The Submariner 16800, seen from the bench

The Rolex Submariner 16800, produced from 1979 to 1988, was the first Submariner to feature a sapphire crystal instead of plexiglass and introduced the screw-down crown with triple-lock system. This 40 mm stainless steel 904L case model is powered by the Rolex caliber 3035 automatic movement with 28,800 vph frequency and approximately 48 hours power reserve. The unidirectional aluminum bezel, luminous Mercedes hands, and solid dial characterize this transitional reference. Water resistance reaches 300 metres with screw-down caseback and crown. The 20 mm lug width is essential for selecting compatible replacement straps.

Frequently asked questions

What is the lug width of the Rolex Submariner 16800?

The Rolex Submariner 16800 has a lug width of 20 mm, measured as the internal distance between the two lugs at the point where they meet the case. This measurement is essential when selecting a compatible replacement strap. Early production examples feature drilled lugs, while later versions have closed lugs.

What is the best strap for the Rolex Submariner 16800?

The ideal choice depends on the intended use and aesthetic preference. For smart-casual or semi-formal wear, a vegetable-tanned alligator strap with a matte finish complements the instrument character of the watch. For sporting or maritime use, a nylon NATO or vulcanised rubber strap is more practical and consistent with the model's origins. Shell cordovan is an excellent option for those seeking a leather that develops a distinctive patina over time.

How do you change the strap on a Rolex Submariner 16800?

To replace the strap on the Submariner 16800, you will need a fine-tipped spring bar tool. Compress the spring bar from the inner side of the lug to release it from its seat, then slide the strap free. Always work on a soft surface to protect the case and bezel from scratches. If in doubt, it is advisable to entrust the task to a qualified watchmaker or specialist atelier.

Are there aftermarket straps compatible with the Rolex Submariner 16800?

Yes. Any aftermarket strap with a 20 mm attachment and standard spring bars is fully compatible with the Rolex Submariner 16800.

How long does a leather strap last on a Rolex Submariner 16800?

The lifespan of a leather strap depends on the material, care routine and frequency of use. A quality vegetable-tanned alligator strap, with moderate daily wear and regular conditioning (a nourishing cream every two to three months, avoiding prolonged exposure to water and perspiration), can last between three and six years while retaining its appearance. Milanostraps backs its straps with an 18-month warranty against manufacturing defects.
