Strap for Constellation Manhattan 25 Quartz Stainless Steel / Grey Diamond

The lug width of model 131.10.25.60.56.001 is 16mm. This dimension is fixed and determines compatibility with any aftermarket strap. It is measured by positioning a caliper perpendicular to the two insertion holes of the spring bars (lugs).

It depends on your primary use. For formal occasions, black or deep burgundy alligator intensifies the understated elegance of the case. For daily wear, vegetable-tanned calf develops a patina that ennobles with time. If you seek modernity, a desaturated grey or blue NATO communicates discretion. For maximum durability, quality rubber is a deliberate choice.

Position the watch with the lugs facing upward. Using a spring bar tool (or even a small screwdriver), gently press the elastic pin from one side, lifting the old strap. Repeat on the other side. Insert the new 16mm strap by threading the pin into the space between the lugs and allowing elastic tension to secure it. Verify that it is firmly seated.

Yes, absolutely. As long as the lug width is 16mm, the strap is compatible regardless of the brand. Milanostraps offers handcrafted straps online ready in 16mm, or customizable through the Casati Milano atelier with leather, dimensions, and details of your choice.

Durability depends on the tanning method and use. A vegetable-tanned calf strap lasts 3-5 years with moderate daily wear, evolving into a desirable patina. An alligator or shell cordovan resists 4-6 years while maintaining rigidity. A handcrafted strap with an 18-month warranty covers manufacturing defects; the natural wear of leather is a physiological and noble process.
