Strap for Constellation Co-Axial Master Chronometer 27 Stainless Steel / Silver Silk

The lug width is 17mm. This dimension defines the internal space between the lugs where the strap is anchored. To verify, measure with a digital caliper the distance between the two lugs, completely excluding the thickness of the lugs themselves. In our catalogues you will find all the straps compatible with this specification.

Honey alligator is the premium choice: the flat-scaled grain perfectly complements the elegance of the case. Shell cordovan offers unparalleled patina and natural ageing over time. Vegetable-tanned leather is a sustainable alternative with vintage character. Ideal thickness: 3.5mm to ensure fluid draping and comfort.

Extract the spring bars using a spring bar tool inserted into the small lateral hole. Gently pull out the old strap. Position the bars of the new strap in the lug housings and press until they lock into place. If you lack experience, a watchmaker ensures precision and avoids damage to the lugs.

Yes, any strap with a 17mm lug width is compatible. Always verify that the spring bars of the aftermarket strap are free from excessive play. Our straps are built with precise tolerances and guarantee optimal fit without slipping.

A high-quality alligator strap with vegetable tanning lasts an average of 4-5 years of daily wear. Durability depends on ambient humidity, frequency of use and maintenance. A leather conditioned monthly with specific creams extends its life to 7-8 years. Shell cordovan, thanks to its fibrous density, reaches even 6-10 years of performance.
