Key Features
- Eco-Drive Technology: This watch is powered by Citizen’s proprietary Eco-Drive system, which converts any light source into energy to power the watch. This eliminates the need for battery changes and ensures reliable performance as long as it’s exposed to light. Whether you’re indoors under fluorescent lighting or outdoors in natural sunlight, your watch remains fully charged and ready for use.
- 12/24-Hour Time Display with Day and Date: The dial offers clear readability with the option to switch between 12-hour and 24-hour time formats, catering to personal preference or international travel needs. The day and date complication is prominently displayed, providing at-a-glance convenience for scheduling and daily planning.
- Chronograph Functionality: Equipped with a precise chronograph, this watch allows you to measure elapsed time with accuracy. Ideal for timing workouts, events, or daily tasks, the stopwatch feature is both practical and easy to operate, enhancing the watch’s utility beyond standard timekeeping.
- Luminous Hands: The watch features luminous hands that absorb light and glow in low-light conditions, ensuring visibility in the dark or dimly lit environments. This practical feature enhances usability during nighttime activities or in poorly lit spaces without compromising the watch’s classic aesthetic.
