Strap for Artelier Date 40.5 Stainless Steel / Silver

The lug width of the Oris Artelier 01 733 7670 4071-07 1 21 73FC is 21mm. This measurement represents the distance between the spring bar pins that hold the strap. To verify, use a calliper and measure the internal space between the two spring bars—it should be exactly 21mm. A lug width of this specification requires a strap specifically dimensioned for 21mm and ensures complete compatibility with our artisanal 21mm strap collection.

For the Artelier 40.50mm, we recommend a quality leather strap—leather with vegetable tanning, calf or alligator—to emphasise the dressy character. A strap in hammered or fine-grain leather, typically 1.4–1.6mm thick, creates harmonious proportions with the case. Alternatively, a cotton-polyester NATO or FKM rubber strap suits more operational use. Avoid chunky or overtly sporty straps: the Artelier demands measured elegance, not ruggedness.

Strap replacement involves removing the spring bars with a dedicated spring bar tool. Position the tool on the spring from the back of the case, apply downward pressure to release the pin, then extract the old strap. Insert the new 21mm strap by aligning the holes with the spring bars, then reposition the springs until they click into place. For a safe operation without risk of scratching, we recommend visiting a professional watchmaker.

Yes, any artisanal strap with a 21mm lug width is completely compatible with this model. Always verify that the strap is dimensioned with 21mm lugs: the case diameter (40.50mm) and spring bar thickness pose no restrictions. An aftermarket strap allows you to vary the watch's style without technical compromise, maintaining fit and security.

A quality leather strap with vegetable tanning or alligator leather lasts 2–3 years with moderate daily use, up to 5–7 years if worn occasionally. Durability depends on exposure to perspiration, water and sunlight: humid environments (shower, swimming pool) degrade the fibre more rapidly. Patina and age marks are natural and enhance character. To maximise longevity, dry the strap after water contact and apply nourishing balm every 6–8 months.
