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

The lug width of the Rolex Day-Date 36 128349RBR-0032 is 20mm. This measurement represents the distance between the lugs (the pins that attach the strap to the case) and is the only parameter that determines strap compatibility. A 20mm strap will fit perfectly without any play or excessive tightness.

For the 128349RBR-0032, we recommend alligator leather with vegetable tanning (featuring natural, irregular grain) or shell cordovan, which develops a transparent patina over time. Both materials enhance the white gold through chromatic contrast and texture. For versatility, vegetable-tanned calf leather or rubber in neutral tones are functional alternatives without aesthetic compromise.

Changing the strap requires a specialised tool to extract the 20mm pins that connect the strap to the case. If you lack experience, we recommend visiting an authorised Rolex service centre or a qualified watchmaker. With Casati Milano, we can guide you through the process via WhatsApp and provide your custom strap with an 18-month warranty.

Yes, any strap with a 20mm lug width is mechanically compatible with the Day-Date 36 128349RBR-0032. Compatibility is determined solely by lug width, regardless of the strap manufacturer. However, we recommend choosing materials and finishes—such as vegetable-tanned leather and alligator—that enhance the watch.

The longevity of a leather strap depends on daily wear, climate conditions, and maintenance. A quality artisanal alligator or shell cordovan strap with vegetable tanning typically lasts 3-5 years with consistent use, developing desirable patina during the first year. The Casati Milano 18-month warranty covers manufacturing defects; regular maintenance (cleaning, drying) significantly extends durability.
