FAQ

What is the lug width of the H. Moser & Cie Endeavour 1343-0107?

The H. Moser & Cie Endeavour 1343-0107 features a lug width of 20 millimetres. This dimension is standard for watches with a 40.80mm case and ensures harmonious proportions between the case and the strap. To verify compatibility, measure the distance between the two lugs positioned on the sides of the case: the value must correspond exactly to 20mm.

Which strap is most suitable for the Endeavour 1343-0107?

For the Endeavour 1343-0107 in rose gold, we recommend alligator leather in chocolate brown or black, or calf leather with vegetable tanning that develops a natural patina over time. These materials complement the watch's sophistication whilst maintaining perfect visual balance. For those seeking versatility, a dark grey nautical rubber strap represents a modern and practical choice without aesthetic compromise.

How do I change the strap on my H. Moser & Cie Endeavour 1343-0107?

Strap replacement is performed via the spring bars that secure the strap to the case lugs. Use a dedicated tool (spring bar tool) to compress the spring bar and release it from its seat. Remove the previous strap, insert the new one by aligning the spring bars with the lugs, and release the tool so that the spring bar locks completely. For valuable watches such as the Endeavour, we recommend having the operation performed by a qualified service centre.

Are Milano Straps' straps compatible with the reference 1343-0107?

Yes. Milano Straps offers a comprehensive collection of straps in the 20mm dimension, exactly compatible with the Endeavour 1343-0107 lugs. All available models (alligator, calf, NATO, rubber) are developed to artisanal quality standards and ready for shipment. Online customisation allows you to select the specific material, colour and finishes for your watch.

How long does a leather strap last on a watch like the Endeavour?

The lifespan of a leather strap depends on the intensity of use and the quality of the material. Superior quality leather such as alligator or vegetable-tanned calf, if properly maintained (drying after moisture exposure, protection from direct sunlight), offers a longevity of 3-5 years with moderate daily wear. More robust rubber nautical straps significantly extend this duration. Milano Straps provides personalised consultation to help you choose the material best suited to your lifestyle.
