Frequently asked questions

What is the lug width of the Rolex Datejust 36 116234-0156?

The lug width (misura ansa) of the Rolex Datejust 36 116234-0156 is 20 millimetres. This measurement represents the internal distance between the two lug attachment points on the case and determines compatibility with all aftermarket straps. To verify the measurement correctly, position a calliper or ruler on the case from the inner edge of one lug to the inner edge of the opposite lug, excluding the bezel.

Which strap is recommended for the Rolex Datejust 36 116234-0156?

For the Rolex Datejust 36 116234-0156 in white gold and stainless steel, the most suitable straps are those in alligator leather with vegetable tanning (dark brown or black), shell cordovan, or vegetable-tanned calf leather. Alligator offers maximum chromatic contrast with the white gold, emphasising the luminosity of the bezel. Vegetable-tanned calf represents the most versatile choice for alternating between formal and informal wear, developing a natural patina over time. Shell cordovan guarantees superior durability and a luminous surface that mirrors the elegance of the case.

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

Changing the strap on a Rolex Datejust 36 requires the use of a dedicated tool (spring bar removal tool) to remove the spring bars connecting the strap to the lugs. Position the flat end of the tool under the spring bar, applying gentle pressure to retract the internal spring and free the end. Repeat the operation on the other lug. Install the new strap by aligning the holes with the lugs and pushing the spring bar until it clicks into place. It is advisable to entrust the operation to a professional watchmaker to avoid scratching the case or damaging the attachment points.

Is an aftermarket strap compatible with the Rolex Datejust 36 116234-0156?

Yes, a quality aftermarket strap with a 20-millimetre lug width is fully compatible with the Rolex Datejust 36 116234-0156. Mechanical compatibility is guaranteed by correct lug width measurement. However, it is essential to choose straps from reliable suppliers that use premium materials (genuine alligator, vegetable-tanned calf, shell cordovan) and artisanal craftsmanship to ensure durability, aesthetics and longevity.

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

The longevity of a leather strap depends on material quality, frequency of wear and maintenance. A quality artisanal strap in vegetable-tanned calf or alligator leather, with moderate wear (3–4 days per week), maintains structural integrity for 12–18 months. Shell cordovan, thanks to natural fibre density, can reach 24–30 months of wear. Constant exposure to humidity, perspiration, thermal fluctuations and UV rays accelerates deterioration. Regular maintenance — cleaning with a microfibre cloth, immediate drying after moisture exposure and seasonal rest — significantly extends the aesthetic life of the strap.
