The Submariner 6536, seen from the bench

The Rolex Submariner 6536 is a significant reference from the first generation of Submariner watches produced in the mid-1950s, commercialized between 1955 and 1959. It features a 37 mm stainless steel case, a Rolex Caliber 1030 automatic movement with approximately 38 hours of power reserve, and water resistance certified to 100 meters. The 19 mm lug width is a distinctive identifier of this model, narrower than later Submariner generations.

Frequently asked questions

What is the lug width of the Rolex Submariner 6536?

The Rolex Submariner 6536 has a lug width of 19 mm. This measurement is specific to the early Submariner models produced between 1955 and 1959 and is narrower than the 20 mm adopted in subsequent generations. It is essential to verify this dimension with a digital calliper before purchasing an aftermarket strap.

What is the best strap for the Rolex Submariner 6536?

The most suitable straps for the Submariner 6536 are crafted in vegetable-tanned alligator, matte calf leather, or shell cordovan, all at 19 mm width. Alligator with a botte grain enhances the understated black dial, while calf leather develops a personal patina over time. For a more sport-oriented approach, a vulcanised rubber strap is the most functional option.

How do you change the strap on a Rolex Submariner 6536?

To replace the strap on the Submariner 6536, a 1.8 mm springbar tool is required. The original springbars are slender, compatible with the narrow 19 mm lugs. It is advisable to work on a soft surface to protect the stainless steel case and to ensure the replacement springbars are the correct length before fitting.

Are there aftermarket straps compatible with the Rolex Submariner 6536?

Yes, there are high-quality aftermarket straps compatible with the Rolex Submariner 6536, provided they feature a 19 mm lug width. Milanostraps.it offers a curated selection of leather, rubber, and fabric straps made specifically for this size, with full customisation available through the Casati Milano atelier.

How long does a leather strap last on a Rolex Submariner 6536?

The lifespan of a leather strap depends on the material and conditions of use. A quality vegetable-tanned alligator strap, worn regularly but not in sporting conditions, can last between three and five years while retaining its aesthetics and structural integrity. Shell cordovan, owing to its dense fibrous structure, tends to last even longer. Prolonged exposure to water and perspiration should be avoided to preserve the leather.
