- Is the GW-M5610U-1CF worth it over the older GW-M5610?
- The U version adds a brighter Super Illuminator LED, a larger display font and improved button layout. If you find the older model cheaper, it still offers solar and atomic sync, but the U is the better everyday watch.
- Does it need a battery change?
- No regular battery swap is needed. The Tough Solar cell charges from light and powers a rechargeable cell that typically lasts many years before service.
- How does atomic timekeeping work?
- The watch receives radio time signals from six transmitters worldwide and corrects itself, usually overnight. Reception is best near a window; it can fail in basements or far from a transmitter.
- Can I swim with it?
- Yes. It is rated to 200 meters, which covers swimming, snorkeling and showering. It is not a dive computer and should not be used for scuba diving.
- What is in the box?
- The watch, a resin band, and a manual. It ships charged enough to run, but Casio recommends exposing it to light before first use.
- When does its value improve?
- Square G-Shocks tend to be discounted during major sales events and around model refreshes. Watch for those windows if you are not in a hurry.
