Strap for Master Collection Date 25.5 Stainless Steel - Pink Gold / Silver / Bracelet

The lug width is 13 millimetres. This specific measurement is critical for ensuring compatibility with third-party strap solutions. Use a digital calliper positioned perpendicularly across the lugs to measure accurately. A 12mm strap will fit too tightly; a 14mm strap will create excessive lateral play and compromise the visual integration between case and strap.

We recommend an alligator leather strap with vegetable tanning. The fine, regular grain of alligator leather harmonises with the delicate case proportions, and the natural patina that develops over time enhances the perception of conscious luxury. Valid alternatives include calf leather straps with fine-grain texture in shades that complement the case materials: tobacco brown, gunmetal grey, or deep black. NATO straps offer practical-elegant versatility for daily rotation.

You will require a spring bar tool to compress the internal spring mechanism. Position the flat end in the upper slot of the lug, apply gentle downward pressure to compress the spring, and slide the old strap laterally to extract the spring bar. Repeat on the opposite side. Align the new strap holes with the spring bars and reposition them carefully. Handle the two-tone steel and rose gold case with deliberate caution to avoid unintended scratches during the operation.

Yes, absolutely. Any aftermarket strap with a 13mm lug width is fully compatible with the Master Collection L2.128.5.79.7 without case modifications. Online retailers offer extensive selections in varied materials: alligator, calf, rubber, and fabric. We recommend verifying construction quality and user reviews before purchase, prioritising specialised manufacturers. The Casati Milano atelier also provides bespoke strap commissions with exclusive personalisation options.

Leather strap longevity depends on usage intensity, maintenance, and climate exposure. A quality alligator strap, subjected to periodic care (gentle cleaning, occasional conditioning), retains functionality and aesthetic appeal for 5–7 years of daily wear. Calf leather, being more delicate, typically lasts 3–5 years. The natural patina that develops constitutes added aesthetic value. Casati Milano provides an 18-month warranty on all bespoke straps, covering manufacturing defects.
