Strap for Endeavour Flying Hours White Gold / Funky Blue

The lug width of the H. Moser & Cie Endeavour 1806-0200 is 20 millimetres. This specific width was precisely calculated by the Swiss manufacture to maintain proportional balance between the 42-millimetre case and the integrated original bracelet. Always verify the width using a digital calliper, positioning the probe between the case lug pins with the spring bars disengaged.

The optimal strap selection depends on intended usage and aesthetic preference. For formal-elegant contexts, alligator leather in cream white or grey talpa tones complements the white gold case and minimalist fumé dial. Vegetable-tanned calf leather represents the choice for collectors who appreciate patina evolution over time. For casual-sports wear, technical nylon NATO maintains ideal proportions without overloading the wrist. Fluoroelastomer rubber is recommended in marine or humid environments.

To change the strap, disengage the spring bar pressure mechanisms at the case lugs. Use a dedicated spring bar tool, inserting the flat blade into the lateral slot of the pin. Press downward to compress the spring and extract the pin. Repeat on the opposite side. To install the new 20mm strap, align the holes with the pins and press until the spring locks into position. Verify that the strap is parallel to the case.

Yes, aftermarket-compatible straps can be used provided they strictly respect the 20-millimetre lug width specification. Milano Straps supplies straps calibrated to this exact width, available in alligator, calf, NATO, and rubber. Using aftermarket straps does not compromise Moser warranty if the change is executed without damaging the pins or case lug seats.

Leather strap durability depends on usage frequency, solar exposure, and ambient humidity. Under normal wear conditions (5-7 days weekly), a high-quality artisanal alligator strap lasts between 4 and 6 years before visible wear appears at edges and pass-through holes. Vegetable-tanned calf tends to wear slightly faster (3-5 years) due to lower fibre density, though the patina developed is considered an aesthetic asset. Rotating between multiple straps significantly extends overall lifespan.
