Frequently asked questions

What is the lug width of the H. Moser & Cie Endeavour 1810-1203?

The lug width of the H. Moser & Cie Endeavour 1810-1203 is 20 mm. This measurement is critical for strap compatibility and is calculated by measuring the distance between the inner lug pins, perpendicular to the dial.

Which strap is most suitable for the H. Moser & Cie Endeavour 1810-1203?

We recommend an alligator strap in dark tones (dark brown, burgundy, black) or vegetable-tanned calf leather that develops a unique patina over time. These choices respect H. Moser & Cie's minimalist philosophy, emphasising manufacturing quality without competing with the watch. A synthetic textile NATO strap offers greater versatility with rapid changeover capability.

How do you change the strap on the H. Moser & Cie Endeavour 1810-1203?

The strap is changed by extracting the lug pins using a specialised tool (spring bar removal tool) or a pointed instrument. It is recommended to position the watch on a soft surface to avoid scratches. If you are not experienced, consult a jeweller or specialist such as Casati Milano to perform the operation with precision.

Is an aftermarket 20mm strap for the 1810-1203 compatible with other 20mm watches?

Yes, a 20 mm strap is generally compatible with any watch that has the same lug width. However, the shoulder profile, groove depth and leather thickness may vary slightly between our artisan straps and budget alternatives, affecting aesthetics and comfort.

How long does a leather strap last on the Endeavour?

An artisan-quality leather strap, exposed to normal wearing conditions, has an average lifespan of 4-6 years. Vegetable-tanned calf leather wears more slowly and develops a fascinating patina. Alligator, being more durable, can last 8-10 years or longer. Wear depends on frequency of use, humidity and maintenance.
