Strap for Big Crown Diamonds 38 Stainless Steel - Diamond / MOP

The lug width is 19mm. This measurement refers to the distance between the lugs of the case and is the essential technical parameter for selecting a compatible strap. To verify the measurement with precision, position the watch on a flat surface and measure the internal distance between the two upper or lower lugs with a digital calliper. Tolerances of 0.5mm are generally acceptable in standard lugs.

The choice depends on use and aesthetic preference. An alligator leather strap with vegetable tanning maintains balance between elegance and sportiness. A NATO in cotton-polyester 260gsm is ideal for nautical contexts and high perspiration environments. An FKM rubber strap is perfect if you frequently utilise the water resistance of the case. For refined daily wear, burgundy shell cordovan or cognac calf offer evolving patina over time, creating character parallel to the steel case.

Position the watch on a soft cloth with the dial facing down. Identify the passing pins that secure the lugs: in this model they are typically accessible from the rear of the case. Use a spring bar tool to exert gentle pressure on the pins and loosen them on one side, releasing the old strap. Insert the new strap by aligning the holes to the lugs and reinsert the pins. Verify that the strap is securely fixed before wearing the watch.

Yes, any strap with a 19mm lug width is compatible. Artisanal aftermarket straps often offer superior construction quality and materials compared to originals. Ensure the strap is provided with correctly dimensioned spring bars for the attachments of your watch (19mm width). Choose specialised manufacturers who verify compatibility and offer precise tolerances to avoid excessive play or insufficient fixation.

Durability depends on the material, tanning method, and degree of maintenance. A high-quality vegetable-tanned leather strap typically lasts 3-5 years with regular use, with patina that aesthetically improves in the initial years. A shell cordovan strap can last 5-7 years due to the natural density of the leather. Exposure to direct sunlight, prolonged perspiration, and humidity reduce longevity. Periodic treatments with specific balms and drying after humidity exposure significantly extend overall durability.
