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

The lug width is 21.00 mm, measured between the inner lugs of the case. This dimension determines compatibility with any aftermarket strap; simply select straps specifically designed for a 21 mm lug width.

An alligator or vegetable-tanned calf leather strap represents the most harmonious choice: the natural grain of the leather dialogues perfectly with the brushed stainless steel case and the watch's inherent elegance. For daily wear, a conscious fabric NATO maintains versatility; for formal contexts, black calf with a stainless steel deployant buckle is ideal.

The strap is released via spring bars located at the extremities of the lugs. Using a spring bar tool, apply inward pressure to compress the spring, then slide out the old strap. Insert the new one by aligning the holes with the 21 mm lug and allow the spring to close automatically. You do not need to visit a watchmaker.

Yes, provided the strap is specifically designed for a 21 mm lug width. Always verify the declared width before purchase: undersized or oversized straps do not guarantee secure attachment. Italian artisanal brands produce excellent alternatives in leather, alligator, and shell cordovan with certified geometry for this measurement.

A quality leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts 3–5 years with moderate daily use. Longevity depends on UV exposure, ambient humidity, and frequency of wear. A strap used occasionally (2–3 times weekly) can exceed 7 years. Periodic maintenance (cleaning and conditioning) significantly extends useful life.
