FAQ

What is the lug width of the H. Moser & Cie Endeavour 1341-0103?

The Endeavour 1341-0103 features a lug width of 20mm. This dimension represents the classical standard for high-end watches with a 40.8mm case, ensuring compatibility with a broad selection of artisanal aftermarket straps. Measurement is performed by removing the integrated bracelet and measuring the internal space between the lugs using a digital calliper.

Which strap pairs best with the Endeavour 1341-0103 in rose gold?

For the Endeavour in rose gold, Mississippi alligator in chocolate brown represents the superior aesthetic choice: the fine grain interacts flawlessly with the fumé dial without creating visual competition. Alternatively, Italian calf leather with vegetable tanning develops a patina that ages harmoniously with the gold, whilst gummed rubber guarantees maximum practicality for daily wear without compromising design purity.

How do you change the strap on the H. Moser & Cie Endeavour 1341-0103?

To replace the Endeavour 1341-0103 strap, access the lateral lugs of the case using a spring bar tool. Remove the two elastic pins connecting the integrated bracelet to the lugs, then insert the new strap in the same position, ensuring the pins fully engage in their respective seats. This operation is recommended to be performed by official service centres or experienced craftspeople.

Are 20mm aftermarket straps compatible with the 1341-0103 model?

Yes, any strap with a 20mm lug width is entirely compatible with the Endeavour 1341-0103. Milano Straps offers a specialised collection of 20mm straps in leather (alligator, calf, shell cordovan), NATO and rubber, all manufactured to quality standards that respect the horological prestige of the watch.

How long does a leather strap last on a watch like the Endeavour 1341-0103?

The durability of a leather strap depends on material and usage patterns. Alligator and vegetable-tanned calf guarantee 3-5 years of daily wear, whilst shell cordovan, due to its fibre density, can exceed 7 years. Rotating between alternative straps (NATO, rubber) significantly extends the longevity of each strap, as no single element endures continuous stress.
