- Does it really never need a battery change?
- Tough Solar charges from light through the dial, so under normal exposure it runs without battery swaps. In very dark storage the charge can drop, and the cell eventually ages like any rechargeable.
- How does atomic timekeeping work here?
- Multi-Band 6 receives time signals from transmitters in several regions and corrects the watch automatically, usually overnight. Reception is best near a window and can fail in some locations.
- Is it too big for a smaller wrist?
- At 45 mm with a steel band it wears large and heavy. Shoppers with slim wrists often prefer a resin G-Shock or a smaller MT-G model.
- Can I swim or dive with it?
- Yes. It is rated to 200 m and shock resistant, so swimming and water sports are fine. It is not a dive computer and has no depth gauge.
- What features does it have beyond time?
- World time, a stopwatch, countdown timer, multiple alarms, a full auto calendar and a backlight. It has no Bluetooth or app connectivity.
- How does it compare with a resin G-Shock?
- It adds a steel case and band plus solar and atomic timekeeping. A resin model is lighter and cheaper in feel but lacks the metal finish.
