The Casio G-Shock Gravitymaster GPW-1000, launched in 2014, was targeted at frequent travellers. Now, its successor, the GPW- 2000, is aimed at not only travellers but also the pilots who fly them to their destinations.

The GPW-2000 uses Casio's new Connected Engine three-way module, which is the world's first three-way time sync system, according to its maker.

Its predecessor uses both radio waves and GPS satellite signals to calibrate time. Now, in addition to radio waves and GPS signals, the GPW-2000 connects to time servers when the watch is paired with a smartphone via Bluetooth.

The time zones and daylight saving dataare automatically updated by the G-Shock Connected app (Android and iOS) to ensure accuracy at all times, according to Casio.

This app allows you to change time easily when you cross time zones - especially useful when you are in transit and stuck in an airport terminal where you can't get GPS signals out in the open.

The GPW-2000 has a Flight Log function that records location and time data when the watch's bottom right button is pressed. The location and time data will be displayed on a map in the app.

Design-wise, the GPW-2000 takes inspiration from its predecessor. However, it is a wee bit wider (by 1.2mm) but slightly thinner (by 0.6mm) and lighter (by 6g) than the GPW-1000.

Still, the watch is pretty big. It probably will look just right on the wrist of movie star The Rock.

It might not be a dress watch, but it is beautifully rugged with the watch face looking like cockpit indicators. All the numbers of the watch face, except 12, are indicated by 3D luminous markers. The main dial has 28 major cities in different time zones marked on it.

On the left of the watch face there is an inset dial that displays latitude at the nine o'clock position. At the six o'clock mark, there is a small window that shows the day of the week but will display longitude when the Flight Log function is activated.

Above this window, there is a subsidiary dial that shows the time for a second city, which comes in handy when you are travelling.

There are two buttons on both sides of the watch case. The right side has a crown between them.

Scratch-resistant sapphire glass with a non-reflective coating shields the watch face, while the watch bands are made of resin strengthened with carbon fibre.

As you might expect from a G-Shock watch, the GPW-2000 is shock-resistant, vibration-resistant, magnet-resistant and also water-resistant down to 200m.

The highlight feature has to be the Flight Log function. Press the lower right button for 0.5sec and your location will be logged and sent to the app. When you group these locations together, you get arrows showing your flight path.

It is pretty cool to see yourself "flying" from one location to another. This is not only great for pilots, but if you are on a road trip in, say, Australia, you can log the locations to see how far you have driven.

Using the G-Shock Connected app is so much easier than fiddling with the buttons or crown. For instance, to change the world time in the sub-dial, you have to pull out the crown and turn it so that the second hand points to the city initials on the bezel.

With the app, just tap on the World Time option, choose the city you want and watch the hands of the sub-dial change accordingly.

You do not need to worry about charging this watch, as the GPW-2000 uses Casio's Tough Solar high-capacity solar-charging system. On a full charge, it can last 23 months with its power-saving function turned on.

•Verdict: Whether you are a pilot, a frequent flier or an adventure seeker, the Casio G-Shock Gravitymaster GPW-2000 is a rugged, yet stylish, watch that will serve you for a long time.
