Strap for Artelier Date 40.5 Stainless Steel - Yellow Gold / Silver

The lug width (or lug distance) of the Oris Artelier 01 733 7670 4351-07 5 21 70FC x is 21 mm. This measurement represents the distance between the two lug attachments on the case and is essential for compatibility with aftermarket and artisanal straps. Measuring the lug width accurately with a digital calliper positioned perpendicular to the lugs is fundamental to select the correct compatible strap.

Four primary options are recommended for the Artelier: a vegetable-tanned leather strap for those seeking natural patina development and chromatic evolution over time; an alligator strap for those preferring a defined grain texture and visual stability; a natural rubber strap for intense and humid environments with superior water resistance; a NATO strap for chromatic versatility and quick replacement capability. Selection depends on use case and personal aesthetic preferences regarding temporal evolution.

Strap replacement is performed by removing the spring bars from the lug attachments. Using a dedicated spring bar removal tool, insert the tip into the lateral slot of the bar until release. Once the bars are extracted from one side, the strap separates from the case. Insert the bars into the new strap and secure them in the attachments until the locking click is heard. This operation is recommended at an authorised service centre if appropriate tools are unavailable.

Yes. The 21 mm lug width permits compatibility with a broad range of quality artisanal aftermarket straps. Straps offered by milanostraps.it, specifically curated for this lug width, guarantee superior constructive quality and longevity compared to standard straps. Always verify that the strap is certified for 21 mm lug width prior to purchase.

A quality leather strap, manufactured with vegetable tanning or alligator leather, has an average lifespan of 3-5 years under regular use and ordinary maintenance conditions. Longevity depends on use intensity, humidity exposure and periodic application of conditioning products. A vegetable-tanned strap tends to age visually whilst maintaining structural functionality. A natural rubber strap exhibits superior durability in humid environments or intense sports, reaching 5-7 years with minimal maintenance.
