Datejust II Blue Azzurro

In Context

At 41 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 12 mm it is a tall case, and it will catch on a cuff. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 48 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

116300-0004 is one of 4 executions of the 116300 base reference. Underneath they are the same watch; what separates this one is a blue dial and a stainless steel case. Introduced in 2009.

The 3136 is the Datejust II movement of 2009 to 2016: the 3135 with the Parachrom hairspring and Paraflex shock absorbers, for the 41 mm case. It powers 16 watches in this library, every one a 41 mm Datejust II. It has 31 jewels, a 48-hour reserve and a beat of 28,800 vph at 28.5 mm across, with a quick-set date, and every one is a COSC chronometer. Paraflex, introduced on the Day-Date II's [3156](/calibers/rolex-3156) in 2008, raised the movement's shock resistance over the standard [3135](/calibers/rolex-3135). In the library it powers all 16 [Datejust II](/brands/rolex/datejust-ii) references, the 116333 and 116334 in yellow and white Rolesor and the 116300 in steel. The Datejust 41 of 2016, on the [3235](/calibers/rolex-3235), replaced the watch and the movement together; the [Datejust size guide](/blog/the-datejust-by-size-28-31-36-and-41) places the two in the family.

15 other watches in the library run the Rolex 3136.
