Frequently asked questions

What is the lug width of the Rolex Datejust 36 116234-0116?

The Rolex Datejust 36 116234-0116 features a 20 mm lug width. This measurement refers to the distance between the two spring bar holes that secure the strap to the case. To verify correctly, place a ruler between the lugs in the perpendicular direction: the result should be exactly 20 mm.

Which strap do you recommend for the Datejust 36 116234-0116?

For a white gold and stainless steel case of this proportion, we recommend alligator with medium grain in dark brown or black, calf leather in vegetable tanning, or shell cordovan which develops a natural patina over time. Each material interacts differently with the reflectivity of white gold, creating specific luminous effects.

How do you change the strap on a Rolex Datejust 36 116234-0116?

Strap replacement requires extraction of the two spring bars from the lugs using a dedicated spring bar tool with a flat end. Position the tool perpendicular to the spring bar, push towards the centre of the case to release the internal spring, extract the bar and repeat from the opposite side. Then insert the bars into the new strap following the reverse procedure.

Can I use an aftermarket compatible strap with the 116234-0116?

Yes, any strap with a 20 mm lug width is physically compatible. However, for a case of this calibre we recommend a strap of elevated quality: the choice of leather, the thickness of the material, the buckle finish (standard, deployante, or hook buckle) significantly influence the wear experience and longevity of the pairing.

How long does a natural leather strap last on a watch worn daily?

A high-quality leather strap (alligator, shell cordovan, dyed calf) worn daily on a watch like the Datejust has an average lifespan of 3-5 years, depending on climate, humidity, and frequency of exposure to perspiration. Materials such as shell cordovan and vegetable tanning tend to age with elegance, developing a patina that communicates conscious wear rather than degradation.
