Strap for Rolex Submariner 5513

The Rolex Submariner 5513 has a lug width of 20mm, measured internally between the two case lugs. This dimension remained consistent throughout the model's entire production run, from 1962 to 1989. When replacing the strap, it is advisable to verify the measurement with a calliper before purchasing.

The choice depends on intended use and aesthetic preference. For formal settings, an alligator strap in vegetable-tanned leather with a steel buckle or deployant clasp is the most refined option. For daily or casual wear, smooth calf leather or shell cordovan offer comfort and develop a natural patina over time. A NATO nylon strap is historically coherent with the tool watch identity of the model.

The strap on the Rolex Submariner 5513 is removed using a spring bar tool to release the spring bars connecting the strap to the case lugs. Care should be taken to avoid scratching the case: protecting the lugs with masking tape before proceeding is recommended. Alternatively, a watchmaker or authorised retailer can carry out the replacement without risk.

Yes, the aftermarket offers straps compatible with the Rolex Submariner 5513 in all 20mm lug widths. Milanostraps.it offers handcrafted straps in leather, alligator, calf and shell cordovan made specifically for this width, with curved or straight ends adaptable to the Rolex lug profile. The quality of materials and craftsmanship is crucial to ensure longevity and a proper fit.

The lifespan of a leather strap depends on the material, frequency of use, and exposure to moisture and perspiration. A high-quality alligator strap with vegetable tanning, worn daily, typically lasts 2–4 years before requiring replacement. Shell cordovan, being denser and more compact, tends to last longer. For a Submariner intended for water use, a rubber or NATO strap is recommended.
