Frequently asked questions

What is the lug width of the Rolex Datejust 36 116244-0017?

The lug width of the Rolex Datejust 36 116244-0017 is 20 millimetres. This dimension is specific to the 36-millimetre case model and is measured shoulder-to-shoulder between the case lugs. It is essential to verify this measurement before purchasing an aftermarket strap, as it is not interchangeable with other Datejust models of different diameters.

What is the best strap material for the Datejust 36 two-tone model?

For the Datejust 36 116244-0017 in white gold and stainless steel two-tone, we recommend fine-grain alligator for understated elegance, vegetable-tanned calf for conscious ageing, or shell cordovan for natural rigidity and deep lustre. The choice depends on use case: formal occasions favour alligator, daily wear suits calf, uncompromising luxury suits cordovan.

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

Strap replacement requires a proper spring bar tool to compress the micro-pins and release them from the case lugs. If you lack experience, consulting a professional watchmaker is advisable to prevent accidental scratches on the case. The pins must be reinserted straight and parallel, without any twisting.

Can I use a quality aftermarket strap on a Rolex 116244-0017?

Yes, absolutely. A quality artisanal strap often enhances the wearing experience of the Datejust 36, offering superior colour versatility and material quality compared to standard Rolex straps. The key is ensuring that the lug width is exactly 20 millimetres and that the construction is solid, with well-centred lugs and secure fastening.

How long does a leather strap last on a Rolex worn daily?

A quality leather strap, with vegetable tanning or genuine alligator, supports 3–5 years of daily wear before requiring replacement. Durability depends on exposure to moisture, perspiration and direct sunlight. Proper maintenance (rapid drying, occasional vegetable balm application) extends useful life. Rubber or synthetic straps last 1–2 years.
