Strap for Day-Date 36 Yellow Gold Fluted / President / Silver Diamonds

The lug width is 20 millimetres. This measurement allows you to fit any compatible 20mm strap, whether leather, rubber or fabric. To verify compatibility, insert the spring bar into the lug holes: the internal space must be precisely 20 millimetres.

Alligator is the classic choice for the Day-Date: the natural texture of the pores enhances the perception of luxury and the leather breathes better on the wrist. Shell cordovan with vegetable tanning is an exclusive alternative, with a patina that develops over time. For less formal contexts, black rubber or canvas NATO straps resist summer humidity whilst maintaining the elegance of the gold case.

Position the watch with the lugs facing you. Using a spring bar remover—a thin plastic or steel tool—gently press the internal spring of the spring bar towards the centre of the case to release the end. Remove the strap from the upper half lug, then the lower one. Insert the new strap into the lower half lug, then the upper one, ensuring the spring bars lock completely. Pull the strap lightly to verify the grip.

Yes, provided the lug width is certified at 20 millimetres. High-quality artisanal straps respect Rolex's original tolerances and guarantee the same ease of fitment. We recommend premium materials such as vegetable-tanned alligator or aniline calf leather, which age gracefully whilst maintaining the aesthetic value of the watch over time.

Durability depends on intensity of use and leather quality. A vegetable-tanned alligator strap resists 4–6 years with regular maintenance (cleaning with a damp cloth, quick drying after perspiration). Vegetable-tanned shell cordovan can exceed 7–8 years. Rubber or NATO straps offer greater water resistance and last 5–7 years. Rotating between multiple straps significantly extends the life of each one.
