Frequently asked questions

What is the lug width of the Rolex Datejust 36 116244-0029?

The Rolex Datejust 36 reference 116244-0029 has a lug width of 20 mm, measured internally between the two case lugs. It is advisable to verify the measurement with a digital calliper before ordering an aftermarket strap.

What is the best strap for the Rolex Datejust 36 116244-0029?

For a case combining 18ct white gold and 904L stainless steel such as the 116244-0029, the most suitable materials are polished alligator in neutral tones (grey, midnight blue, black) for formal settings, shell cordovan for a more personal character, or vegetable-tanned calf leather for everyday use. A deployant clasp in steel or white gold completes the pairing with constructive consistency.

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

To replace the strap on a Datejust 36, a dedicated 1.8 mm springbar tool is required. Insert the tool into the slot on the lug, compress the spring bar, and slide the strap out laterally. Care must be taken to avoid scratching the case; alternatively, Casati Milano offers a fitting service at the atelier.

Are there aftermarket straps compatible with the Rolex Datejust 36 116244-0029?

Yes. Any strap with a 20 mm lug width and standard spring bars is technically compatible with the Rolex Datejust 36 116244-0029. Milano Straps offers a selection of handcrafted straps in various materials, all made with reinforced ends and finishes suited to precious metal cases.

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

Longevity depends on the material and usage. A quality alligator strap with vegetable tanning, rotated with other straps and kept away from water, will retain its characteristics for 3 to 5 years. Shell cordovan, owing to its compact fibre structure, can last considerably longer while developing a distinctive patina. Milano Straps provides an 18-month guarantee against manufacturing defects.
