Rolex Sky Dweller 42

Description

High-flying

The Oyster Perpetual Sky-Dweller in Oystersteel and yellow gold with an intense white dial and an Oyster bracelet. m336933-0005

Intense white dial
A striking characteristic
A fixed inverted red triangle on the dial points to the chosen reference time – the time at home or at the traveller’s usual workplace – on the off-centre 24-hour disc. At a glance, this 24-hour display clearly distinguishes daytime hours from night-time hours in the other time zone.

A deep red rectangle in one of the 12 windows around the dial indicated the current month, a striking characteristic of the Saros annual calendar. This ingenious mechanism simplifies life for the wearer of the watch, who no longer needs to think about adjusting the date at the end of a 30-day month. The annual calendar displays the correct date through the year. Only one adjustment is needed – on 1 March (February having only 28 or 29 days). The date is connected to local time and automatically changes according to the traveller’s local time zone.

The Fluted Bezel
A Rolex signature
The Rolex fluted bezel is a mark of distinction. Originally, the fluting of the Oyster bezel had a functional purpose: it served to screw the bezel onto the case helping to ensure the waterproofness of the watch.

It was therefore identical to the fluting on the case back, which was also screwed onto the case for waterproofness, using specific Rolex tools. Over time, the fluting became an aesthetic element, a genuine Rolex signature feature. Today the fluted bezel is a mark of distinction, always in gold. The Sky-Dweller is equipped with a mechanism of interaction between the rotatable bezel, the winding crown and the movement: the Ring Command system, which allows the user to select the watch’s functions one-by-one and to set them easily, quickly and securely.

Yellow Rolesor
A meeting of two metals
Gold is coveted for its lustre and nobility. Steel reinforces strength and reliability. Together, they harmoniously combine the best of their properties.

A true Rolex signature, Rolesor has featured on Rolex models since the early 1930s, and was trademarked as a name in 1933. It is one of the prominent pillars of the Oyster collection.

The Oyster bracelet
Alchemy of form and function
The Sky-Dweller is fitted on a solid-link Oyster bracelet in Oystersteel, in the case of the white Rolesor version, or, for the yellow Rolesor version, an Oyster bracelet combining Oystersteel and yellow gold.

The Oyster bracelet benefits from the new concealed attachment system beneath the bezel which ensures seamless visual continuity between the bracelet and case. It is equipped with a folding Oysterclasp and also features the ingenious Rolex-patented Easylink rapid extension system that allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.
