Explorer II 16570-0001— lug 20mm

The Rolex Explorer II 16570-0001 has a lug width of 20.00mm. This measurement is specific to this model and ensures optimal proportions between the 40mm case diameter and the visual elegance of the strap. Always verify this measurement before ordering a replacement strap to avoid incompatibility with the original spring bars.

There is no universal best choice—only options calibrated to intended use. For formal elegance, alligator with vegetable tanning offers a patina that ages with character. For daily robustness, regenerated calf resists mechanical stress more effectively. For extreme sporting contexts (reflecting the Explorer II's speleological origins), NATO in nylon or cotton ensures practicality and quick changes. Rubber represents the hybrid solution: excellent grip in humidity, easy cleaning, modern aesthetics.

The procedure requires precision. Use a dedicated spring bar tool to compress the attachment springs from underneath. Proceed sequentially on both sides of the case: one lug at a time. The 16570-0001, being a sports model, features well-designed lugs and standard 20mm spring bars, so the process is relatively straightforward. If uncertain, rely on specialised service: Casati Milano offers direct consultation via WhatsApp throughout the entire process.

Yes, provided they are certified for the 20mm lug width. Always verify that the original Rolex spring bars (or equivalent universal 20mm bars) fit correctly into the support cylinders of the new strap. A quality artisanal strap, such as those offered by Milano Straps, is fully compatible and often provides finishing superior to vintage factory straps. The key is avoiding generic products: with a Rolex of this calibre, the aftermarket strap must guarantee construction quality comparable to the original.

Duration depends on tanning method and usage intensity. An alligator strap with vegetable tanning, worn daily in temperate climate, maintains structural integrity for 4–6 years before showing significant cracks. A more robust calf strap resists up to 7–8 years. If worn occasionally or stored away from direct light and extreme humidity, lifespan doubles. Casati Milano provides an 18-month warranty against manufacturing defects: should the strap crack spontaneously due to construction fault, it will be regenerated free of charge. Regular maintenance (cleaning, leather balm every 6 months) significantly extends useful life.
