Strap for Submariner Date Rolesor / Blue / Cerachrom

The lug width of the Rolex Submariner 116613lb-0005 is 20 millimetres. This measurement represents the external distance between the two horizontal pins protruding from the case and defines the space into which the strap must fit. It can be verified by measuring directly with a digital calliper positioned between the case lugs. This standardisation ensures compatibility with a wide range of high-quality aftermarket straps.

The most suitable strap depends on the intended use and aesthetic preferences. For formal contexts, brown or mahogany alligator creates an elegant dialogue with the yellow gold on the case. For robust daily use, vegetable-tanned calf leather offers durability and a patina that improves over time. Shell cordovan represents the ideal compromise: naturally waterproof and develops a deep patina. For sporting versatility, a nautical nylon NATO strap or FKM rubber ensures waterproofing and minimal maintenance requirements.

Changing the strap requires extraction of the two horizontal pins that pass through the case lugs. Using a specific tool (spring bar tool) or a small screwdriver, apply light lateral pressure on the pins to release them from their seats. Once extracted, the old strap is removed and the new one is inserted by feeding one end first, then progressively inserting the pins into both lugs. This operation should be performed with extreme care to avoid scratching the case. If uncertain, consult a professional watchmaker.

Yes, provided the strap is specifically designed for a 20-millimetre lug width. This standardisation ensures the strap engages correctly in the case lugs without lateral play and maintains the visual proportion of the 116613lb-0005. It is important to verify that the strap manufacturer explicitly declares compatibility with this lug width. Custom artisan straps can be manufactured on commission to adapt perfectly to the case specifications.

Durability depends on the material, use and maintenance. A high-quality alligator or calf leather typically lasts 5–7 years with moderate daily use, developing a pleasant patina. Shell cordovan, being more resistant, can last 7–10 years. Frequent exposure to water, perspiration and UV rays accelerates leather ageing. Regular maintenance—gentle cleaning, complete drying after humidity exposure, periodic conditioning with neutral wax—significantly extends strap life. Artisan straps backed by manufacturing guarantees offer protection against production defects for 18 months.
