The newAstron GPS Solar 8X42will be released this coming September to complete the series of four Astron GPS Solar caliber watches launched bySeiko. Like the rest of the range, the 8X42 allows you to adjust to local time, in any corner of the planet, with the push of a button using solar energy. It features a large date window, a second time zone dial at the six o'clock position, and new, slightly thinner hands. Its modern design with refined lines makes it the perfect watch for all occasions, whether it is evening events or international travel.

And for the first time, Seikohas incorporated into the design of the Astron elements that can be considered a “dressable Astron”, such as Roman numerals and components with mirror-finished surfaces.

The 8X42 collection is completed with a very special limited edition, developed in honor of Seiko's great friend, Novak Djokovic, one of the few tennis players in the world who has managed to win all four Grand Slams.

It shows an elegant and sophisticated design, with a sporty air that reflects the passion that characterizes this great athlete. The names of the four host cities of the tournaments, London, Melbourne, New York and Paris, are present on the yellow-tone bezel, the striped pattern on the dial offers a discreet reflection of how the grass on the court is cut and the tennis scores, 15, 30 and 40, surround the secondary dial with a discreet and ingenious design.

It is therefore a durable and intelligent watch that proudly bears Novak Djokovic's signature and individual serial number on the caseback. A bezel made of zirconia ceramic and a resistant and flexible silicone strap complete this magnificent Astron whose intelligent technology and precision place it among the elite of watches.
