Strap for Datejust 36 Stainless Steel Fluted / Jubilee / Black Computer

The lug width of the Rolex Datejust 36 116234-0079 is 20 millimetres. This measurement is specific to the 36mm model and is calculated as the internal distance between the two metal lugs where the strap is installed. A compatible 20mm strap should fit smoothly without forcing, ensuring stability during daily wear without unwanted movement.

For the 116234-0079 with its two-tone white gold and steel case, we recommend a cognac or honey alligator strap, which creates chromatic harmony with the gold top-case. Alternatively, a smooth black calf leather strap is the universal choice for formal contexts, whilst a burgundy shell cordovan offers character and natural patina development over time. Your choice depends on your wardrobe and primary usage context.

To change the strap, use a specialised tool (spring bar remover or lug tool) to remove the lug pins. Position the watch face-down on a soft cushion, insert the remover into the small lateral hole of the lug and gently push the pin free. Repeat on the opposite end. Once both pins are removed, the bracelet separates from the case. Install the new 20mm strap by following the reverse procedure, ensuring both pins are securely seated. If inexperienced, have a professional service technician perform this operation to avoid damage.

Yes, any strap with a 20mm lug width is compatible with the 116234-0079, provided the internal width conforms to tolerance specifications (19.5–20.5 mm). High-quality artisan straps, such as those offered by Casati Milano, provide superior aesthetic and craftsmanship flexibility compared to original Rolex bracelets. Always verify compatibility with your supplier before purchase.

A high-quality leather strap (alligator, calf, or shell cordovan) on a watch worn daily has an average lifespan of 3–5 years, depending on exposure to moisture, perspiration and climatic conditions. Vegetable-tanned leather may last longer whilst developing patina over time. A rubber strap offers greater longevity (5–8 years) as it resists moisture more effectively. Casati Milano provides an 18-month guarantee against manufacturing defects, covering the initial wear-in period.
