Datejust 36 116201-0085— lug 20mm

The lug width of the Rolex Datejust 36 116201-0085 is 20 mm. This measurement corresponds to the distance between the spring bars of the case. You can verify it by measuring the internal space between the two horizontal attachment points with a digital calliper. Lug width is essential for selecting a compatible strap with precision.

For the Datejust 36 116201-0085, in Everose and stainless steel, we recommend vegetable-tanned alligator, shell cordovan, fine-grained calf leather, or vulcanised rubber. Dark brown alligator amplifies formal elegance; burgundy calf dialogues with Everose; black with vegetable tanning is the universal choice. Black rubber matches the steel component, emphasising the bicolour balance.

To change the strap on a Rolex Datejust 36, obtain a spring bar tool. Position the tool in the lug to be removed, press inward to release the spring bar pin, then extract it. Repeat on the other lug. Insert the pins of the new strap into the case attachments and ensure they click into position. If you are not experienced, consult a specialised watchmaker.

The durability of a leather strap depends on the material and usage. Vegetable-tanned alligator lasts 3–5 years with ordinary care; shell cordovan, due to its density, reaches 5–7 years. Superior calf leather lasts 2–4 years. Determining factors: sun exposure, humidity, frequency of use, wrist perspiration. Periodic maintenance (hydration with colourless balm) significantly extends strap life.
