Rolex Sky-Dweller is one of the most practical watches you can think of, the perfect instrument for travelers or busy business people piece. It is a complex watch, with many functions, but not just for the fun of it. Indeed, as nice and mechanically interesting as a perpetual calendar can be, it has a rather subjective inherent purpose.

An annual calendar, however, which is much easier to develop and assemble, only slightly less precise and much more accessible, offers real added value, compared to a normal calendar. This is one of the functions of the Sky-Dweller. Add to that an extremely practical function for business travelers: the dual-time display, allowing you to keep track of home time when traveling or another time zone when you’re working with colleagues in another city/country for example.

We all love the beauty of an integrated perpetual calendar, however, this combination of annual calendar / dual-time makes the Rolex Sky-Dweller one of the most rational offers on the market.
