Strap for Datejust 36 Stainless Steel Diamond / Jubilee/ Bronze Floral

The Rolex Datejust 36 reference 116244-0003 features a lug width of 20 millimetres. This is the distance between the attachment pins located at the extremities of the case. The lug depth is approximately 5.5 millimetres, so the strap must have a total thickness not exceeding 6 millimetres to ensure smooth passage through the pins without play or binding.

The choice depends on usage and personal aesthetic. For classic elegance, alligator with vegetable tanning is the historical choice, developing a noble patina over time. Full-grain calf offers a homogeneous, smooth surface ideal for those seeking luminosity. Shell cordovan, derived from the equine posterior, develops unique intrinsic lustre. For daily practicality, natural rubber or technical fabric straps are compatible and contemporary. Consult the Casati Milano atelier for personalised guidance.

To change the strap, you will need: a spring bar tool, a soft surface to prevent case scratching, and manual precision. Position the watch on a soft cloth. Insert the thin end of the spring bar tool into the small recess of the pin, pushing towards the case centre to compress the internal spring. Extract the pin gently. Repeat on the other side. Reverse the procedure to insert the new strap. If you prefer to avoid risk, Casati Milano offers a strap-changing service at the Milan atelier by appointment.

Yes, provided the lug width is precisely 20 millimetres and the total strap thickness does not exceed 6 millimetres. Quality artisanal straps are generally compatible with this specification. Ateliers such as Casati Milano create custom straps by measuring the attachment rings of your specific Datejust 36, ensuring optimal fit without play and without risk of case damage. The guarantee covers manufacturing defects for 18 months.

Durability depends on material and usage. Full-grain calf of artisanal quality resists 3-5 years with daily wear, developing progressive patina. Alligator with vegetable tanning, more resistant, can last 5-8 years. Shell cordovan, particularly robust, easily exceeds 8 years. Natural rubber straps last 4-6 years. Ageing is natural: sun, humidity, perspiration and movement determine gradual softening. To prolong life, alternate the strap with other pieces. Casati Milano provides repair and restoration services for worn leather.
