Strap for Artelier Date 40 Stainless Steel - Rose Gold / Silver

The lug width of the Oris Artelier 01 733 7591 6351-07 5 21 70FC is precisely 21 millimetres. This is a fixed construction parameter: the lugs of the case are separated internally by exactly 21mm, and only straps dimensioned for this measurement will fit without lateral play or binding. Verify using a digital calliper or standard ruler before purchasing.

For the stainless steel and rose gold case with black lacquered dial, shell cordovan is the most refined aesthetic choice, owing to its characteristic grain that engages visually with the case metals. Black vitello with vegetable tanning offers a neutral and practical alternative. NATO nylon straps in dark grey or black provide a technical, reversible option ideal for intensive daily use. Natural vulcanised rubber is recommended for humid environments or technical applications.

Strap replacement requires a specialised tool: a spring bar remover or push pin suitable for the lug pin diameter (typically 1.5–1.8mm). Position the remover from beneath the lugs, push the pin horizontally until extraction, remove the old strap, insert the new strap into the lugs, and reinserting the pin from the opposite side. Work on a soft surface (magnetic mat) to prevent loss of spring bars.

Yes, any aftermarket strap with a 21mm lug width is dimensionally compatible. Build quality varies significantly, however. Vegetable-tanned leather straps with precision keepers and buckles maintain the watch's aesthetic integrity. NATO nylon in high denier (1000–1200) ensures durability. Verify that the buckle or deployante finish matches the case material—rose gold or satin steel.

Leather strap longevity depends on usage intensity, ambient humidity, and leather construction quality. Shell cordovan or medium-quality vitello, with moderate daily use, maintains structural integrity for 2–3 years. Shell cordovan ages more slowly than vitello, developing patina without premature deterioration. Periodic maintenance (soft-cloth cleaning, annual conditioning with leather-specific balm) significantly extends lifespan. Dry environments favour durability.
