Frequently asked questions

What is the lug width of the H. Moser & Cie Endeavour 1346-0101?

The lug width of the H. Moser & Cie Endeavour 1346-0101 is 20mm. This measurement is taken by placing callipers on the inside of the lugs, measuring the distance between the two pins that attach the strap to the case. A strap with an incorrect lug width not only compromises the watch's aesthetics but requires additional adjustment work.

Which strap is recommended for the Endeavour 1346-0101?

For the H. Moser & Cie Endeavour 1346-0101, an alligator strap in dark brown or black is recommended, as it complements the rose gold case without competing with the smoked dial. Italian vegetable-tanned calf leather is a worthy alternative, whilst shell cordovan delivers a more dramatic character. For active use, NATO or FKM rubber straps provide protection without compromising elegance.

How do you change the strap on a watch with integrated lugs?

The H. Moser & Cie Endeavour 1346-0101 features integrated lugs (non-spring), meaning the strap cannot be removed simply by pressing the pins. A specialist watchmaker is required to use specialized tools to remove the pins and install the new strap. DIY attempts are strongly discouraged to avoid case damage.

Is there an aftermarket strap compatible with the 1346-0101?

Yes, Milano Straps offers a complete range of artisanal straps in 20mm lug width, compatible with the H. Moser & Cie Endeavour 1346-0101. All straps are crafted with premium materials (alligator, calf, shell cordovan, NATO) and can be personalised on request. The artisanal construction quality guarantees durability comparable to the original.

How long does a leather strap last on a luxury watch?

A high-quality leather strap (alligator or vegetable-tanned calf) has an estimated lifespan of 3 to 5 years with regular daily use, provided proper maintenance: avoid prolonged water contact, protect from excessive sun exposure, and clean periodically with a soft cloth. Alligator tends to outlast ordinary calf. Shell cordovan can exceed 5 years whilst maintaining excellent aesthetic and tactile properties.
