Strap for Constellation Co-Axial 38 Stainless Steel / Silver

The lug width for the model 123.10.38.21.02.001 is 20 millimetres. This is the distance between the two attachment pins located at the ends of the case. Always verify with a calliper or contact our team before purchasing a strap to ensure exact compatibility.

For this reference we recommend black or dark brown alligator for an elegant formal look, vegetable-tanned calfskin for everyday versatility with colour development over time, or shell cordovan for those seeking maximum refinement. The choice depends on your personal style and usage context.

The strap is attached to the case's attachment pins via the lug. You will use a special tool called a "spring bar tool" to compress the internal spring of the pin and slide it into the seat. If you are not experienced, we recommend visiting a qualified watchmaker or contacting the Casati Milano atelier directly for replacement service.

A premium leather strap, especially if vegetable-tanned or shell cordovan, typically lasts between 4 and 7 years of daily use, depending on care and exposure to moisture and UV rays. Calfskin is more resistant to repeated flexing; shell cordovan is less prone to visible wear but requires periodic maintenance. Milano Straps offers repair services and replacement of worn parts with an 18-month warranty.
