Artelier 01 623 7582 4074-07 5 21 71FC— lug 21mm

The lug width of this model is 21mm. This measurement is crucial for selecting a compatible strap. Measure correctly by inserting a digital calliper between the lugs, checking both sides. Even a 1mm error results in straps that do not adhere properly to the case.

The best strap depends on usage and personal preference. For formal contexts, textured alligator with vegetable tanning or veal with natural patina respects the Artelier's restrained identity. For versatility, a cotton-wool NATO offers practicality and breathability. For humid environments, fluoro-elastometric rubber ensures structural integrity without permanent deformation.

Strap replacement is a simple operation: use a spring bar tool to compress the lug spring, then extract the metal pin from the hole. Position the new strap and verify that the lug engages fully in the holes before releasing pressure. Confirm that the strap adheres evenly on both sides of the case.

Yes, provided the strap has exactly 21mm lug width. Bespoke artisanal straps are often superior in construction quality and material compared to OEM straps. Always verify that the strap is compatible with the lug width before purchase.

Leather strap durability depends on tanning type and usage. A vegetable-tanned veal with natural patina lasts approximately 3-5 years with regular maintenance (cleaning, occasional conditioning). Structured alligator, more durable, can reach 5-7 years. Wear concentrates on the loop and buckle: these are the first points to show signs of failure.
