Strap for Constellation Co-Axial 27 Brushed Stainless Steel / Red Gold Claws / Blue Supernova

The lug width is 16mm. This width is determined by the internal distance between the attachment pins on the case. To verify it, insert a digital caliper into the attachment points: the constant value for this reference is 16mm. Measure with precision as even a 0.5mm error compromises the fit.

Niveum alligator remains the choice of maximum prestige, thanks to its natural texture that harmonizes with the bi-metallic case. For those seeking sustainability, vegetable-tanned calfskin offers aesthetic evolution over time. Shell cordovan guarantees durability exceeding 5 years. Selected in cognac, bordeaux or black tones, they amplify the discreet elegance of the collection.

The change requires a spring bar tool (lever tool). Insert the tip into the small lateral hole next to the pin, gently lift to release the spring, then extract the pin. Repeat on the other side. Install the new strap by reinserting the pins into the case holes. Ensure they click properly. If you prefer to avoid DIY, contact a certified watchmaker.

Yes, all straps with a 16mm lug width are compatible. Artisanal straps from milanostraps.it offer customization in leather, color and stitching thread, guaranteeing quality superior to OEM straps. Always verify that the width is precisely 16mm to avoid play or accelerated wear.

Longevity depends on the material. Standard calfskin resists 2-3 years with daily use. Shell cordovan exceeds 5 years thanks to its dense fibrous structure. Alligator offers resistance similar to shell cordovan. Vegetable-tanned leather evolves aesthetically over time, acquiring a rich patina. Frequency of use, humidity exposure and maintenance significantly influence durability.
