Strap for Endeavour Centre Seconds Red Gold / Midnight Blue Original

The lug width of the H. Moser & Cie Endeavour 1200-0401 is 20 millimetres. This dimension is measured as the net distance between the axes of the two spring bar pins where the strap attaches to the case. Precise measurement with a digital calliper is essential to ensure the strap fits perfectly without lateral movement.

The most suitable material depends on usage and personal preference. Alligator with fine grain dialogues elegantly with the aesthetic purity of the fumé dial, developing patina over time. Calf leather with vegetable tanning offers softness and natural ageing, whilst shell cordovan guarantees density and enduring brilliance. For more dynamic contexts, robust NATO or FKM rubber represent practical choices without aesthetic compromise.

The strap is changed using a specialised spring bar removal tool. Gently remove the internal spring of one pin, extract the old strap, then insert the new one between the pins, ensuring the spring positions correctly in its seat. The operation requires precision to avoid damaging the pins. Many watchmakers and specialist retailers offer this service free of charge.

Yes, provided it strictly respects the 20mm lug width and is manufactured by artisans with consolidated experience. A quality aftermarket strap, with meticulous construction and certified materials (alligator, vegetable-tanned calf, shell cordovan), guarantees superior durability and aesthetic to many originals, whilst offering greater customisation and lasting value.

A quality leather strap (alligator, calf, shell cordovan) under regular use lasts on average 3–5 years before requiring replacement. Durability depends on usage frequency (daily vs. occasional), exposure to moisture and perspiration, and maintenance care (timely drying, periodic conditioning). A rubber or NATO strap, thanks to chemical and mechanical resistance, can last 5–10 years or beyond.
