Frequently asked questions

What is the lug width of the Rolex Datejust 36 ref. 116243-0027?

The lug width is exactly 20 millimetres. This measurement refers to the internal space between the two lugs of the case. To verify it, remove the strap and measure from lug to lug: you should read 20 mm. This specification is crucial when purchasing an aftermarket strap compatible with your Datejust 36.

Which strap is best suited for the Rolex Datejust 36 116243-0027?

For the mother-of-pearl dial and gold/steel combination, we recommend a natural alligator strap dyed cognac, dark brown, or aged burgundy. Alligator pairs perfectly with the model's sophistication and ages beautifully, developing a unique patina. English-grain calf leather is a valid alternative for those preferring greater daily versatility. Discover our compatible 20mm straps online.

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

Use a spring bar removal tool, available for just a few euros. Place the watch on a soft surface, position the tool at the small hole at the base of the lug, and press gently to release the pin. Once the pin is extracted, the old strap separates from the case. Insert the new strap by aligning the holes, reinsert the pin with even pressure until it clicks into place. The operation should be completed in less than two minutes.

Can I use an aftermarket strap on my Rolex Datejust 36?

Absolutely yes. An aftermarket strap of the correct lug width (20 mm) fits perfectly onto the Datejust 36 116243-0027 without any mechanical alterations. The artisanal quality of a strap made from premium leather (alligator, calf, vegetable-tanned) often exceeds that of the original Rolex strap, offering aesthetic customisation and comparable or superior durability. Consult a specialised craftsman to ensure construction precision.

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

A high-quality natural leather strap (alligator or calf) lasts 5-7 years with daily wear, if properly maintained. Durability depends on the environment (humidity, sun exposure, frequency of use), tanning method (vegetable tanning lasts longer than synthetic fast dyes), and your lifestyle. A vegetable-tanned strap subject to periodic maintenance (gentle cleaning, conditioning with natural fat) can exceed 10 years. Natural leather fears constant humidity and prolonged direct sunlight: store it in a dry place when not worn.
