Strap for Artelier Chronometer Date 40.5 Stainless Steel / Black

The lug width is 21 millimetres. This measurement is taken by positioning a ruler between the centre of the upper lug and the centre of the lower lug when the watch is placed flat on a surface. It is the most common dimension in contemporary luxury watchmaking.

The ideal strap depends on intended usage: dark brown alligator provides formal elegance with the grey-white dial; vegetable-tanned calf with aged patina offers Milanese artisanal character; navy NATO maintains everyday versatility; charcoal rubber is perfect for humid environments or casual sports wear.

The Oris Artelier features straight lugs with removable spring bars. Use a dedicated tool to remove the spring bar, extract the old strap, position the new strap aligned with the lug holes, and reinsert the spring bar until it clicks into place. Apply controlled pressure to ensure proper positioning.

Yes, absolutely. Any strap with a 21-millimetre lug width is fully compatible with the 01 637 7544 4064-07 5 21 49 model. What matters is verifying the total strap length (upper pad plus lower pad) to ensure correct positioning on the wrist.

A vegetable-tanned leather strap, subjected to moderate daily use, typically lasts 3–5 years before replacement becomes necessary. Natural aging—colour shift and patina development—is desired and does not compromise structural function. Rubber straps require replacement every 2–3 years.
