Strap for Datejust 36 Rolesor Everose Fluted / Jubilee / Black Computer

The Rolex Datejust 36 116231-0101 has a lug width of 20mm. This measurement corresponds to the spacing between the lugs of the case and is the standard for all 36mm Datejust models produced over the past four decades. Any strap marked as 20mm will fit perfectly onto the spring bars of the 116231-0101.

For the Datejust 36 116231-0101 in rose gold and stainless steel, alligator leather with vegetable tanning in medium brown represents the traditional choice: its regular grain amplifies the rose gold's lustre without competing with it. Alternatively, shell cordovan in bourbon colour develops a patina over time that harmonises the two metals, whilst black calf leather with a steel deployante clasp offers maximum formality.

To change the strap on a Rolex Datejust 36, you must extract the spring bars (the small metal pins securing the strap to the case lugs) using a dedicated tool (spring bar tool). Gently press one spring bar laterally, remove the old strap, insert the new one by aligning the holes, and reposition the spring bar. If uncertain, Casati Milano offers a strap-change service at the Milan atelier.

Yes, any strap with a 20mm lug width is mechanically compatible with the 116231-0101. Many quality manufacturers, including Casati Milano, produce artisanal 20mm straps specifically tested for the Datejust. The key is to verify the 20mm width compliance and construction quality to preserve your Rolex's value and aesthetics.

A quality leather strap (alligator, calf, or shell cordovan) on a daily-wear timepiece lasts between 4 and 8 years, depending on the material and seasonality. Vegetable-tanned alligator tends to develop a patina that can deteriorate with humidity and heat; shell cordovan is more resistant to atmospheric agents. Casati Milano offers an 18-month warranty on manufacturing defects, and most straps can be restored at the atelier.
