Strap for Big Crown Diamonds 38 Stainless Steel / MOP

The lug width of this model is exactly 19 millimetres. This is an intermediate measurement that falls outside the most common standards (18mm and 20mm), so finding a compatible strap requires precision. You can verify the measurement by placing a digital calliper between the two spring bars of the original strap.

The best strap depends on your intended use. For formal settings, vegetable-tanned leather in cognac or dark brown creates harmony with the satin steel case. For robust daily wear, a NATO in cotton or Cordura canvas maintains the tool-watch character. For pure sportiness, an FKM rubber strap offers comfort and practicality. Alligator represents the luxury compromise, with natural grain and superior durability.

Strap replacement is straightforward and requires no special skills. Locate the two lateral spring bars that pass through the case lugs. Using a spring bar tool (or a sufficiently thin pen), gently push the bar from one side to extract it. Once one lug is free, the old strap slides off easily. Insert the new strap by aligning the holes with the spring bars, and reinsert the bars until they click into position.

Absolutely yes, provided it respects the 19-millimetre lug width. Artisanal aftermarket straps often offer construction quality superior to the original strap, with exclusive material choices and customised finishes. MilanoStraps offers a dedicated range in 19mm leather, NATO and rubber, all tested for guaranteed compatibility with this model.

The durability of a leather strap depends on the quality of the leather and the frequency of wear. A vegetable-tanned leather of artisanal quality retains structure and flexibility for 3-5 years of moderate daily use, then begins to show visible wear at the lugs. Alligator and shell cordovan last longer, up to 7-10 years. Keeping the strap in a cool, dry location and avoiding prolonged humidity significantly extends the product's lifespan.
