Strap for Rolex Submariner 116618ln

The Rolex Submariner 116618ln is equipped with a lug width of 20mm. This measurement refers to the distance between the internal ends of the spring bars that support the strap. It is essential to verify this measurement before purchasing an aftermarket strap to ensure compatibility with the 40mm case diameter.

For a yellow gold 18k 116618ln, we recommend straps in black alligator leather with medium grain texture, or cordovan in burgundy tones that develop a deep patina over time. Both enhance the warmth of the gold without competing visually. An alternative is vegetable-tanned calf leather in dark brown, which gains character and depth as it ages.

To change the strap, you need to remove the spring bars at the lug ends using a watch spring bar tool. Position the tool in the small lateral hole of the spring bar and gently press to release it. After extracting the spring bars, the original strap separates from the case. Insert the new strap and reinsert the spring bars, ensuring they click fully into position with audible confirmation.

Yes, any strap with a 20mm lug width is compatible with the 116618ln. Ensure the strap is of artisanal quality and that the terminal ends (the lugs) are precisely cut to fit the case perfectly. On milanostraps.it, you can consult the complete collection of compatible 20mm straps.

A natural leather strap of artisanal quality lasts between 3 to 6 years under normal daily use conditions. Frequent exposure to water and humidity—common with a Submariner—accelerates ageing. Casati Milano guarantees all straps for 18 months against manufacturing defects, but with regular maintenance (neutral cleaners, thorough drying), the lifespan extends significantly longer.
