Strap for Artelier Date 40 Stainless Steel / Silver

The lug width of the Oris Artelier 01 733 7721 4051-07 5 21 34FC is 21mm. This measurement defines the internal distance between the two spring bars that secure the strap to the case. To verify it, use a digital calliper to measure the distance between the lug holes: it must be exactly 21mm. Inaccurate measurement risks strap slipping or aesthetic distortion of fit.

For the Oris Artelier 40mm in stainless steel, we recommend an alligator strap with vegetable tanning (thickness 4-4.5mm) to enhance its essential character, or Vachetta calf with fine grain for daily versatility. A natural rubber strap with subtle grain texture is the ideal choice for those seeking lightness and resistance to atmospheric agents. Avoid shell cordovan straps: the rigidity would make adjustment to the 21mm lug width difficult.

To change the strap: 1) use a spring bar tool (usually supplied with the watch); 2) position the tool in the recess beneath the lug; 3) push inward to eject the pin from its socket; 4) slide off the old strap; 5) align the new strap with the case holes and reinsert the pin. If unfamiliar with the procedure, entrust the task to Atelier Casati Milano to avoid case scratching.

Yes, any strap with 21mm lug width is compatible with the Artelier. Milanostraps.it offers handcrafted straps in leather, NATO and rubber specifically selected for harmonious proportions with a 40mm case. Compatibility is guaranteed by matching lug width; final quality depends on craftsmanship and materials chosen (vegetable tanning, alligator, calf, natural rubber).

The lifespan of a natural leather strap depends on frequency of use, climatic exposure and type of tanning. A vegetable-tanned alligator strap, well maintained, lasts 8-12 years with pleasing patina development. Vachetta calf resists 5-7 years before restoration is needed. Natural rubber maintains elasticity for 6-10 years. To prolong life, avoid prolonged water immersion and clean the strap monthly with a soft dry cloth. Atelier Casati Milano offers restoration services and spring bar replacement when necessary.
