Strap for Constellation Manhattan 25 Quartz Stainless Steel / Silver Silk

The lug width of the Constellation 131.10.25.60.52.001 is 16 millimetres. This measurement is specific to the 25mm ladies' models and represents the internal distance between the two lateral lugs of the case. Any aftermarket strap must respect this dimension for correct fitting and harmonious aesthetics.

For the 131.10.25.60.52.001 we recommend natural alligator, which pairs perfectly with the architecture of the case lugs, or vegetable-tanned calf leather for a patina that evolves over time. Shell cordovan represents an alternative for those seeking robustness and chromatic depth. The choice depends on use: formal for alligator, versatile for calf, sporty for vulcanised rubber.

Changing the strap requires the use of a specific tool to remove the spring bars. Position the watch in a soft vice, use a thin lever tool to compress the spring bar and slide it out of the lug. Once the old strap is removed, insert the new one by aligning the holes and slide the spring bar until it clicks into position. If you are not confident, entrust the task to a professional.

All straps with a lug width of 16 millimetres are compatible with your Constellation. Always verify the measurement before purchase. On milanostraps.it you will find a selection of 16mm straps available online, customisable in sizes, initials and choice of stitching thread, or you can rely on the Casati Milano atelier for a completely bespoke strap.

The lifespan of a leather strap depends on the quality of the material, use and care. A well-made alligator or shell cordovan strap can last 5–7 years with regular use and proper maintenance. Vegetable-tanned calf leather tends to last slightly less, 3–5 years. Regular cleaning with a soft cloth and avoiding prolonged water exposure significantly extend the life of the strap.
