Datejust 36 116200-0055— lug 20mm

The lug width (strap width) of the Rolex Datejust 36 116200-0055 is precisely 20mm. This is the measurement between the two lugs on the watch case and is essential for selecting a compatible strap. Always verify this measurement using a digital calliper, measuring between the lugs rather than across the case.

We recommend alligator leather or vegetable-tanned calf leather for the 116200-0055. Alligator delivers formal elegance and works superbly with suits. Vegetable-tanned calf is more versatile for business and smart-casual contexts. Both materials develop a natural patina over time, adding visible character to your Datejust.

Remove the three pins (one on each side, one on the crown) using a spring bar tool. Position the case horizontally and gently press the pin outward with a steady, controlled movement. Insert the new 20mm strap, position the pins, and press until they click into place. If unfamiliar with this procedure, have an authorised watchmaker perform the replacement to avoid case scratching.

Yes, provided the strap width is exactly 20mm. However, not all aftermarket straps match Rolex manufacturing standards. Verify that the bars are stainless steel and the strap exhibits no lateral play when fitted. Artisan-made Italian straps such as those from Casati Milano offer perfect compatibility with the original attachment system.

A high-quality leather strap (alligator or vegetable-tanned calf) worn daily typically lasts 3–5 years before replacement becomes necessary. Longevity depends on: frequency of wear, exposure to water and humidity, and maintenance practices (regular cleaning and conditioning). If stored in controlled conditions and worn occasionally, a premium strap can last 7–10 years.
