The Datejust represents one of Rolex's historic models, introduced in 1945 as the first self-winding watch with date indication. It features the automatic caliber 3235 with hour, minute, second and date functions, certified as a chronometer. The 36mm case has 20mm lugs.

Frequently asked questions

What is the lug width of the Rolex Datejust 36 126284RBR-0015?

The lug width is 20 millimetres. This measurement is critical when purchasing compatible aftermarket straps. It is measured from the inside of the lug, from the base to the apex where the case accommodates the strap.

What is the best strap for the Rolex Datejust 36 126284RBR-0015?

For this two-tone model (white gold and stainless steel), we recommend dark brown alligator, vegetable-tanned calf in natural tones, or shell cordovan in burgundy. The choice depends on intended use: formal elegance for premium leather, restrained sportiness for waxed NATO. Milanostraps stocks dedicated 20mm collections.

How do I change the strap on my Rolex Datejust 36?

The procedure requires specialised tools: a lug removal tool and a work bench. Position the watch on a stable support, carefully unscrew the lugs and extract the old strap. Position the new strap and secure the lugs with firm, consistent pressure. The Casati Milano service is recommended to ensure precise execution.

Are aftermarket straps compatible with the Rolex Datejust 36 126284RBR-0015?

Yes, provided the lug width is precisely 20mm. Milanostraps straps are tested and certified for this dimension. Always verify the lug width prior to purchase to avoid incompatibility issues.

How long does a leather strap last?

A premium leather strap (alligator, vegetable-tanned calf, shell cordovan) has an estimated lifespan of 5-7 years with daily wear, if subjected to regular maintenance. Patina develops beautifully over time. A poorly maintained strap may wear sooner; a well-cared strap can exceed 10 years. Vegetable tanning ages more nobly than chromium tanning.
