Strap for Artelier Date 40 Stainless Steel / Black / Bracelet

The lug width of this model is 21 millimetres. This dimension is measured from the left lug hole to the right lug hole, perpendicular to the case plane. Compatible straps must be 21 mm wide to mount correctly on the case lugs without leaving gaps or obscuring the lug design.

For this classic dress watch, we recommend alligator leather in cognac or black for formal occasions, or vegetable-tanned calf for appreciating natural aging. For versatility, a tightly-woven NATO maintains elegant proportions without sacrificing practicality. Your choice depends on intended use: formal requires alligator, daily wear benefits from calf, sport-casual prefers NATO.

Use a spring bar tool or similar implement. Position it underneath the lug, gently lift the elastic pin securing the old strap, and extract it completely. Insert the new strap into the lug slots, ensuring the elastic pin aligns correctly, then press until you feel a click. Verify the strap is secure before wearing the watch.

A naturally-tanned vegetable leather strap typically lasts 3-5 years with daily wear, varying based on usage intensity, ambient humidity, and care. Alligator tends to outlast calf due to its stronger leather structure. Longevity extends significantly if the strap is removed each evening and if the watch avoids excessive water or perspiration exposure. Our vegetable-tanned leather straps age beautifully, developing characteristic patina.
