The Oyster Perpetual Sky‑Dweller was designed for those continually travelling the globe. Featuring our 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 an invaluable tool for avoiding the pitfalls of time differences and making it possible to plan ahead. With this technical and elegant watch, wherever you travel, you are in sync with the world.
