Strap for Constellation Co-Axial 35.5 Stainless Steel / Yellow Gold / Diamond / Silver / Olympic Beijing 2008

The lug width is 20 millimeters. This measurement represents the distance between the spring bars that connect the strap to the case. It is essential to choose a strap of exactly 20mm to ensure precise fitting without lateral play.

Alligator is the ideal material for this two-tone model: the fine grain enhances the case geometry and the gold-steel contrast. Excellent alternatives are vegetable-tanned calf for a natural patina, or shell cordovan for sophisticated luster. The choice depends on daily use and personal aesthetic preference.

Changing the strap requires a specific tool (spring bar tool) to loosen the spring bars without damaging the case. Insert the tool into the small lateral slots of the return spring, push downward, and remove the spring bar. Insert the new strap by aligning the holes and reinsert the spring bar until it stops. If you are not experienced, the Casati Milano atelier offers this service by appointment.

Yes, any 20mm strap is compatible. Milano Straps artisanal straps are made specifically for this lug width and offer superior quality compared to generic straps. You can customize material, color, initials, and buckle type according to your preferences.

A quality leather strap, with vegetable tanning or alligator, typically lasts 3 to 7 years depending on daily use. Premium materials such as shell cordovan can last up to 10 years. The natural aging of leather, with the development of a patina, is part of the charm of the artisanal strap and does not indicate premature wear.
