Strap for Endeavour Perpetual Moon Red Gold / Vantablack / Only Watch 2019

The lug width of the 1801-0401 is 20mm. This measurement is essential for selecting compatible watch straps. You should measure the space between the suspension pins on the case lugs, ensuring that any replacement strap matches this technical standard precisely.

For the Endeavour 1801-0401 with 42mm red gold case, we recommend alligator in cognac or dark brown for maximum formal elegance, or vegetable-tanned calf leather for natural patina development over time. Silk-synthetic NATO straps provide functional versatility, whilst structured rubber offers compelling contrast while maintaining aesthetic dignity.

To change the strap, obtain a spring bar removal tool. Position the watch on a stable surface, carefully use the tool to compress the suspension pins slightly, and slide the old strap out of the lugs. Insert the new 20mm strap, aligning the holes properly, release the pins and verify they are securely seated. Simple procedure but requires care to avoid scratching the case.

Yes, you may fit aftermarket quality straps provided they respect the 20mm lug width specification. Artisanal leather, synthetic NATO, or rubber straps are fully compatible with the 1801-0401. Ensure the strap features removable bars and that the material is constructed to standards appropriate for the watch's value and aesthetic requirements.

A leather strap's lifespan depends on tannage type and usage patterns. High-quality alligator or vegetable-tanned calf strap typically lasts 3-5 years in regular daily use. Leather naturally ages, losing elasticity and developing patina. The red gold case of the 1801-0401 patinas similarly, so parallel ageing of strap and case creates coherent aesthetic continuity.
