Frequently asked questions
What is the lug width of the Rolex Day-Date 36 128348RBR-0070?
The lug width of the Rolex Day-Date 36 128348RBR-0070 is precisely 20mm. This dimension is standardised on the case and admits no variation: the strap must fit between the lugs with zero lateral play. Measure the lug width using a digital calliper, positioning the points between the inner edges of the lugs.
Which strap is most suitable for the Day-Date 36 in yellow gold?
For the yellow gold Day-Date 36 128348RBR-0070, dark brown alligator is the choice of aesthetic continuity. Vegetable-tanned alligator with naturally developed patina expresses cohesion with the precious metal. For a sport-formal context, vulcanised black rubber offers constant grip. Burgundy shell cordovan represents a bold choice for those desiring dramatic contrast.
How do I change the strap on a Rolex Day-Date?
The procedure requires a watchmaker to extract the horizontal suspension pins that bind the bracelet to the lugs. Do not attempt alone: the pins are small and improvised tools damage the case. Some specialised artisans offer strap-change service following watch delivery. At Casati Milano, it is possible to coordinate fitting directly on the client's watch.
Is an aftermarket strap compatible with the 128348RBR-0070?
Yes, provided it is constructed specifically for 20mm lug width with internally calibrated passants. Generic straps labelled '20mm' may present insufficient manufacturing tolerances. We recommend ordering from specialised artisans who test fitting before shipping. Milanostraps.it offers 20mm straps verified for Rolex compatibility.
How long does a leather strap last on a Rolex watch worn daily?
Durability depends on material, tanning method and frequency of wear. Vegetable-tanned alligator resists 3–4 years of daily wear before requiring restoration. Vegetally tanned calf lasts 2–3 years. Shell cordovan, extremely resistant, exceeds 5 years. Deterioration accelerates if exposed to humidity, intense perspiration and direct sunlight. Quality artisan straps can be restored or regenerated, extending life indefinitely.
