Strap for Constellation Co-Axial 38 Stainless Steel / Grey

The lug width of this model is 20mm. This is the distance between the lugs of the 38mm case. It is important to verify this measurement with a digital caliper before purchasing an aftermarket strap, positioning yourself perpendicularly between the two lugs of the case.

The ideal strap depends on your style: for formal wear, we recommend dark brown or black alligator in vegetable tanning, which enhances the sober geometry of the case. For everyday versatility, calf leather with natural aging in neutral tones (gray, taupe) offers elegance and practicality. A Cordura® NATO represents the most functional sporty alternative.

The strap is attached to the case via standard lugs with spring bars. To change it, use a dedicated strap changing tool: insert the flat fork under the spring bar, gently lift to release the pin, and extract the old strap. Insert the new strap by aligning it to the lugs and press until the spring locks into place. If you are not experienced, the operation takes a maximum of 2-3 minutes with the correct tool.

Yes, 20mm aftermarket straps are widely compatible. Milano Straps offers a collection of customizable artisanal leather straps with monogram finishes and choice of stitching thread.

A quality leather strap, worn daily, has an average lifespan of 3-5 years before showing visible signs of wear (cracks, edge fraying). Longevity depends on: tanning type (vegetable ages better than chrome), frequency of wear, climate, and moisture exposure. Premium leathers such as shell cordovan resist up to 7 years. Milano Straps includes 18-month warranty on all straps produced by the Casati atelier.
