The case features 20mm lugs and maintains the 36mm format characteristic of the collection.

Frequently asked questions

What is the exact lug width of the Rolex Datejust 36 126281RBR-0028?

The Datejust 36 126281RBR-0028 is equipped with 20-millimetre lugs. This measurement is determined by the distance between the inner edges of the lugs affixed to the case and represents the fundamental parameter for the compatibility of any aftermarket strap. Precise measurement using a digital calliper or ruler is essential before purchase.

Which strap material is best suited for the Datejust 36 126281RBR-0028?

For this two-tone Datejust 36 in Everose and steel, alligator leather represents the reference choice: its vertical grain and patina development over time align perfectly with Rolex's aesthetic signature. A natural leather-coloured alligator, dark brown or burgundy complements the two-tone case without visual discord. Italian calf leather with vegetable tanning also offers understated elegance, featuring uniform texture and patina that chronicles daily wear.

How do you change the strap on a Rolex Datejust 36?

Strap replacement on a Datejust 36 requires removal of the lugs through the spring bars that connect them to the case. Use a dedicated spring bar tool to avoid scratching the lugs. Identify the extraction direction (lugs are typically soldered), gently extract the bar and insert the new strap. For Rolex watches, we recommend entrusting this task to a professional watchmaker to prevent case damage.

Is an aftermarket strap compatible with the Rolex Datejust 36 126281RBR-0028?

Yes, provided the strap features exactly 20-millimetre lug width. Straps with this width, crafted from alligator, calf, shell cordovan or technical materials, are fully compatible. It is essential to verify the measurement before purchase: inaccurate measurement results in incompatibility or excessive looseness.

How long does a leather strap last on a Rolex Datejust 36?

Durability depends on material, frequency of wear and maintenance. Premium-quality alligator lasts 5–8 years with daily wear; Italian calf 3–5 years. Shell cordovan, thicker and more resilient, can reach 10 years. Regular maintenance—gentle cleaning and occasional conditioning—significantly extends useful life. The 18-month warranty offered by Casati Milano covers manufacturing defects during the initial usage period.
