Strap for Big Crown Complication Stainless Steel - Rose Gold / Black

The lug width of this model is 20mm. This measurement corresponds to the external distance between the case lugs and represents the specific dimension for strap insertion. Accurate measurement of this specification is essential before purchasing an aftermarket strap to ensure a perfect and secure fit.

For this Big Crown, we recommend materials that respect the aeronautical and functional character of the model. Alligator with vegetable tanning offers sartorial elegance and develops natural patina over time. Italian shell cordovan guarantees superior structural integrity and deep coloration. Anilline calf provides immediate tactile softness. For sporty use, dense-weave NATO or vulcanised natural rubber maintains tool watch versatility without compromise. A deployant clasp in stainless steel or titanium completes the solution.

Strap replacement requires sartorial precision to avoid case scratching. Use a dedicated spring bar tool, positioning it perpendicularly to the pin and gently pushing outward to release the internal spring. Once the pin is removed from the first lug, slide off the old strap. Insert the new strap, realign the hole, and reinsert the pin, ensuring the spring seats correctly. We recommend working on a soft surface to minimise the risk of indentation marks.

Yes, provided the strap is specifically designed for 20mm lug width and features a standard spring bar pin (3.0-3.2mm diameter). All 20mm straps available on Milano Straps have been verified for Big Crown compatibility. The strap material (alligator, calf, NATO, rubber) does not affect mechanical compatibility, only aesthetic presentation and wear characteristics.

Leather strap longevity depends on material and usage patterns. Alligator with vegetable tanning and Italian shell cordovan, if properly maintained and rotated seasonally, retain structural functionality for 4-6 years. Anilline calf typically lasts 2-3 years before requiring replacement. Vulcanised natural rubber offers maximum longevity, 5-7 years, with minimal maintenance required. Direct sunlight exposure, extreme humidity, and perspiration accelerate ageing. Rotating between different straps significantly extends the useful life of each.
