CASIO WS-1400H-1A Black Resin 100m Water Resistant Digital Watch

The Casio WS-1400H-1A is a black resin digital watch built for everyday wear, travel and light water activity. Its 43 g build keeps it comfortable on the wrist, while a 100-meter water resistance rating covers swimming and similar wet use. The watch suits anyone who wants practical timekeeping tools without a heavy or fussy design.

This black resin digital watch combines a resin case, bezel and band with resin glass over the display. The layout shows hour, minute, second, am/pm, month, date and day, and the full auto-calendar runs to 2099. A CR2025 battery is rated for 10 years, which reduces routine battery changes. Timekeeping accuracy is ±30 seconds per month, and you can switch between 12-hour and 24-hour formats. The watch also has a mute setting for button tones, useful in quiet rooms or meetings.

Key features and benefits of the Casio WS-1400H-1A

• Resin case and band: Resin covers the case, bezel and band, keeping the watch light and comfortable. It also resists everyday knocks.
• Resin glass: Resin glass protects the display from scratches without adding much weight. It suits daily wear around bags and desks.
• 100-meter water resistance: The 100-meter rating covers swimming and light water sports. It is not intended for diving.
• World time and dual time: These functions track more than one time zone. That helps on trips or when coordinating with people abroad.
• 1/100-second stopwatch: The stopwatch measures elapsed, lap and split times with 1/100-second precision for the first 60 minutes. It gives useful detail for workouts and events.
• Stopwatch memory: Up to 60 records store the start date, lap and split times, and lap or split number. You can review past timings later.
• Countdown timer: The timer runs from 1 minute to 24 hours in 1-minute or 1-hour steps. Auto-repeat helps with recurring intervals or reminders.
• Three multi-function alarms: Three alarms, one snooze alarm and an hourly signal help you keep to a schedule. They are useful for daily prompts and appointments.
• LED light with amber illumination: The LED light gives the display amber light in the dark. You can choose 1.5 or 3 seconds, and afterglow keeps it visible briefly after switching off.
• Full auto-calendar: The calendar is pre-programmed to 2099. You do not need to change the date at the start of each month.
• Accuracy and battery life: Timekeeping accuracy is ±30 seconds per month, and the CR2025 battery is rated for 10 years. That means fewer routine battery changes.
• Mute and 12/24-hour format: Button tones can be turned on or off, and time can show in 12-hour or 24-hour format. Both settings match the watch to your day.
