The Citizen Sky AT8396-59L Promaster Sky combines a sporty blue dial with advanced functions for those who travel frequently or value maximum accuracy. The case and strap are crafted from Super Titanium.
This material is significantly lighter than stainless steel and has been specifically developed for intensive daily use. With a case diameter of approximately 40.5 mm, the watch remains comfortable to wear despite its extensive functions. Beneath the sapphire crystal, you’ll find several sub-dials, a date display and functions including a chronograph and world time.
The blue dial gives all the technical features a fresh look without losing the professional Promaster character.
The H804 movement makes the AT8396-59L particularly appealing to frequent travellers. The watch can receive radio-controlled time signals in Japan, China, Europe and the United States. Whenever reception is possible, the time is automatically corrected.
In addition, the watch features world time for 26 cities, making it much easier to switch to a different time zone. The perpetual calendar is designed to automatically account for varying month lengths and leap years up to the year 2100. A chronograph, day display and power reserve indicator are also included.
Thanks to Eco-Drive, all this technology is powered by light. With a water resistance rating of 10 bar, the watch is suitable for everyday contact with water and swimming. It is particularly the combination of a relatively modest size, low weight and extensive functions that sets this Promaster Sky apart.
This gives you a technical travel timepiece that is nothing

The watch strap can easily be shortened using the strap shortener we supply free of charge.
not only offers a wide range of functions, but is also comfortable enough for everyday wear thanks to the titanium construction.
