2014 Limited Edition 2014 Limited Edition


The Astron revolution forges ahead.

Astron, the revolutionary GPS Solar watch that changed timekeeping forever takes another leap forward by incorporating a chronograph within stunningly streamlined dimensions. Now renowned atomic clock precision, automatic time-zone adjustment and more intuitive operation are available within a timepiece the size of a mainstream multi-function watch — Introducing the Astron Chronograph 2014 Limited Edition.

The world’s first GPS Solar watch

By connecting to the GPS network, the new Astron adjusts at the touch of a button to your time zone* and, by taking all the energy it needs from light alone, never needs a battery change.
* Time zone data as of January 2014. Changes to time zones occurring after this date are not programed and manual time zone selection may be required.

First Astron


The Astron revolution continues with the addition of a chronograph that brings new levels of functionality to the Astron series and redefines what a GPS Solar watch can deliver.

30% smaller

The Astron Chronograph case is 30% smaller than other Astron timepieces and the same size as most mainstream multi-function watches thanks to energy-saving advances that enable the use of a smaller GPS antenna.



One-touch activation of the GPS function is now complemented by an electronic setting function in the crown that simplifies operation.
