Strap for Defy Extreme Double Tourbillon Forged Carbon - Rose Gold

The lug width of this model is 23 millimetres. This measurement is taken between the inner shoulders of the lugs, excluding gaskets or sealing materials. A 23mm lug width is specific to the 45mm Defy Extreme and ensures correct visual proportion with the case diameter whilst distributing the chronograph's weight evenly across the wrist.

The optimal choice depends on intended use and aesthetic preference. Natural alligator with geometric grain creates maximum contrast against the angular case and rose gold. Shell cordovan in chestnut brown offers deep patina and metronomic gravitas. Vegetable-tanned calf leather presents contemporary sophistication. Technical rubber ensures maximum daily versatility. All materials require precisely 23mm lug width for seamless compatibility.

Use a quality spring bar tool to avoid scratches on the rose gold case. Position the watch securely, insert the flat end of the tool into the gap between lug and case to compress the inner spring, remove the old strap, and insert the new one ensuring perfect alignment with the 23mm lug width. For premium timepieces, this operation is best performed by a specialist watchmaker.

All straps with precisely 23mm lug width are compatible. Milano Straps offers a dedicated catalogue for this measurement in alligator, shell cordovan, vegetable-tanned calf, rubber and NATO options. Always verify exact lug width at the inner shoulder before purchasing. Bespoke straps from Casati Milano can be personalised in length, initials and rose gold deployant clasp finishing.

Durability depends on tanning method, frequency of use and atmospheric exposure. Vegetable-tanned alligator resists 3-4 years under moderate wear. Shell cordovan, owing to its compact fibre structure, can exceed 5-6 years. Calf leather is more vulnerable to environmental agents and benefits from rotation with alternative straps. A rose gold deployant clasp remains serviceable and can be transferred to a new strap. Casati Milano provides 18-month warranty on all bespoke work.
