milano Straps' offerings are tested for compatibility and finish coherence with the watch's aesthetic. We recommend verifying the respective width, as minor variations (19.5mm versus 20.5mm) may result in undesirable looseness or friction.

How long does a leather strap last on my Endeavour?

A quality calf leather strap (such as those offered by Milano Straps) with daily wear has an average lifespan of 3-5 years before replacement is required. Shell cordovan, owing to superior material density, may last 5-7 years. Longevity depends on factors including wear frequency, exposure to moisture, perspiration and direct sunlight. Proper maintenance—drying after rain, annual conditioning with natural wax—significantly extends useful life. The strap's value lies not only in durability but in the patina and aesthetic evolution it accumulates over time.
