You might think, as long as you have a watch on your wrist or a phone in your pocket, you've got a pretty good idea of the time. Casio, however, has proven otherwise. Human inconsistencies, mechanical deficiencies and minute delays in the sending and receiving of signals mean that most timepieces measure time differently, leading to discrepancies and a lack of accuracy. Now the Japanese manufacturer has created what is regarded as the most accurate wristwatch on Earth – the G-SHOCK GPW-1000.

Using a combination of radio signals and GPS (depending on where you are), this flagship timepiece maintains near 100% atomic accuracy anywhere on Earth, essential for both aviation and emergency rescue. As such, it comes equipped with a highly scratch-resistant sapphire display, as well as shock- and vibration-resistant shielding for the internal mechanism. It also features a carbon resin bracelet, an innovative solar charging system that circumvents traditional batteries, and a longitudinal display that shows exactly where you are on the Earth's surface.

Needless to say, all of this is pretty impressive to carry around on your wrist. Priced at €795, the GPW-1000 comes in three colorways and is available from selected retailers across Europe. You can find your nearest one or learn more about how it works, right here.
