Explorer II 1018— lug 19mm

The Rolex Explorer II 1018 features a lug width of 19mm, measured between the inner walls of the Oyster case lugs. This specification is particular to this reference and should not be confused with the more common 20mm adopted on later Explorer II models. For an accurate measurement, a digital calliper positioned perpendicularly to the strap axis is recommended.

The ideal strap for the Rolex Explorer II 1018 depends on intended use and context. For an elegant and durable pairing, vegetable-tanned calfskin or a hornback alligator strap are the most coherent choices given the watch's technical character and white dial. For sport or outdoor use, a vulcanised rubber strap in 19mm offers waterproofing and resilience. A deployant clasp is recommended to extend the life of a leather strap.

To replace the strap on a Rolex Explorer II 1018, the spring bars must be removed from the Oyster case lugs using a dedicated spring bar tool or a fine-tipped lever. Work on a soft surface to avoid scratching the case. The original spring bars measure 19mm and must be matched by compatible bars supplied with the new strap. If in doubt, a qualified watchmaker can perform the operation in a matter of minutes.

Yes, high-quality aftermarket straps compatible with the Rolex Explorer II 1018 are available, provided they feature a 19mm lug width. Milanostraps.it offers a selection of handcrafted straps in leather, alligator, shell cordovan and rubber, made to fit this reference with reinforced stitching and spring bars included. It is essential to verify that the manufacturer explicitly states compatibility with 19mm lugs.

The longevity of a leather strap depends on material quality, care and frequency of use. A high-quality vegetable-tanned calfskin strap, kept dry and periodically treated with leather conditioner, can last between 2 and 4 years with daily wear. An alligator or shell cordovan strap, owing to the greater density of the hide, may exceed 5 years. Using a deployant clasp significantly reduces stress on the stitching and buckle hole, extending the life of the strap.
