CASIO G-SHOCK GA-B001CBR-1ADR ANALOG-DIGITAL BLACK MEN WATCH

Does it charge from light?

No — and this is worth checking before you buy, because several G-SHOCKs that look similar do. This reference has Bluetooth but no solar charging. It runs on two SR726W batteries for approximately two years, after which a service centre replaces them. Timekeeping holds to ±15 seconds per month on its own, and with the mobile link active the app corrects it for you anyway.

What does the phone connection add?

It pairs with the free CASIO WATCHES app and sets the time automatically, which is the main benefit — no adjustment when you travel or when the clocks change. The app also opens up around 300 world time cities against the 38 zones held on the watch, makes the settings easier to change on a screen than through the buttons, logs time and place, and can ring your phone to help you find it.

What is the Carbon Core Guard structure?

It is Casio's name for building the shock protection into a carbon-reinforced case rather than wrapping a conventional case in extra guards. The case and bezel are carbon and resin. The practical result is the one you can feel: a full G-SHOCK with shock-resistant construction, Bluetooth and two LED systems that still weighs only 51 grams.

Why does the minute hand move in steps, and what is the small dial?

The minute hand advances every 20 seconds rather than sweeping continuously, which is normal for this movement and conserves battery; running seconds appear in the digital display instead. The small dial indicates which mode the watch is in — timekeeping, stopwatch, timer and so on — rather than showing the day. There is also a hand shift feature: press a button and the hands swing clear of the digital window so you can read it without anything in the way.

How readable is it in the dark?

Two ways. Neobrite on the hands holds a glow after exposure to light, so you get some readability without pressing anything. Beyond that there is a double LED — a Super Illuminator lighting the analog face and a backlight for the digital display, both white, both with an afterglow, and you can set the illumination to run for 1.5 or 3 seconds.

Will it fit my wrist?

Casio lists a compatible band size of 145mm to 215mm, which covers most adult wrists. The case measures 42.5 × 46mm and 13.8mm thick, but at 51 grams it is light for a G-SHOCK of this size. The resin band fastens through holes, with no in-store sizing step needed.

Can I swim or snorkel with it?

Yes. 200-metre (20 BAR) water resistance covers swimming, snorkelling and surface water sports. 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.

What warranty does this watch come with?

The GA-B001CBR-1ADR comes with Casio's official 1-year warranty when purchased from City Chain Singapore, an authorised Casio retailer.
