Strap for Artelier Hand Winding Small Second 40 Stainless Steel - Yellow Gold / Silver

The lug width of the Oris Artelier 01 396 7580 4351-07 5 21 05 is 21mm. This measurement indicates the distance between the centres of the two lugs (case end pieces) where the strap attaches. A 21mm dimension requires careful selection of compatible straps, as it does not fall within the most common mass-market sizes.

Strap choice depends on intended use. An alligator leather with vegetable tanning and natural patina emphasises the Artelier's formal elegance and suits structured occasions. Tanned calf offers predictable ageing and soft texture conveying craftsmanship. A cotton NATO renders it versatile and casual. A fluoroelastomer rubber serves those alternating environments and climates. All these materials align coherently with the Swiss timepiece's understated aesthetic.

Strap replacement is straightforward and requires no special tools. The case features spring bars (spring-loaded bars) already fitted: insert a thin implement (a dedicated spring bar tool or even a hairclip) into the small lateral hole of the spring bar, apply pressure to retract the spring, then extract the old strap end from the lugs. Repeat on the other side, then align the new strap's attachment points in the lugs and release the spring bars. The operation takes less than a minute.

Yes, entirely. Artisan-quality aftermarket straps are compatible with any watch featuring 21mm lug width, regardless of brand. Indeed, replacing the original strap with a handcrafted Italian model permits superior materials (selected alligator, vegetable tanning, shell cordovan) and customisation impossible in industrial manufacturing. The spring bars remain unchanged, ensuring trouble-free fitting.

A natural leather strap with vegetable tanning, used daily on an Oris Artelier, typically lasts 3 to 5 years before replacement becomes necessary. Longevity depends on ambient humidity, sun exposure, cleaning frequency, and initial leather quality. Vegetable-tanned alligator ages more slowly than calf, developing patina rather than deteriorating. Regular maintenance—cleaning with damp cloth, occasional conditioning with natural waxes—extends strap lifespan by 1 to 2 years.
