Strap for Master Collection 44 Chronograph Stainless Steel / Black-Roman / Alligator XL

The lug width is 22mm, measured between the outer edges of the case lugs. A compatible strap must feature 22mm x 20mm lugs (standard internal dimension).

For this 44mm chronograph, we recommend alligator in vegetable tanning, calf leather, or shell cordovan. Alligator offers natural patina and durability; calf leather provides uniform texture and colour gradations; shell cordovan delivers organic lustre. Avoid overly thin straps (< 3.5mm) that would disrespect the case's proportions.

Use a spring bar tool to remove the spring bar pins from the case lugs. Position the tool's tip into the pin hole, gently push inward to compress the spring, then withdraw the strap. Repeat on the second lug. Reverse the procedure to install the new strap.

Yes, the L2.859.4.51.8 is fully compatible with quality aftermarket straps featuring 22mm lugs. Verify the strap is constructed with 3.5–4mm premium leather and robust lugs. Milano Straps offers a curated selection of 22mm straps customisable specifically for this model.

Longevity ranges from 3 to 8 years depending on use, climate, and care. Superior vegetable-tanned leathers or alligator can endure considerably longer. The patina developing naturally over time is a desirable characteristic. We recommend protecting the strap from moisture and direct heat, and rotating alternatives periodically to extend useful life.
