CASIO G-SHOCK GBD-200UU-9DR G-SQUAD URBAN UTILITY DIGITAL GREY WATCH

Does it have GPS?

Not in the watch. Distance, speed and pace are calculated from an accelerometer, which reads your arm motion. What the watch does offer is GPS distance correction through the app — if you carry your phone, the app can use its GPS to correct the distance figure afterwards, which brings the numbers closer than the accelerometer manages alone. The watch will not map your route, and without your phone the distance remains an estimate from your stride.

What is a memory-in-pixel LCD, and why does it matter?

It is a display that controls every pixel individually rather than lighting fixed segments, so it can show more information at once and keep it sharp — the reason the training screen can carry several figures legibly and be rearranged to your preference. For low light there is a Super Illuminator LED with an afterglow, set to 1.5 or 3 seconds, plus an auto light switch that lights the display when you tilt your wrist to read it, which is the detail that counts mid-run.

What training functions does it have, and how much does it store?

Distance, speed, pace and calories, with lap times taken automatically or by button, and Auto Pause to stop the measurement when you stop moving. You can set target alerts for time or calories, and the training display can be rearranged to suit you. Memory holds up to 100 runs of up to 140 laps each, so a season's training sits on the watch rather than needing a sync after every session. Outside training, the life log keeps your daily step count and monthly running distance.

What else does the phone link do?

It pairs with the free CASIO WATCHES app and connects automatically. The app sets the time for you, forwards phone notifications, keeps your activity history and life log, and includes a phone finder. The watch itself holds 38 time zones with automatic summer time switching, so it keeps working sensibly when you travel whether or not your phone is to hand.

Can I swim with it, or wear it in the rain?

Yes to both. 200-metre (20 BAR) water resistance covers swimming, snorkelling and surface water sports, and sweat and rain are no concern at all. It is not a scuba diving watch — the rating is a laboratory pressure measurement rather than a depth you should descend to — and you should not press the buttons while the watch is submerged.

Will it fit my wrist?

Casio does not publish a compatible band size for this model, so we cannot quote a wrist range. It is a full-size sports case at 48.4 × 45.9mm and 15mm thick, but light at 58 grams, which is what matters most over a long run. The resin band fastens through holes with no in-store sizing step, so it is worth trying one on if you are unsure about the size.

Does it charge from light, and how long does the battery last?

There is no solar charging on this reference. It runs on a CR2032 battery for approximately two years, holding ±15 seconds per month on its own — and with the mobile link active, the app corrects the time for you anyway. When the battery runs down, bring the watch to any City Chain outlet; having it changed by a service centre keeps the case seal correctly reseated, which protects the 200-metre rating.

What warranty does this watch come with?

The GBD-200UU-9DR comes with Casio's official 1-year warranty when purchased from City Chain Singapore, an authorised Casio retailer.
