Strap for Constellation Co-Axial 35 Stainless Steel / Red Gold / Diamond / Silver

The lug width of the Constellation 123.25.35.20.52.001 is 16 millimetres. This dimension represents the distance between the two spring bars that anchor the strap to the case and corresponds to the proportional relationship between the case diameter (35mm) and the bracelet attachment architecture. Always measure the internal distance between the lugs using a digital calliper to ensure maximum precision.

For the Constellation 123.25.35.20.52.001, we recommend three primary options: 1) Alligator with vegetable tanning for maximum elegance and natural patina development over time; 2) Fine-grained calf leather with semi-gloss finish, offering a balance between refinement and practicality; 3) High-quality rubber for more sporty and versatile usage. Your choice depends on frequency of wear and desired aesthetic intention. The Constellation in Red Gold and stainless steel pairs particularly well with dark brown or black alligator.

The Constellation 123.25.35.20.52.001 features an integrated Manhattan bracelet, so strap change requires spring bar removal with a proper tool. Position the watch on a soft pad and use a spring bar tool to gently lift the bars upward from the bottom. Proceed alternately between upper and lower lugs to avoid case distortion. Verify that the spring bars are correctly inserted into the new strap before wearing the watch. When in doubt, contact the Casati Milano atelier for safe professional removal.

The longevity of a leather strap depends on frequency of wear, moisture exposure and material quality. An artisanal strap in vegetable-tanned alligator or shell cordovan typically lasts 4–7 years with daily wear. Calf leather typically lasts 2–4 years. Superior quality straps develop a patina that increases their character over time. Protection from direct water exposure and aggressive detergents significantly extends strap life. The Casati Milano atelier guarantees 18 months on all bespoke-made straps.
