In Context

At 40 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. 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. 70 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.

126715CHNR-0001 is one of 2 executions of the 126715CHNR base reference. Underneath they are the same watch; what separates this one is a black dial and a rose gold case. Introduced in 2018. Beyond the time it carries a gmt.

The 3285 is the GMT-Master II movement since 2018: the Chronergy generation with a second time zone, ten patents and a 70-hour reserve. It powers 19 watches in this library. It is the [3235](/calibers/rolex-3235) architecture with a 24-hour hand: the Chronergy escapement, the blue Parachrom hairspring, Paraflex shock absorbers, 31 jewels and a beat of 28,800 vph at 28.5 mm across, with the local hour hand jumping independently in one-hour steps so a traveller sets it without stopping the watch. Every one is a Superlative Chronometer, tested to two seconds a day after casing. The glossary explains the [GMT](/glossary/gmt) distinction it sits on the "true" side of. In the library it powers 17 [GMT-Master II](/brands/rolex/gmt-master) references of the 1267xx generation, the Pepsi and Batman in steel, the Everose Root Beer and the yellow gold, and 2 Explorer II 226570s of 2021 at 42 mm. The [3186](/calibers/rolex-3186) is the 50-hour GMT movement it replaced, and the [9002](/calibers/rolex-9002) the Sky-Dweller's movement of the same generation.

18 other watches in the library run the Rolex 3285.
