Strap for Constellation Co-Axial 41 Chronograph Double Eagle Red Gold / Carbon / Rubber

The lug width is 20mm. This dimension is standard for this model and determines the choice of all compatible straps. To verify it, insert a digital caliper into the strap attachment points (the seats where the original strap was anchored) and measure the distance between the inner walls.

Vegetable-tanned alligator is the most noble choice for this model. The natural grain texture and vegetable pigments age in harmony with the patina of the rose gold, creating a coherent aesthetic identity over time. Shell cordovan represents an exceptional alternative if you prefer leather with a more pronounced patina. For a sporty profile, an armored canvas NATO strap offers practicality without sacrificing the elegance of the case.

The procedure requires specific tools: a dedicated pin remover or a small file. Turn the watch over, locate the pins that secure the strap to the lugs. Insert the remover into the pin slot and rotate to loosen: the pin slides out of the seats. Remove the worn strap. For mounting the new one, align the strap holes with the pins, insert the latter and secure by rotating clockwise until fully locked. If you lack experience, entrust the work to a specialized workshop.

Yes, provided the lug width is 20mm. Any strap with this width is compatible. We recommend manufacturers working with quality leathers (alligator, cordovan, vegetable-tanned calf) and respecting thickness tolerances for precise mounting without excessive play between lug and strap. Milano Straps offers customizable 20mm straps suitable for this case.

Durability depends on the quality of the leather and intensity of use. Vegetable-tanned alligator worn daily retains structural integrity for 8-12 years before requiring replacement. Shell cordovan, if cared for, can last up to 15 years. The critical factor is exposure to moisture and perspiration: if the watch is worn in dry environments, durability increases significantly. An armored canvas NATO strap offers greater longevity (15-20 years), while vulcanized rubber maintains elastic properties for 5-8 years before stiffening.
