Strap for Artelier Complication 40.5 Stainless Steel / Silver

The lug width measures precisely 21 mm. This dimension is specific to this model and ensures optimal proportion between the 40.50 mm case and the strap. To verify compatibility with a new strap, measure the distance between the internal case attachments using a digital calliper.

The ideal strap depends on intended use. For formal elegance we recommend dark-toned alligator or shell cordovan. For daily versatility, calf leather with vegetable tanning in brown tones. For technical or sports contexts, FKM rubber or dense cotton NATO strap. All materials must feature a compatible 21 mm lug width.

Remove the watch and position it face-down on a soft surface. Locate the two spring bars that pass through the lugs. Using a specialised tool or sewing needle, push the bar inward to extract it completely. Remove the old strap and insert the new one, ensuring perfect alignment before reinserting the spring bar. Verify that the bar is fully inserted on the opposite side.

Yes. MilanoStraps offers a collection of artisanal straps for 21 mm lugs crafted in premium leather, technical rubber, and fine textiles. Each strap is verified for precision tolerances of ±0.5 mm and completed with stainless steel spring bars. Items are available for immediate dispatch and customisable upon request through the Casati Milano atelier.

A premium leather strap (calf, alligator, shell cordovan) typically lasts 3–5 years with daily wear. Durability depends on tanning method, cleaning frequency, and atmospheric exposure. Vegetable-tanned leather tends to age better, developing characteristic patina. FKM rubber maintains elasticity for 5–7 years before requiring replacement.
