The Rolex Sky-Dweller collection is all housed in a 42mm case, following Rolex’s recent trend of larger watches and feeling bigger thanks to its wide lugs. 
Of the three precious metal models launched in 2012, the 18K white gold Sky-Dweller ref. 326939 became the most sought-after, but for many watch enthusiasts, any version of the watch is an acquired taste. This unique dial has generated the most opinions and controversy, especially the open GMT display.
While arguably easier to read than their other dual time zone creations, the GMT-Master II and Explorer II, the off-centre 24-hour dial is a far cry from replica Rolex’s standard. The white colour of the subdial against the ivory satin of the 326939 is a subtle feature that adds more appeal to this variant. Compared to the stellar gold and yellow gold offerings, the white gold model has a more casual aesthetic.
On the completely monochromatic face, the only colour is the inverted red triangle above the disc, which shows the time of return home when you are on a trip.
A small hole above each hour marker indicates the month. Fortunately, there are as many months in a year as there are hours, so on Sky-Dweller, the black window at 12 o’clock tells you it’s December, January at 1 o’clock, and so on. The high contrast makes it extremely easy to read. The date is linked to the local time, set on the main central hand, and changes instantaneously at midnight.
When Rolex launched the Sky-Dweller ref. 326939, the replica watch came with a silver dial and Roman numerals in white gold. However, two years later, in 2014, Rolex expanded the dial options of the Sky-Dweller collection. The white gold Sky-Dweller then began to come with a black dial with Arabic numerals and a white 24-hour disc.
Finally, a few years later, in 2017, Rolex redesigned all Sky-Dweller dials, including reference 326939, to feature luminous baton indicators and dropped the Arabic and Roman numeral options. Subsequently, the Sky-Dweller 326939 was available with a black, white or blue baton dial. However, these are very rare, as Rolex discontinued production of the white gold Sky-Dweller the following year.
