Frequently asked questions

What is the exact lug width of the Rolex Datejust 36 116238-0068?

The lug width of the Rolex Datejust 36 116238-0068 is 20 millimetres. This dimension is specific to the 36mm case and represents the distance between the two lugs where the strap is attached. To verify correctly, measure with a digital calliper perpendicular to the case, from the inner wall to the inner wall of the lugs.

Which strap is recommended for the Rolex Datejust 36 116238-0068?

For the Datejust 36 in solid yellow gold, alligator Grade A in dark brown or cognac represents the most sophisticated choice, enhancing the colour contrast with the gold. Alternatively, vegetable-tanned calf leather in reddish-brown creates an authentic vintage effect. Shell cordovan is the most durable choice for those seeking extraordinary longevity. Each material should be selected from specialised ateliers such as Casati Milano to ensure certified artisanal quality.

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

Changing the strap on a Datejust 36 requires specific tools: a spring bar tool (small forked probe) to extract and insert the spring bars—the steel bars that secure the strap to the case lugs. Position the tool perpendicularly, gently push upwards or downwards to release the bar, remove the old strap and insert the new one, aligning it perfectly. If you are unsure, entrust the task to a professional watchmaker to avoid scratching the case.

Is an aftermarket strap compatible with the Rolex Datejust 36 116238-0068?

Yes, any strap with a 20mm lug width is compatible with the Datejust 36. However, to preserve the aesthetic integrity and value of the watch, it is recommended to choose straps of excellent quality. Artisanal straps crafted on commission at ateliers such as Casati Milano guarantee construction standards equal to the original Rolex strap, with the possibility of personalising length, thickness and finish.

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

Durability depends on the material and usage. An alligator Grade A strap, with proper maintenance (annual conditioning with specific creams, protection from extreme humidity and heat), lasts 5-8 years before requiring replacement. Shell cordovan can last 10+ years thanks to its natural rigidity. Vegetable-tanned calf leather, being softer, requires reconditioning every 2-3 years. Casati Milano offers an 18-month warranty on manufacturing defects and post-sale support for maintenance needs.
