Strap for Constellation Quartz 27 Brushed Stainless Steel / Yellow Gold / Champagne Feather

The lug width is 20mm. This specification is fundamental for selecting compatible straps: 20mm represents the distance between the two spring bars of the case. A strap with an incorrect width will not fit properly.

Alligator remains the most refined choice thanks to its natural grain that complements the two-tone case. Shell cordovan offers personality and develops patina over time. For everyday wear, vegetable-tanned calf leather ensures softness. NATO fabric straps are valid for sporting contexts.

Position the watch face down on a soft surface. Use a spring bar tool to compress the spring bar on one side, then remove the old strap. Insert the spring into the hole of the new strap and gently reinsert into the lug. Repeat for the other side. If inexperienced, we recommend having the work done at the atelier.

A quality leather strap, with regular maintenance, lasts on average 3-5 years. Determining factors: frequency of use, exposure to humidity, type of leather (shell cordovan and alligator age more slowly), and care. Monthly cleaning with a slightly acidic damp cloth extends longevity. Casati Milano's 18-month guarantee covers manufacturing defects.
