Explorer II 1655— lug 19mm

The Rolex Explorer II 1655 features a 19mm lug width. This is a specific and relatively uncommon measurement in contemporary Rolex production. When replacing the strap, it is essential to select a model precisely matched to this width in order to avoid mechanical stress on the original lugs.

The answer depends on intended use and personal taste. Vegetable-tanned calf leather develops an authentic patina over time, consistent with the Tool Watch character of the ref. 1655. Alligator belly leather adds elegance without undermining the visual solidity of the case. Shell cordovan is the preferred choice for intensive daily wear, owing to its dense fibre structure and superior abrasion resistance.

The lugs of the Rolex Explorer II 1655 accommodate standard 19mm spring bars. Using a fork-type spring bar tool, the bar can be compressed and the strap removed without risk of scratching the case. The procedure does not require professional equipment, but does call for a degree of manual dexterity and care to protect the polished surfaces of the watch.

Yes, a wide range of aftermarket straps in 19mm lug width are compatible with the Rolex Explorer II 1655. It is important to verify that the strap's horn profile is correctly shaped to suit the geometry of the Oystercase lug, and that the buckle — standard or deployant — is made from stainless steel to ensure aesthetic coherence and long-term durability.

Longevity depends on leather quality and frequency of use. A quality artisan vegetable-tanned calf strap typically lasts 2–4 years with daily wear. Shell cordovan, thanks to its dense fibre structure, can exceed 5 years. Alligator, when regularly treated with appropriate conditioners, maintains its integrity and appearance for 3–5 years. Prolonged exposure to water and perspiration accelerates deterioration across all leather types.
