Frequently asked questions
What is the lug width of the Rolex Submariner 5510?
The Rolex Submariner 5510 features a 20mm lug width, measured internally between the two case horns at both 12 and 6 o'clock. This dimension is standard across the Submariner line of the late 1950s and ensures full compatibility with the vast majority of 20mm aftermarket straps available today.
What is the best strap for the Rolex Submariner 5510?
For a vintage piece such as the 5510, a smooth vegetable-tanned calfskin strap is the most period-correct choice, developing a genuine patina with wear. Alternatively, a matte-finish alligator or shell cordovan strap offers refined texture and character. A nylon NATO strap honours the watch's tool origins whilst providing everyday practicality.
How do I change the strap on a Rolex Submariner 5510?
To replace the strap on the Submariner 5510, use a quality spring bar tool — preferably a forked-tip type — to release the spring bars from the case lug holes. Work on a padded surface to protect the case and bezel from scratches. Given the rarity and value of this reference, entrusting the operation to a qualified watchmaker or strap specialist is strongly advisable.
Are there aftermarket straps compatible with the Rolex Submariner 5510?
Yes, any strap with a 20mm lug width is compatible with the Rolex Submariner 5510. The aftermarket offers options in handcrafted leather (calfskin, alligator, shell cordovan), nylon NATO, vulcanised rubber and steel mesh. Milano Straps provides a curated selection of handmade 20mm straps, with bespoke options available through Casati Milano.
How long does a leather strap last on a Rolex Submariner 5510?
The longevity of a leather strap depends on the quality of the hide, the tanning method and daily maintenance. A high-grade vegetable-tanned strap, kept away from prolonged water exposure and excessive humidity, can last between two and five years with regular use. Shell cordovan and top-tier alligator straps tend to last longer due to the density of their fibre structure. Milano Straps backs its straps with an 18-month warranty against manufacturing defects.
