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

The lug width of this model is 21 mm. This constructive specification results from the geometry of the 40.50 mm case and is essential when purchasing compatible straps. Correct measurement is performed by measuring the distance between the inner lugs (the pins that support the strap) using a digital calliper.

This depends on intended use. For formal environments, an alligator strap with vegetable tanning offers elegance and develops natural patina over time. For robust daily wear, vegetable-tanned calf leather ages beautifully. For sporting contexts or humid climates, ballistic nylon NATO or vulcanised rubber (FKM) provide waterproofing and practicality. Your choice should balance aesthetics with functional requirements.

The strap is held by two lugs (spring bars) that pass through the lateral holes in the case. Using a spring bar tool, gently compress the internal spring of the lug and extract the bar from the case. The old strap then releases. Insert the new 21 mm strap by aligning the holes with the bars and pressing until you hear the spring click into place. The operation requires care to avoid damaging the lugs.

Any strap with a 21 mm lug width is compatible. milanostraps.it offers bespoke straps in alligator, calf, cordovan, rubber and NATO fabric, all crafted to this specification. Compatibility is guaranteed by correct lug measurement; always verify that the strap is explicitly labelled as 21 mm to avoid incorrect sizing (20 mm would be loose, 22 mm too tight).

Durability depends on tanning method and daily use. A vegetable-tanned leather strap worn daily but not under excessive stress can last 3-5 years whilst maintaining functionality, though patina evolves. Alligator leather, being denser and more resistant, exceeds 5 years. Pressed alligator (less expensive) lasts 2-3 years. Primary wear concerns the material around the lugs and stitching; the buckle (if steel deployant) remains essentially permanent. Store the strap away from humidity and direct sunlight to significantly extend its life.
