Strap for Artelier Chronometer Date 40 Stainless Steel / Silver / Bracelet

The lug width measures 21 millimetres. This dimension is measured between the outer edges of the case lugs and determines compatibility with aftermarket straps. Accurate measurement is essential before ordering a strap to ensure proper fit and avoid incompatibility issues.

The optimal strap depends on your lifestyle. A vegetable-tanned leather develops natural patina and timeless elegance. For greater sophistication, alligator leather offers distinctive texture. If versatility is your priority, a fabric NATO allows rapid changes and performs across any context. Rubber is the contemporary choice, ideal if you alternate the watch between formal and active occasions.

Remove the strap by extracting the spring bars using a dedicated tool (spring bar tool). Position the watch on a stable surface, locate the steel pin running through the lugs, insert the tool on both sides to compress the internal spring, and slide the pin downward. Reverse the process to install the new strap. If unfamiliar with the procedure, consult a professional.

Yes, provided the strap is compatible with the 21-millimetre lug width. Quality aftermarket straps match the precision standards of original models whilst offering greater aesthetic customisation. MilanoStraps curates a selection of 21mm straps in leather, NATO, and rubber—all tested for compatibility and durability.

A quality leather strap typically lasts 3–5 years with daily wear. Longevity depends on the tanning method (vegetable or vegetable-synthetic), moisture exposure, and proper maintenance. Vegetable-tanned leather ages more nobly, developing patina, whilst treated leather offers greater water resistance. Rotating between multiple straps significantly extends overall lifespan.
