Strap for Automatic Deck Chronograph White Gold Silver

The lug width of the Leroy Marine Range LL202/1 is precisely 20 millimetres. This measurement refers to the internal distance between the two spring bar pins. A manufacturing tolerance of ±0.5 millimetres is acceptable. Before purchasing an aftermarket strap, always verify this measurement on your case using a digital calliper, as even minor variations may affect mechanical compatibility.

For an LL202/1 in white gold, an alligator strap in ebony or a vegetable-tanned calf leather represent the most harmonious choices. Alligator creates subtle contrast through its characteristic grain and cool tonality, reflecting the refined elegance of white gold. If you prefer a patina that evolves with time, opt for vegetable-tanned calf in dark brown or cognac shades. For summer sporting use, a NATO strap in navy or dark grey offers functionality without aesthetic compromise. In aquatic environments, high-density rubber is the only sensible option.

The procedure requires minimal complexity but careful execution. Use a professional spring bar tool: insert the thin blade into the gap between the pin and the case, applying controlled outward pressure to compress the internal spring mechanism. Once the first pin is released, repeat on the second side. Remove the worn strap. For installation of the new strap, align the holes with the case and fully insert the first pin, then compress the second pin and seat it on the case. Verify that both pins are firmly secured before wearing the watch. Never force: if resistance is encountered, verify alignment carefully.

Yes, provided it is explicitly certified for 20-millimetre lug width. High-quality artisanal straps from specialised manufacturers (such as those in alligator or vegetable-tanned calf) are fully compatible with the LL202/1. Always verify that the producer clearly communicates the lug width specification. For NATO or rubber straps, compatibility is universal, as these attachment types do not employ case-specific pins.

Durability depends on tanning method and usage patterns. A calf strap with vegetable tanning, subjected to moderate daily wear, maintains structural integrity for 3–5 years before replacement becomes necessary. Alligator, owing to its denser fibre structure, can extend this duration to 6–8 years. Constant exposure to humidity, perspiration and ultraviolet radiation accelerates leather degradation. To extend strap lifespan, apply protective cream containing natural waxes every 6–8 months and store in a dry environment when unworn. Vegetable-tanned straps naturally develop patina which, whilst altering the original appearance, does not compromise mechanical functionality.
