Frequently asked questions

What is the lug width of the Rolex Day-Date 36 128348RBR-0064?

The lug width of the Rolex Day-Date 36 128348RBR-0064 is 20 mm. Rolex maintains this measurement consistently across the entire Day-Date 36 family, making it compatible with a wide range of quality aftermarket straps.

What is the best strap for the Rolex Day-Date 36 128348RBR-0064?

For a yellow gold case with a diamond-set bezel, an alligator strap in vegetable-tanned leather offers the most coherent aesthetic and material pairing. A deployant clasp in gold-toned metal preserves the chromatic continuity with the case. Cordovan and smooth calf leather in warm tones — cognac, tobacco, bordeaux — are equally considered choices.

How do you change the strap on a Rolex Day-Date 36 128348RBR-0064?

The bracelet and straps on the Day-Date 36 are released using a spring bar tool inserted into the lateral hole of the lugs. It is advisable to work on a soft surface to protect the yellow gold case from scratches. For a first-time change on an unmodified example, assistance from a qualified watchmaker is recommended.

Are there aftermarket straps compatible with the Rolex Day-Date 36 128348RBR-0064?

Yes. Any strap with a 20 mm lug width and straight end is compatible with the Rolex Day-Date 36 128348RBR-0064. milanostraps.it offers a selection of artisan straps in leather, cordovan and technical materials produced specifically for this lug width, with buckles available in various metal finishes.

How long does a leather strap last on a Rolex Day-Date 36 128348RBR-0064?

Longevity depends primarily on material quality and daily care. A vegetable-tanned alligator strap, kept away from excessive moisture and perspiration and periodically treated with conditioning cream, can last between 3 and 6 years whilst retaining structural and aesthetic integrity. Cordovan tends to last longer due to the density of its fibres. milanostraps.it offers an 18-month guarantee against manufacturing defects.
