Frequently asked questions

What is the lug width of the H. Moser & Cie Endeavour 1345-0500?

The H. Moser & Cie Endeavour 1345-0500 features a lug width of 20 millimetres. This measurement represents the construction standard for case diameters between 36 and 42 millimetres. The internal depth between the terminals permits reliable compatibility with strap widths ranging from 19.5 to 20.5 millimetres. To verify compatibility, insert the strap terminal into the lug slot and confirm the absence of lateral play.

Which strap material is recommended for the Endeavour 1345-0500?

Material selection depends upon aesthetic and functional preferences. Alligator proposes sophisticated contrast to the titanium lunar-grey case, with characteristic grain that captures light. Vegetable-tanned calf offers natural patina evolution and tactile adaptation to the wrist. NATO straps in nylon address versatility requirements, particularly in sporting contexts. FKM rubber represents the optimal solution for marine or climatically aggressive environments. Casati Milano offers bespoke solutions tailored to individual material preferences.

How does one replace the strap on the Endeavour 1345-0500?

Strap replacement is a straightforward procedure requiring a dedicated spring bar tool. Position the timepiece with lugs facing upward, insert the tool's fine end into the small hole on the retaining spring, apply gentle downward pressure to liberate the terminal from the lug, then remove the previous strap. Insert the new strap, aligning the terminal and pressing downward until the retention 'click' occurs. Should the procedure prove uncertain, Casati Milano artisans execute the change with professional precision.

Is an aftermarket strap compatible with the Endeavour 1345-0500?

Yes, any strap with a 20 millimetre lug width is compatible with the Endeavour 1345-0500. Milano Straps are specifically engineered for this standard width and present construction quality comparable to luxury timepieces. Prior to dispatch, each strap undergoes compatibility verification. Availability includes fine leathers (alligator, calf), textile NATO straps and premium elastomers, ensuring aesthetic and functional versatility.

What is the average lifespan of a leather strap for this watch?

Leather strap longevity depends upon wear frequency, climatic conditions and maintenance. A vegetable-tanned calf strap, worn daily under normal conditions, presents a useful life of 24-36 months. Alligator, being denser hide, may reach 48-60 months of use. The natural patina development constitutes part of the aesthetic fascination. To extend longevity, dry the strap following moisture exposure, avoid prolonged direct sunlight, and periodically condition the leather with purpose-designed maintenance products. Casati Milano provides bespoke maintenance guidance upon purchase.
