The Heritage

The Day-Date was introduced in 1955 as the first wristwatch to display the day and date in full. It is powered by the automatic calibre 3255 with chronometer certification and functions for hours, minutes, seconds, date and day. The case measures 36mm and features 20mm lugs.

FAQ

What is the lug width of the Rolex Day-Date 36 128345RBR-0053?

The lug width of the Rolex Day-Date 36 in Everose Gold (128345RBR-0053) is 20 millimetres. This measurement is specific to all Day-Date 36 models and is determined by the distance between the two lugs where the strap connects via spring bars. Do not confuse this with wrist circumference: 20mm remains constant regardless of personal fit dimensions.

Which strap material is most suitable for the Rolex Day-Date 36 128345RBR-0053?

For the Day-Date 36 in Everose, alligator leather represents the maximalist aesthetic choice: natural grain texture pairs exceptionally well with rose gold's warm tone. Alternatively, vegetable-tanned calf offers vintage character and develops patina over time. Shell cordovan in cognac or burgundy amplifies the Everose warmth, whilst black alligator creates formal contrast ideal for evening occasions. Selection depends on intended use and personal style preference.

How do you change the strap on a Rolex watch?

Changing the strap on a Rolex Day-Date 36 requires specific tools: a spring bar tool and a soft surface to protect the case. Position the watch face-down, locate the spring bar retaining pin laterally, gently depress it with the tool to release one lug, then remove the old strap. Reverse the process to install the new strap. If uncertain, an authorised Rolex service centre can perform this operation in minutes.

Is an aftermarket strap compatible with the Rolex Day-Date 36 128345RBR-0053?

Yes, any strap with a 20mm lug width is technically compatible with the Day-Date 36 128345RBR-0053. However, quality and longevity vary significantly: an artisanal strap in alligator or shell cordovan represents an investment worthy of the timepiece, whilst budget synthetic leather may degrade rapidly. We recommend vegetable-tanned leather or natural reptile leather to ensure longevity and aesthetic consistency.

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

Strap longevity depends on material quality, tanning method, and intensity of wear. A high-quality alligator or shell cordovan strap with vegetable tanning, worn daily, typically resists visible deterioration between 3 to 5 years. Vegetable-tanned calf tends to last 2 to 3 years under intensive conditions. Proper care—avoiding prolonged sun and moisture exposure, regular cleaning with soft cloth—significantly extends strap lifespan. Premium artisanal straps develop patina that enhances their appeal over time.
