- Does it need a battery change?
- No routine battery swap is needed. A solar cell charges from light and powers the quartz movement, and the rechargeable cell lasts years.
- How does radio control work?
- The watch receives atomic clock signals on multiple bands and corrects its time automatically, usually overnight. Reception depends on your distance from a transmitter.
- Is titanium better than steel here?
- Titanium makes it lighter and more comfortable for daily wear. Steel versions feel more substantial and resist scratches better.
- Is it good for swimming?
- It is rated for 100 m water resistance, which covers swimming and snorkeling but not diving.
- What is in the box?
- The watch, bracelet and documentation are included. No charging cable is needed since it runs on light.
- Does it work worldwide?
- Radio reception covers Japan, the US, Europe and China. Outside those regions it still keeps quartz time but will not auto-sync.
