Strap for Constellation Manhattan 25 Quartz Stainless Steel / Sedna Gold / MOP

The lug width is 16 mm. This measurement represents the distance between the two pins on which the strap wraps and is essential to ensure compatibility with aftermarket straps. Always verify this dimension with a digital caliper before ordering a new strap, positioning the probe between the spring bars.

For this model with Sedna Gold case and mother-of-pearl dial, we recommend alligator in dark tones (black or chocolate brown) for maximum elegance, or vegetable-tanned calf leather that develops a rich patina over time. Shell cordovan is ideal for durability and sophisticated texture. For summer, an anthracite grey FKM strap or navy blue Tropic maintains formality with practicality.

The strap is changed by removing the spring bars (the lateral pins that hold it in place). Use a spring bar tool or dedicated tool to gently push the lateral pin, extracting the pin. Once both pins are free, the old strap detaches. Insert the new strap by aligning the holes at the ends of the lug and reinsert the pins until they click into place. If you are unsure, the Casati Milano service can perform the operation with warranty.

Yes, any strap made for 16 mm lug width is compatible with your Constellation. On milanostraps.it you will find a selection of 16mm straps ready for shipment, customizable in leather, color and details. Always verify that the supplier specifies the correct lug width to avoid excessive tension during wear.

Durability depends on the material and use. A quality alligator or shell cordovan, worn daily, maintains structural integrity for 3-5 years before requiring replacement. Vegetable-tanned calf can last 2-4 years depending on frequency of use and exposure to sun and humidity. Casati Milano provides an 18-month warranty on all handcrafted straps, and the after-sales service includes consultation on maintenance and leather aging.
