Strap for Constellation Quartz 35 Stainless Steel / Red Gold / Silver

The lug width is 20 millimeters. This is the distance between the case terminals where the strap attaches. It is essential to verify this measurement before ordering an aftermarket strap to avoid incompatibility.

Alligator represents the noblest choice thanks to its regular texture that enhances the two-tone design. For daily use, vegetable-tanned calf leather offers durability and a patina that evolves over time. Shell cordovan is ideal for those seeking characteristic rigidity and deep tones.

The strap is replaced by removing the spring bars that connect the bracelet to the case using a dedicated tool (spring bar tool). With the bracelet removed, the integrated Manhattan lug remains clearly visible. Installing the new strap is the reverse operation: insert the spring bars into the lug slots until they are fully locked.

All straps with a 20 millimeter lug width are compatible. You can find a wide selection online ready for shipment and customizable in material, color, initials, and stitching thread. For a complete bespoke experience, the Casati Milano atelier creates custom straps with personal choice of leathers.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with moderate use, longer if well maintained. The natural aging of leather increases its charm rather than being a defect. Casati Milano straps benefit from an 18-month warranty and can be replaced if worn beyond normal use.
