Strap for Constellation Co-Axial 41 Chronograph Double Eagle Stainless Steel / Black / Bracelet

The lug width of the Constellation 1519.51.00 is 20mm. To measure correctly, remove the original strap and use a digital caliper to measure the distance between the two inner lugs of the case. This measurement is critical to avoid misalignment or straps that are too wide.

The choice depends on usage: for maximum formality, a vegetable-tanned alligator in brown or black tones enhances the midnight blue dial and chrome lugs. For daily versatility, a Hermès calf leather in burgundy or chocolate offers softness and natural patina. For outdoor-sporty wear, a grey or blue NATO maintains elegance while reducing stiffness.

The Omega Constellation 1519.51.00 features a strap with 20mm lug width and standard spring bars. Use a dedicated tool to remove the spring bars from the original lugs, then insert the new ones into a compatible 20mm strap. If you are not experienced, the Casati Milano atelier offers a strap-change service with complete warranty.

Yes, provided it is compatible with the 20mm lug width. Many quality straps (alligator, calf, NATO) are available in this size. Always verify that the spring bars are removable and that the new strap respects the proportions of the 41mm case, avoiding aesthetic misalignment.

A quality leather strap (alligator or calf) lasts 3-5 years with conscious daily wear. Durability depends on ambient humidity, frequency of wear, and maintenance. Casati Milano straps come with an 18-month warranty and can be regenerated or replaced over time while maintaining the same 20mm lug width.
