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

The lug width of the Omega Constellation 1514.20.00 is exactly 18mm. This measurement is fixed and non-negotiable: it represents the distance between the inner edges of the two lugs on the case. Any compatible strap must be exactly 18mm wide to fit correctly into the original slots without play or forcing.

Alligator leather tanned through vegetable tanning (black, dark brown, or havana) is the primary choice for this chronograph: the flat, regular grain of the leather elegantly contrasts with the steel case, while the natural patina developed over time adds character. Alternatively, Shell Cordovan in burgundy or red-brown offers a richer texture. For dynamic environments, a military-origin nylon strap maintains the authentic sports character of the model.

Changing the strap on the Constellation 1514.20.00 requires a specific tool (spring bar tool): position the thin end of the tool into the seat of the spring bar positioned horizontally beneath the lug, gently press inward to release the old strap, then insert the new 18mm strap by aligning the spring bar into the correct seats. Avoid sharp blows that could damage the case finish.

Yes, numerous 18mm straps are compatible with the Constellation 1514.20.00. Milano Straps offers a dedicated collection of handcrafted 18mm straps customizable in leather, color, and stitching type. The Casati Milano atelier also creates bespoke custom straps with personal leather selection and an 18-month warranty, an ideal option for those seeking a unique and durable strap.

A quality leather strap (alligator or Shell Cordovan in vegetable tanning) typically lasts 3-5 years with moderate daily use, provided regular maintenance: avoid prolonged water exposure, clean periodically with a soft dry cloth, and occasionally apply a neutral conditioner. Longevity can extend to 7-10 years with vegetable-tanned leather and proper storage. Handcrafted Milano Straps, backed by Casati Milano warranty, maintain structural functionality well beyond aesthetic finish.
