Frequently asked questions
Is this watch actually safe for diving or just splash-proof?
It is ISO 6425 dive-certified to 200m, which is the actual dive-watch standard. That means screw-down crown, rotating bezel, and pressure-tested case. Safe for recreational scuba diving, not just showering and swimming.
How does Eco-Drive work and do I ever need a battery?
Eco-Drive is Citizen's solar movement. Any light source (sun, lamp, even office fluorescent) charges the cell. A full charge runs the watch about 6 to 8 months in total darkness. You will not need to open the caseback for a standard battery swap for the life of the watch.
Will it look too big on a smaller wrist?
The case is 43mm wide and 14mm thick, but it wears smaller than the spec sheet implies because the lugs are short and curve down sharply. Wrists 6.75 inches and up wear it cleanly. Below that, it photographs large but still functions.
Can I replace the rubber strap with something else?
Yes. Lug width is 20mm, which is the most common watch-strap size on Amazon. NATO, leather, jubilee, and oyster bracelets all swap in with two spring-bar pins. Strap swaps are how most owners customize this watch.
Is the lume actually bright?
Yes. Citizen uses their proprietary luminous compound on the hour markers, hands, and bezel pip. After a few minutes near any light source it glows clearly for several hours, plenty for night reading and underwater visibility.
