Strap for Rolex Submariner 5508

The lug width of the Rolex Submariner 5508 is 20mm. It is measured using a digital calliper placed internally between the two lugs, flush against the case. The lugs feature a pronounced inward curve typical of vintage Submariners, so it is advisable to verify that the strap's end pieces match this curvature before fitting.

The most suitable materials for the Rolex Submariner 5508 are hand-stitched vegetable-tanned calf leather, alligator, and shell cordovan, all cut to 20mm with curved ends. For a more sporting or period-correct aesthetic consistent with the watch's production years (1958–1962), a nylon NATO strap or vulcanised rubber strap are equally coherent choices.

To replace the strap on a Rolex Submariner 5508, you will need replacement spring bars and a spring bar tool or a fine-tipped lever. The lugs accept standard 20mm spring bars. It is strongly recommended to have the operation carried out by a watchmaker experienced in vintage timepieces to avoid scratching the stainless steel case or damaging the lug holes.

Yes, a wide range of aftermarket straps are compatible with the Rolex Submariner 5508, provided they feature a 20mm lug width and curved ends to accommodate the original lug geometry. Milanostraps.it offers a curated selection of handcrafted straps in various materials available in this size, produced by Casati Milano with steel buckles and deployant clasps.

The lifespan of a leather strap on a Rolex Submariner 5508 depends primarily on the material and frequency of use. A well-maintained vegetable-tanned calf strap typically lasts 2–4 years with daily wear. Shell cordovan, owing to its dense fibre structure, can exceed 5 years. High-quality alligator offers comparable durability. Regular exposure to salt water or perspiration accelerates deterioration; for aquatic or intensive sporting use, a vulcanised rubber strap is the recommended alternative.
