Strap for Constellation Co-Axial 41 Chronograph Double Eagle Yellow Gold / Champagne / Beijing 2008

The lug width of this model is 20mm. This measurement is determined by the distance between the removable spring bar attachments on the case and is essential to ensure compatibility with aftermarket straps. You can verify it by measuring with a digital caliper the internal distance between the upper and lower attachments at the center of the case.

Dark brown or hazelnut alligator is the most natural option: its elegant texture and fine grain create visual harmony with the gold. Alternatively, vegetable-tanned calf leather allows a patina to develop over time that reveals underlying layers of color, generating extraordinary aesthetic depth. For superior durability, burgundy shell cordovan offers a glossy appearance that elegantly contrasts with the matte finish of the gold.

The Constellation uses removable spring bar attachments. To replace the strap, identify the pins connecting the attachments to the case, gently remove them with an appropriate tool (spring bar tool), then disconnect the old strap. Insert the new 20mm lug width strap into the seat and reinsert the pins firmly. If you are unsure of the procedure, entrust the task to a qualified watchmaker to avoid scratching the case.

All straps with 20mm lug width are compatible. Online you will find a wide selection of <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-20mm">20mm straps</a> ready for shipment, customizable in sizes, initials and thread color. The Casati Milano atelier also creates bespoke straps tailored to your specifications with personal leather selection, WhatsApp updates and 18-month warranty.

The durability of a leather strap depends on the type of leather, the intensity of use and maintenance. High-quality alligator resists 3-5 years with daily wear, vegetable-tanned calf 2-4 years, shell cordovan up to 6-7 years thanks to its superior resistance. To extend its life, avoid prolonged exposure to humidity, do not forcibly bend the lug width and occasionally apply leather-specific conditioners. The patina that develops naturally is a sign of noble aging, not deterioration.
