In lieu of the micro-mechanical marvels we usually present in print and on this website, today’s timepiece embraces the digital end of the spectrum, and is chock full of the technologies associated with it.The G-Shock family of watches is quite simply universal, given its renown and ubiquity. From the simpler DW-5000s series to the flagship models, Casio has always featured G-Shocks’ toughness as a platform on which other features are then layered. The GPW-1000 here ups the ante by introducing a new system that betters its timekeeping, without scrimping on the staples G-Shocks are known for.

The heart of the GPW-1000 is a new system that adjusts the watch’s time via GPS satellite signals, and radio wave time calibration signals sent from six terrestrial stations worldwide. The use of two signal sources confers several benefits. Firstly, a user can adjust his watch via radio signals if he’s in range, even if he cannot receive GPS signals because he’s indoors or being blocked by objects. On the other hand, access to GPS signals pinpoints his location for adjustments based on his current time zone, with automatic daylight saving time adjustments as well. Lastly, the signals can be prioritised – radio signals, being more localised, over GPS signals when available.

To accomplish this, Casio has engineered the GPW-1000 to overcome the technical challenges a hybrid system poses. For one, the watch movement is driven by ultra-small motors that minimise space and power consumption. Coupled with the new low power consumption GPS LSI and a high efficiency solar power cell, the result is a watch that can run for up to 18 months on a full charge with its power saving function activated.

Naturally, the usual gamut of G-Shock watches’ features have been loaded into this one as well. A second time zone, stopwatch with split timer, countdown timer, alarm, and fully automatic calendar are all in. Together with a 200 metre water resistance and the usual shock, centrifugal and vibration resistance, this is possibly the most accomplished all-rounder from the family yet.
