Strap for Oyster Perpetual 36 Stainless Steel / Beige

The lug width of the Rolex Oyster Perpetual 36 reference 126000-0012 is 20 mm. This measurement is taken between the two lugs of the Oystersteel 904L case and determines compatibility with any aftermarket strap. It is one of the most common lug widths across Rolex's 36mm range.

The ideal choice depends on intended use and dial colour. For formal occasions, a vegetable-tanned alligator strap with curved ends in 20mm enhances the elegance of the Oyster case. For daily or sports use, box-calf leather or vulcanised rubber straps offer durability and comfort. A NATO nylon strap is the most versatile and lightweight option for summer or casual wear.

To replace the strap, use a springbar tool to remove the spring bars connecting the strap to the case lugs. Work on a soft surface to protect the polished case. The lugs of the 126000-0012 have a curved profile: always ensure the chosen strap features curved ends compatible with the Oyster case geometry.

Yes. The aftermarket offers a wide range of compatible straps in 20mm with curved ends suited to the Oyster case. MilanoStraps offers handcrafted straps in alligator, calf leather, shell cordovan and rubber, available bespoke or online, all in 20mm lug width and fully compatible with reference 126000-0012.

The lifespan of a leather strap depends on hide quality, tanning method and daily use. A high-quality vegetable-tanned alligator strap, regularly treated with a neutral conditioner, will maintain structural integrity and develop a fine patina for 3 to 6 years under normal wear. Box-calf leather offers comparable longevity. Prolonged exposure to water and perspiration should be avoided to preserve the leather's structure.
