Strap for Endeavour Perpetual Moon Stainless Steel / Vantablack Concept

The lug width of the H. Moser & Cie Endeavour 1801-1200 is 20 millimetres. This measurement must be verified precisely by positioning a calliper on the inner shoulders of the case, from lug to lug, to ensure correct fitment of any aftermarket strap.

Anthracite grey alligator leather represents the most sophisticated pairing for this timepiece: its natural grain dialogue perfectly with the minimalist smoked dial. Alternative noble options include wine-coloured shell cordovan or vegetable-tanned calf in bordeaux tones. Selection depends on intended use: alligator for formal occasions, vegetable-tanned calf for daily wear and vintage ageing.

The strap is changed using a dedicated tool (spring bar tool) to compress the two spring bars that secure the strap to the lugs. Insert the tool into the lateral gaps, remove the old strap by compressing both spring bars, then align the new strap's holes with the lugs and release the spring bars. The operation requires delicate handling to avoid marking the case.

Yes, any strap with a 20mm lug width is fully compatible. Milano Straps provides bespoke straps in noble leathers (alligator, shell cordovan, vegetable-tanned calf) and technical models (NATO, rubber) already dimensioned at 20mm, ready for installation without modification.

A noble leather strap subjected to daily wear typically reaches 3–5 years of service before structural degradation occurs due to flexion and humidity exposure. Vegetable-tanned leather develops natural patina and improves aesthetically over time. Factors such as humid climate, frequent perspiration, and inadequate drying accelerate wear. A well-maintained strap (kept dry, stored in controlled environments) can last up to seven years.
