Strap for Rolex Explorer II 216570

The lug width of the Rolex Explorer II 216570 is 21 millimetres. This measurement represents the distance between the two lugs (the case extensions) where the strap is affixed. Measuring this dimension accurately with a digital calliper is essential to ensure compatibility with aftermarket straps and prevent damage to the case during installation.

For the 216570, black alligator straps are recommended for a minimalist and formal aesthetic, or shell cordovan for a warmer effect with patina that evolves over time. Vegetable-tanned leather represents a sustainable alternative that conveys functional austerity. Choice depends on intended use: technical straps in NATO or rubber maintain the model's exploratory character.

Strap replacement requires the removal of the lug pins using a dedicated tool. Insert a small pin into the hole of the pin from inside the case, apply gentle pressure and slide the pin outward. Repeat for both sides. It is advisable to work on a soft surface (felt or cloth) to avoid scratching the case. If inexperienced, it is preferable to contact an authorised service centre.

Yes, any strap with a 21mm lug width is compatible with the 216570, provided the pins are of the same width and length as original Rolex pins. Artisanal straps made by specialised manufacturers such as Casati Milano offer guaranteed compatibility with standard dimensions. Always verify pin dimensions (generally 1.8mm diameter for Rolex) before purchase.

The lifespan of a leather strap depends on the type of leather and conditions of use. A quality alligator or shell cordovan strap has an average life of 3-5 years with moderate use; vegetable-tanned leather tends to last slightly longer due to its more structured fibre. Prolonged exposure to moisture, perspiration and temperature fluctuations reduces longevity. Proper maintenance (drying and seasonal conditioning) significantly extends strap life.
