Seiko has launched a limited edition of a solar watch worn by Novak Djokovic, the best tennis player in the world.

The Astron GPS Solar Dual Time, created especially for the Serbian tennis star, allows the globe-trotting tennis ace to manage his time in the most efficient way possible.

The Novak Djokovic Limited Edition is available now at select Seiko outlets worldwide.

Over the last year, Djokovic has played in 20 tournaments in 20 cities in 12 countries. “Without his Astron GPS Solar Dual Time, which we created especially for him last year, he would have had to adjust his watch manually more than 60 times. With his Astron, however, all he needs to do is to touch a button and see his watch adjust to the local time automatically,” says Seiko.

Using just the power of light, every Astron GPS Solar watch connects to the GPS network and automatically adjusts, at the touch of a button, to every time zone on Earth, showing the time with a precision of one second every 100,000 years.

“With the new dual-time caliber, you can read not only the time where you are, but also the time in your home time zone on a simple 12-hour sub-dial with a separate AM/PM indicator,” says the company.

In addition, the day of the week is displayed in a retrograde display at the 2 o’clock position, with the date at the 4 o’clock position. Thanks to the electronic setting function in the crown, the watch is simple to operate.

With a brown dial and crocodile leather strap, the rose-gold colour highlights and the black ceramic bezel, the new Novak Djokovic Limited Edition combines sport and elegance.

Each watch has its own individual serial number and carries Novak’s signature on the case back. The watch is offered in a special presentation box, with a card carrying a personal message from Novak.

Yesterday, at the Barclays ATP World Tour Finals in London, UK, Djokovic was honoured as year-end ATP World Tour No. 1 presented by Emirates  for the fourth time in five years.

Chris Kermode, ATP Executive Chairman and President, presented Djokovic with the trophy in an on-court ceremony.
