Oyster Perpetual Sky-Dweller: Mastering Travel Time

Oyster Perpetual Sky-Dweller: Mastering Travel Time

Jan 25th 2024

Rolex is a catalyst for horological innovation. Since its founding nearly 120 years ago, the brand has registered over 400 patents, including the Oyster, the world’s first waterproof wristwatch. This penchant for patenting continued with the introduction of the Oyster Perpetual Sky-Dweller, Rolex’s most complicated timepiece. The Sky-Dweller is a traveler’s dream timepiece, equipped to display two time zones simultaneously in addition to date and year indicators that need to be adjusted only once per year. Specs aside, these complications add aesthetic elements that are altogether unusual and refreshing. With increased durability thanks to the introduction of steel, the Sky-Dweller is a traveler’s best companion.

Razny Jewelers is proud to be an Official Rolex Jeweler in Chicago and surrounding suburbs, offering historically iconic timepieces, such as the Sky-Dweller. Today, we’re taking a deep dive into the watch’s expert design and features.

Elegant and technically sophisticated, the Oyster Perpetual Sky-Dweller was designed for those continually travelling the globe. Featuring the Saros annual calendar and Ring Command system, it simultaneously indicates two time zones, as well as the date and month, and allows them to be adjusted with one simple gesture.

Since its creation in 2012, the Sky-Dweller has been aimed at those who see the world as a single territory, without borders. It allows travelers to avoid the pitfalls of time differences and always stay one step ahead.

Second Time Zone at a Glance

The Sky-Dweller simultaneously displays the time in a second time zone as well as the local time, which is indicated by central hands. This second time zone – or reference time – is indicated by a highly legible, small triangle with a red silhouette on a 24-hour graduated rotating disc. A signature element of the model, this off-center disc makes it possible to unequivocally distinguish between daytime and night-time hours: an invaluable asset for someone travelling to the other side of the world.

Innovative and intuitive annual calendar

Specially developed for the Sky-Dweller, the patented Saros annual calendar is a key element in the model’s identity. The name of this mechanism, with its innovative design, is inspired by the Greek term denoting the cycle of lunar and solar eclipses.

The Saros calendar automatically differentiates between 30-day and 31-day months. It therefore requires only one manual date adjustment a year, when February turns to March. It is intuitive and simple to read. The current month is indicated in red in one of the dozen windows that punctuate the hour markers around the circumference of the dial.

The watchmaking innovation relies on two-gear ratios and only four-gear wheels added to Rolex’s instantaneous date calendar. This elementary structure gives the Saros annual calendar excellent reliability.

Ring Command System: Time Under Control

Developed by Rolex, the patented Ring Command system is an innovative mechanism of interaction between the rotatable bezel, winding crown and movement. It allows the Sky-Dweller’s different functions to be selected easily, quickly and securely, before adjusting them with the winding crown.

By turning the fluted bezel counterclockwise – the profile of which is accentuated to make it easier to handle – the wearer chooses the indication that they wish to set. First notch: date and month. Second notch: local time. Third notch: reference time.
