Strap for Rolex Submariner 6538

The Rolex Submariner 6538 has a lug width of 19 mm, a measurement specific to the early Submariner generations produced between 1955 and 1959. Later references adopted a 20 mm lug width, so it is essential to verify the exact reference before purchasing a compatible strap.

For the Submariner 6538, the most coherent choices are a vegetable-tanned calf strap — which develops a natural patina over time — and a nylon NATO strap for sporting use. An Hornback alligator strap suits formal occasions, while vulcanised rubber is the optimal choice for humid environments or water exposure.

To replace the strap on the Submariner 6538, you will need a fine-tipped spring bar tool. Insert the tip into the inner slot between the lug and spring bar end, compress the bar and slide the strap free. Care must be taken to avoid scratching the steel lugs, which on vintage examples are often unpolished and should remain so to preserve originality and value.

Yes. Aftermarket straps with a 19 mm attachment and standard 1.5 mm diameter spring bars are fully compatible with the Rolex Submariner 6538. Milanostraps.it offers a curated selection of handcrafted straps made specifically for this reference, available in various materials and finishes, with bespoke length options based on wrist circumference.

The lifespan of a leather strap depends on the material, finish and frequency of use. A quality calf strap with vegetable tanning and burnished edges typically lasts 18 to 36 months with regular wear. High-grade cordovan and alligator can last 3 to 5 years with proper care, provided they are kept away from prolonged moisture and direct sunlight. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
