Submariner 116613ln-0001— lug 20mm

The Rolex Submariner 116613LN-0001 has a lug width of 20 millimetres. This width is standard for 40mm Submariner models and is measured between the two pins that pass through the integrated case lugs. Any strap compatible with 40mm Rolex watches will accommodate this specific dimension.

Strap selection depends on usage and aesthetic context. For formal wear, we recommend cognac brown alligator or vegetable-tanned black calf leather. For sports or marine use, NATO canvas, FKM rubber, or Cordura fabric offer water resistance and practicality. Ideal colour pairing considers contrast between the yellow gold and steel case: warm and neutral tones enhance elegance without competing with the instrument's bicolour appearance.

To change the strap, unscrew the crown (rotate the protective gasket). On the inner side of the lugs, you will find two horizontal pins: use a spring bar remover tool to gently compress the pin and extract the old strap. Insert the new strap by sliding the pins into the lugs until you hear the locking click. This operation requires care: if in doubt, contact an authorised service centre.

Yes. Aftermarket straps with a 20mm lug width are fully compatible with the 116613LN-0001. Always verify the width and construction quality: European-origin leathers (Mississippi alligator, French calf, American shell cordovan) guarantee durability and aesthetic coherence with the watch's prestige. Casati Milano straps, handcrafted in Italy with artisanal finishes, maintain the visual proportion between case and wrist.

Longevity depends on material and usage. Quality alligator or calf, with regular maintenance (damp cloth cleaning, conditioning every 6–8 months), lasts 3–5 years of daily wear. NATO or fabric resists 2–3 years. FKM rubber lasts 4–6 years. The Twinlock crown on the 116613LN-0001 reduces moisture penetration into the case, indirectly protecting the strap. Store the watch in a dry environment when not worn.
