Oyster Perpetual 1002— lug 20mm

The Rolex Oyster Perpetual 1002 has a lug width of 20mm. This measurement is standard across the entire 34mm Oyster family produced between 1959 and 1987, and is one of the most widely available sizes in the aftermarket strap sector.

For formal use, a vegetable-tanned alligator strap at 20mm complements the clean aesthetic of the 1002 with understated elegance. For daily wear, smooth or grained calfskin is the most practical choice. In sporting or marine contexts, a nylon NATO or vulcanised rubber strap provides the necessary durability without compromising fit or comfort.

To replace the strap on a Rolex Oyster Perpetual 1002, use a spring bar tool to release the spring bars from the lugs. Work on a soft surface to protect the case from scratches. If uncertain, a qualified watchmaker can complete the operation in minutes with no risk to the watch.

Yes. The Rolex Oyster Perpetual 1002 accepts any aftermarket strap with a 20mm lug width and standard spring bars. Milano Straps offers a curated selection of handcrafted straps in calfskin, shell cordovan, alligator, and NATO nylon, all compatible and available in 20/16mm or 20/18mm configurations depending on the chosen buckle.

Longevity depends on the material and frequency of use. A standard calfskin strap typically lasts 1 to 2 years with daily wear. A shell cordovan or vegetable-tanned alligator strap, owing to the density of the leather, can last 3 to 5 years or more when properly maintained with leather conditioner and kept away from prolonged moisture. Casati Milano backs its straps with an 18-month warranty against manufacturing defects.
