Strap for Day-Date 36 White Gold Diamond / White - Roman / President

The lug width of the Rolex Day-Date 36 128349rbr-0025 is exactly 20.00 mm. This measurement is specific to this reference and was engineered to maintain the visual and structural balance of the 36 mm case. To verify the lug width, measure the distance between the two lugs inside the case where the strap pins are positioned. A custom-made strap ensures perfect fit and desired aesthetics.

For a white gold Day-Date 36, genuine alligator remains the most aristocratic choice, in cream white or honey beige tones that enhance the cool tonality of white gold. Alternatively, vegetable-tanned calf leather offers versatility and a developing patina that creates pleasing contrast with white gold. For those seeking modern elegance, navy blue calf or shell cordovan represent sophisticated options. Your choice depends on intended usage and personal aesthetic preference.

Changing the strap on the Day-Date 36 requires specific tools: a pin remover or spring bar tool to extract the pins securing the strap to the case lugs. Position your watch securely on a holder, locate the pins at both ends of the strap, and apply controlled pressure to remove them. Remove the old strap and position the new one with correct alignment to the lugs. Reinsert the pins carefully. If you are not experienced, we recommend having a professional watchmaker or Casati Milano's service perform this operation.

Yes, you can use quality aftermarket straps on the 128349rbr-0025, provided the lug width exactly matches 20 mm. Many standard market straps are produced for 22 mm lugs, making the fit inadequate. Choosing a custom-made artisanal strap guarantees perfect compatibility, material selection (alligator, calf, shell cordovan), and construction quality that honours your watch's value.

The lifespan of a leather strap depends on material, usage, and maintenance. A quality artisanal alligator strap can last 5-7 years with daily wear and regular maintenance (cleaning, hydration). Vegetable-tanned calf leather typically lasts 4-6 years, developing a prized patina. Shell cordovan, due to its structural density, can exceed 8 years. Preventive maintenance—avoiding prolonged moisture exposure, gentle regular cleaning, periodic hydration—significantly extends strap lifespan. Casati Milano offers an 18-month warranty on manufacturing defects.
