Strap for Constellation Manhattan 25 Quartz Stainless Steel / Yellow Gold / Silver Diamond / Diamond

The lug width of the Constellation 131.25.25.60.52.002 is 16mm. This measurement represents the distance between the case attachment pins and is fundamental for choosing compatible straps. Only straps specifically dimensioned at 16mm will mount correctly without lateral play or misalignment. We recommend always verifying the measurement with a digital caliper before ordering an aftermarket strap.

For this two-tone stainless steel and yellow gold model, dark brown alligator represents the choice of excellence: the discreet longitudinal grain enhances the case details without visual overload. Vegetable-tanned calf is a valid alternative, as it develops a noble patina over time. For summer contexts, nylon nato fabric offers practicality while maintaining elegance. Quality vulcanized rubber represents the contemporary solution for maximum durability and simplified maintenance.

Strap replacement requires the use of a spring bar remover, a specific tool that allows you to extract the elastic pins that fix the strap to the case lugs. Position the strap on a soft pad, gently insert the remover under the elastic pin until the spring snaps out, then extract the strap. Repeat the procedure on the other side. For installation of the new strap, align the holes with the pins and press gently until they click into position. If you are not experienced, we recommend contacting a professional watchmaker to avoid damage to the delicate attachment mechanisms.

Yes, any strap with a 16mm lug width is technically compatible. However, to maintain the aesthetic integrity and construction quality of your Constellation, we recommend high-end artisanal straps: selected leathers, double-thread stitching, refined finishes. Milano Straps 16mm straps offer complete customization (sizes, initials, thread choice) and guarantee perfect compatibility. The Casati Milano atelier also creates custom pieces with personal consultation and 18-month warranty.

The lifespan of a leather strap depends on frequency of use, climate, and maintenance. A superior quality alligator or calf, with vegetable tanning, has an average life of 3–5 years with daily use, extending to 7–10 years if worn occasionally and stored correctly in a dry environment. Determining factors are humidity (which accelerates deterioration), prolonged sun exposure, and perspiration. Regular maintenance—drying the strap after water contact, avoiding forced bending—significantly extends durability. An artisanal vegetable-tanned leather strap also develops a patina that makes it more robust over time, unlike synthetic leathers which tend to degrade more rapidly.
