Strap for Constellation Co-Axial 38 Co-Axial Day-Date Stainless Steel / Red Gold / Silver

The lug width of the Constellation 123.20.38.22.02.001 is 20 millimetres. This measurement is essential for identifying compatible straps. You can verify it by measuring with a digital caliper between the inner edges of the lugs, positioning your wrist frontally. All 20mm straps from the Milano Straps collection fit this model perfectly.

For the Constellation 123.20.38.22.02.001, vegetable-tanned alligator represents the most coherent choice with formal elegance. A dark brown or burgundy alligator naturally complements the rose gold case. Alternatively, shell cordovan in wine tones offers a brilliance that amplifies the sophistication. Anthracite grey calf is ideal if you prefer dynamism without sacrificing the austerity of the design.

To change the strap on your Constellation, remove the watch from your wrist and lay it flat. Locate the lugs (side fastening pins) at 12 and 6 o'clock. Using a dedicated tool (strap change pen or similar implement), gently push the pin downward to extract the strap from the first lug. Repeat on the other side. Insert the new strap by aligning the pins with the lugs and push until it clicks. Ensure the strap is firmly seated before wearing the watch.

Yes, absolutely. Any strap with a 20mm lug width is compatible with the Constellation 123.20.38.22.02.001. Milano Straps offers an extensive collection of artisanal straps in various materials – alligator, calf, shell cordovan, rubber – specifically designed for this size. The important thing is to choose straps with high construction quality standards, in line with the watch's benchmark.

A quality leather strap, with ordinary care, has a useful life of 4-6 years. Vegetable-tanned alligator and shell cordovan age elegantly, developing a patina that increases their aesthetic value over time. Durability depends on: frequency of use, exposure to water and humidity, regular maintenance (cleaning with a soft cloth). Milano Straps straps benefit from an 18-month warranty and can be restored by Casati Milano through restitching and specific treatments.
