Datejust 16013— lug 20mm

The Rolex Datejust 16013 has a lug width of 20mm, measured internally between the two lugs of the case. This is the standard measurement for all 36mm Datejust references of this generation, ensuring broad compatibility with aftermarket straps.

For the Datejust 16013 in Rolesor configuration (stainless steel and 18k yellow gold), a vegetable-tanned alligator strap in warm tones — cognac, honey or tobacco brown — offers the most coherent aesthetic pairing. Polished box-calf leather is a formal and versatile alternative. For more active use, a flat-profile vulcanised rubber strap is the most practical technical choice.

The strap on the Datejust 16013 is removed using a springbar tool, inserting the fine tip into the lug hole or side channel to compress the spring bar ends. Care must be taken not to scratch the gold surfaces. Alternatively, a watchmaker or specialist retailer can complete the swap in a matter of minutes.

Yes. The standard 20mm lug width ensures full compatibility with quality aftermarket straps. It is important to verify that the strap ends have a curved profile (curved ends) to fit correctly against the Datejust case. Milanostraps.it offers handcrafted straps in this size, made from selected materials and available in various buckle and deployant configurations.

The lifespan of a leather strap depends on the material, frequency of use, and exposure to perspiration and moisture. A quality vegetable-tanned alligator strap, with moderate daily use, typically lasts 2–4 years. Shell cordovan, due to its dense fibrous structure, tends to last longer while developing a distinctive patina. Avoiding prolonged contact with water and sweat significantly extends the strap's service life.
