Under the hood, the Casio F-91W-1DF Digital Watch utilizes a Module 593 quartz movement for standard timekeeping and date tracking. With a 21g resin construction, the build avoids wrist fatigue during long shifts. This Japanese Quartz model maintains ±30 seconds monthly accuracy using a single CR2016 cell.
The "Water Resist" rating handles light rain and sweat. Avoid submersion in pools or high-pressure water.
