Strap for Endeavour Centre Seconds, Rose Gold, Fumé Dial

The H. Moser & Cie Endeavour 1343-0105 features a lug width of 20mm, measured from the centre of one lug pin to the other. This standard was developed by Moser to maintain perfect proportions between the 40.8mm case and the lug structure. Only straps specifically dimensioned at 20mm will ensure correct fitment and preserve the architectural elegance of the timepiece.

The optimal choice depends on personal aesthetic philosophy. Shell Cordovan in dark brown vegetable tanning represents the pinnacle of compatibility: its natural chromatic depth dialogues perfectly with rose gold. A European calf leather with an initiated patina in cognac-brown tones is the ideal foundation for daily wear. For conscious contrast, absolute black functions exclusively on luminous Shell Cordovan, never on flat leather. Indigo and Prussian blue tones offer sophisticated modulation.

Use a spring bar removal tool to compress the spring bars positioned at the sides of each lug pin. Once the springs are depressed, the old strap removes easily. Insert the new strap by aligning it with the pins and press the spring bars until they click into position. Always verify that the strap is secure before wearing the watch. For an Endeavour of this calibre, we recommend having the operation performed by professionals at Casati Milano.

Yes, numerous high-quality artisanal straps are compatible with the 20mm lug width. Milanostraps.it offers a comprehensive collection of 20mm straps in vegetable-tanned leather, Shell Cordovan, and artisanal NATO ribbons, all precisely dimensioned for the Endeavour and other watches with the same lug width. Always verify the 20mm specification before purchase to ensure compatibility.

The lifespan of a leather strap depends on usage intensity and material quality. Premium vegetable-tanned leather, as used in artisanal straps, typically lasts 3-5 years with daily wear. The patina that naturally develops over time enhances aesthetic character. Factors such as perspiration, sun exposure, and humidity accelerate ageing. Shell Cordovan, due to its superior density, can last 7-10 years. Regular maintenance—cleaning and conditioning with specific creams—significantly extends longevity.
