Strap for Constellation Co-Axial 38 Yellow Gold / Champagne

The lug width of the Constellation 123.50.38.21.58.001 measures exactly 20 millimeters. This width is standard for 38mm watches and represents the critical compatibility parameter for selecting the correct strap. Measuring the lug width means positioning a caliper between the two metal terminals of the case perpendicular to the watch body.

Alligator represents the aristocratic choice for the Constellation in yellow gold: its regular grain and natural colors (cognac brown, black, tobacco) dialogue perfectly with the warmth of the metal. Shell cordovan with vegetable tanning is an excellent alternative for those desiring an evolving patina over time. Natural calf leather offers accessibility while maintaining aesthetic authenticity.

The strap is removed using a spring bar tool: insert the small metal rod into the lateral opening of the lug, lower the spring until releasing the pin. Once both ends are freed, the strap slides out. To install the new one, align the terminals with the case attachments and press the pin into position until the locking "click" is heard. Work on a soft surface (cloth) to prevent accidental scratches.

Yes, completely. The standardized lug width (20mm) allows the use of artisanal aftermarket straps of superior quality to the original bracelet. Straps in alligator, shell cordovan or calf with vegetable tanning offer aesthetic and practical advantages over integrated bracelets: quick swap capability, natural evolving patina, and personalized comfort based on season.

A quality leather strap (alligator, shell cordovan, calf with vegetable tanning) lasts an average of 3-5 years with regular use, and up to 7-8 years with proper maintenance and seasonal rotation. Durability depends on frequency of use, exposure to moisture/sweat and leather quality. Shell cordovan straps, being denser, tend to last longer. Periodic replacement is recommended not out of necessity, but to refresh the watch's aesthetic.
