Frequently asked questions

What is the lug width of the Rolex Datejust 36 reference 116244-0048?

The Rolex Datejust 36 with reference 116244-0048 features a 20-millimetre lug width. This dimension is standard for the 36 mm case and is essential when selecting compatible straps. The measurement is taken between the inner lugs of the case where the strap attaches.

Which strap pairs best with the Datejust 36 116244-0048?

For the white gold and stainless steel two-tone case, we recommend alligator or calf leather with a deployante: alligator emphasises formal luxury and develops character through patina; calf offers softness and daily versatility. A neutral-toned NATO fabric strap (grey, dark blue) is also a contemporary choice. Quality leather preserves the visibility of the two-tone case without competing visually.

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

The strap is secured by spring bars that pass through the case lugs. Using a dedicated tool (thin lever bar), you press the bar to release the internal spring, extracting the old strap. The new strap is inserted the same way, ensuring the bar is fully seated and the strap is properly centred on the lugs. If unsure, consult a certified watchmaker.

Is an aftermarket strap compatible with the 116244-0048?

Yes, provided it is designed for 20 mm lug width. High-quality artisanal straps such as those offered by MilanoStraps are fully compatible and often surpass official Rolex solutions in comfort, versatility, and aesthetic ageing over time. The key is verifying that the lugs are crafted from robust leather and that the maker guarantees precision in finishing.

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

A high-quality leather strap (alligator, shell cordovan, vegetable-tanned calf) typically lasts between 3 and 8 years with daily wear, depending on exposure to moisture, sunlight, and mechanical wear. Vegetable-tanned leather develops a rich patina; industrial tanning maintains colour stability longer. A luxury watch like the Datejust deserves straps of equivalent quality, with replacement every 3–4 years without compromise.
