Datejust 36 116285bbr-0011— lug 20mm

The Rolex Datejust 36, including reference 116285bbr-0011, features a lug width of 20 millimetres. This measurement is taken internally between the spring bar pins that hold the strap. It is essential to distinguish this from the Datejust 41, which requires 21mm, and lady models, which use 18mm.

For the Datejust 36 in rose gold, we recommend alligator in cognac or tabac brown tones, dark shell cordovan, or vegetable-tanned calf leather in honey-brown. These artisanal materials naturally complement the warmth of rose gold and develop elegant patina over time, enhancing the visual continuity between metal and leather.

Strap replacement involves removing the spring bar pins at either end of the case. Using a dedicated spring bar tool, gently depress the spring mechanism to release the pin. Slide the pin out carefully, then insert it through the new strap and release the spring gradually until it clicks into place. For inexperienced users, professional jeweller assistance is recommended.

Yes, provided it meets the precise 20mm lug width specification. Artisanal custom straps such as those from Milanostraps are fully compatible and represent an elegant alternative to original Rolex bracelets, offering greater aesthetic personalisation and seasonal versatility.

The durability of an artisanal leather strap depends on usage intensity, climate exposure, and maintenance. On average, a quality alligator or shell cordovan strap maintains full functionality for 3 to 6 years of daily wear. The leather develops progressive patina, creating a unique character. Casati Milano straps include an 18-month warranty covering manufacturing defects and premature structural wear.
