Frequently asked questions

What is the correct lug width for the Rolex Datejust 36 116244-0051?

The lug width (distance between the internal lugs) of the Rolex Datejust 36 116244-0051 is 20mm. This measurement is taken internally, and any strap intended for this model must feature a 20mm terminal section to fit correctly into the case lugs without play or forcing.

Which strap materials are best suited for the Datejust 36 in white gold and stainless steel?

Alligator remains the reference choice for the 116244-0051: its regular grain perfectly complements the refinement of the white gold case. Vegetable-tanned calf leather offers a patina that develops over time, imparting character to the piece. NATO or FKM rubber represent sportive alternatives, though they deliberately contrast with the formal elegance of the case.

How do you change the strap on a Rolex Datejust 36 116244-0051?

To change the strap, use a spring bar tool (specialized spring bar removal tool). Position the watch on a soft surface, insert the flat tip into the small lateral hole of the lug, lift the internal spring gently, and extract the suspension pin. Repeat on the opposite side. Install the new strap by reversing the procedure, ensuring the pins are fully seated in the lugs.

Is an aftermarket strap compatible with the Datejust 36 116244-0051?

Yes, any strap with a 20mm lug width is compatible with the 116244-0051, regardless of brand. High-quality artisanal straps often represent superior construction compared to Rolex OEM straps, offering more diverse colour options and materials. Always verify lug width before purchase, and allow for custom leather strap production timelines.

What is the lifespan of a leather strap on a Rolex Datejust 36?

A well-maintained alligator or calf leather strap lasts approximately 4–7 years before requiring replacement. Longevity depends on frequency of use, exposure to humidity and temperature fluctuations, and application of specific hydrating creams. A vegetable-tanned leather strap tends to wear more quickly in the keeper (the section threading through the buckle), though it develops superior aesthetic patina over time.
