Strap for Constellation Manhattan 29 Co-Axial Master Chronometer Yellow Gold / Diamond / MOP

For a Constellation 131.58.29.20.55.001 in 18K yellow gold, alligator remains the choice of aesthetic and functional excellence. The natural texture of the reptile and luminous reflections harmonise beautifully with the golden patina. Alternatively, a vegetable-tanned calf in intense cognac colour or a natural beige taupe alligator maintains correct chromatic proportion. Avoid cool tones or sports materials (NATO, rubber) that betray the distinctly jewellery-like identity of this model.

Strap replacement requires a spring removal tool: position the watch with the lugs facing upward, insert the thin end of the tool into the small lateral slot of the spring bar, gently press outward to disengage it, and the strap or bracelet will detach. Reverse the operation to install the new strap. If you prefer certified security, the Casati Milano atelier performs the service with preventive inspection of the spring bar and lug functionality.

An artisanal quality leather strap (alligator, calf, cordovan) maintains structural and aesthetic integrity for 3 to 5 years, provided regular use and conservative care (drying after humidity exposure, avoiding prolonged immersions, occasional conditioning with neutral creams). Alligator tends toward superior longevity thanks to the natural density of the leather. Vegetable tanning ages with visible patina, transforming into a narrative element of the watch. At Casati Milano, regeneration and scheduled replacement services are available.
