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

The Oris Artelier 01 781 7703 4351-07 5 21 70FC features a lug width of 21.00mm. This measurement is specific to this model and should not be confused with other references that may use 20mm. Verify the distance between the inner margins of the case lugs to ensure compatibility before ordering an aftermarket strap.

The ideal strap depends on your intended use. For formal occasions, we recommend dark cognac alligator with a gold-coloured deployante, which provides noble contrast with the blue dial. For daily wear, vegetable-tanned calfskin in medium brown offers comfort and develops a natural patina over time. NATO straps remain a legitimate choice for sporty-casual contexts, whilst FKM rubber is reserved for specific activities such as water sports.

To change the strap, use a spring bar tool to gently push the pins from the opposite side relative to the old strap. Extract the pin completely and remove the strap. Insert the pin into the new strap, aligning it with the case lugs, then press until you hear a click. Verify that the pin is fully seated before wearing the watch.

Yes, the Artelier with 21mm lugs is fully compatible with quality artisanal straps. MilanoStraps offers a selection of leather straps (alligator, shell cordovan, vegetable-tanned calfskin) and NATO fabrics manufactured specifically for this lug width. Always ensure the strap has been constructed for 21mm width to guarantee precise and stable mounting.

Leather strap durability depends on material type, usage, and care. Quality alligator or shell cordovan with vegetable tanning can last 5-8 years with daily wear, or 10+ years when rotated with other straps. Standard calfskin typically lasts 3-5 years. The patina that develops over time is characteristic of good-quality leather and increases its aesthetic value. Avoid prolonged exposure to direct sunlight and humidity to maximise longevity.
