Frequently asked questions

What is the lug width of the H. Moser & Cie Endeavour 1321-0400?

The lug width of the H. Moser & Cie Endeavour 1321-0400 is 20mm. This measurement represents the distance between the integrated lugs of the case and determines strap compatibility. The integrated lugs on the Endeavour model provide superior structural integrity compared to soldered lugs.

Which strap is recommended for the Endeavour 1321-0400?

For the Endeavour 1321-0400 in rose gold with smoked dial, we recommend chocolate brown alligator or vegetable-tanned calf leather. These materials enhance the warm reflections of the case and develop a noble patina over time. For a more sporty approach, a natural cotton NATO strap offers versatility whilst maintaining elegance.

How do I change the strap on this Moser model?

The integrated lugs on the Endeavour allow for relatively straightforward strap replacement. Using a dedicated spring bar tool and proceeding with care, it is possible to remove the tension bars and replace the strap. We recommend this operation be performed by professionals; Milano Straps offers installation service by appointment at the Casati Milano atelier.

Can I fit an aftermarket strap on a 1321-0400?

Yes, it is possible to fit aftermarket 20mm straps. Milan Straps artisanal straps are engineered to be fully compatible with the integrated lugs of this model. The quality construction of our straps guarantees robustness and longevity, complementing the excellence of the timepiece.

How long does a leather strap last on a watch like this?

The durability of a leather strap depends on material and usage. A high-quality artisanal alligator or vegetable-tanned calf, worn daily, maintains structural integrity for 3-5 years. Patina develops progressively, creating aesthetic character. Factors such as humidity, perspiration and sun exposure accelerate ageing; periodic maintenance significantly extends useful life.
