Strap for Big Crown Complication Stainless Steel / Silver

The lug width of this model is 20mm. This measurement represents the distance between the two terminal points where the strap attaches to the case. It is essential to verify that the compatible strap is exactly 20mm, as even minor variations (such as 19.5mm or 20.5mm) would prevent a fit without play.

For this aviator model, we recommend three options: vegetable-tanned alligator leather for artisanal elegance, nappa calf in warm tones (brown, cognac) to preserve the field watch character, or canvas NATO to emphasise the military heritage. For intensive use or water sports, structured rubber Tropic is a modern and durable solution.

Strap replacement requires a dedicated tool called a spring bar remover. Position the watch with the dial facing downward, locate the small cylindrical pin fixing the lug to the case, and gently push with the remover to extract it. Repeat on the opposite side. Insert the new strap by aligning the lugs with the holes and reposition the pin. Alternatively, our appointed ateliers perform the change with instrumental precision.

Longevity depends on frequency of use, climate conditions, and leather quality. A vegetable-tanned calf strap worn daily maintains structural integrity for 3–5 years. Exposure to humidity, perspiration, and intense sunlight accelerates ageing. A high-quality alligator strap offers superior durability (5–8 years). The patina and micro-markings that leather develops over time increase its narrative value.
