The Heritage

The Datejust is one of Rolex's iconic models, introduced in 1945 as the first self-winding watch with date indication. It features the automatic caliber 3135 with official chronometer certification and functions of hours, minutes, seconds. The 36mm case has 20mm lugs and maintains the classic proportions of the collection.

FAQ

What is the lug width of the Rolex Datejust 36 reference 116244-0018?

The lug width is precisely 20 millimetres. This measurement represents Rolex's proportional design specification for 36mm Datejust models in two-tone configuration. To verify compatibility, measure the distance between the two metal lugs connecting the case to the strap using a digital calliper.

Which strap is most suitable for a Rolex Datejust 36 116244-0018 with mother-of-pearl dial?

Alligator leather in deep black is the most coherent choice to emphasise contrast with the silvery mother-of-pearl. Alternatively, cognac vitello will dialogue with the white gold case elements. For those appreciating visible ageing, shell cordovan offers extraordinary chromatic development over time.

How do you change the strap on a Rolex Datejust 36?

Strap replacement requires removal of the spring bars connecting the strap to the case. Use a dedicated spring bar tool to gently push the bar until one end liberates, then extract the old strap. Insert the bars into the new strap, align, and reinsert the bars into the case until engagement click.

Is an aftermarket 20mm strap compatible with the Rolex Datejust 36 116244-0018?

Yes, provided the lug width is genuinely 20 millimetres. Caution: some manufacturers use undersized lugs (19.5 mm) to reduce production costs. Always verify measurement with digital calliper before purchase to avoid lateral play or installation impossibility.

What is the average lifespan of a leather strap on a Rolex Datejust 36?

A quality leather strap (alligator, vitello, shell cordovan) has average lifespan of 4–7 years with daily use, depending on UV exposure, humidity, and cleaning frequency. The mother-of-pearl requires no particular maintenance, but leather contact points naturally wear and periodically require regeneration by specialised craftspeople.
