CASIO WS-1400H-3A Grey Dial Square Resin Men's Watch

The Casio WS-1400H-3A is a men's square resin digital watch with a grey dial, made for everyday wear, travel and light water sports. Its quartz movement, 100 metre water resistance and dual time display give you a practical timepiece that needs little attention.

The watch pairs a black resin case with a black and blue resin strap, so the square profile stands out without feeling heavy on the wrist. A 44 mm case gives the Casio WS-1400H-3A a bold look that still suits most men's wrists. The grey LCD (liquid crystal display) dial keeps the time, date and function indicators easy to read, while an LED backlight helps in low light. A stopwatch times events up to 24 hours, and the dual time setting keeps a second zone on hand for travel or work calls. At roughly 40 grams, the resin build is light enough for all-day wear.

Key features and benefits of the Casio WS-1400H-3A

• Quartz movement: A battery-powered quartz calibre keeps time without winding, and Casio rates it to within a few seconds per month. The battery typically lasts several years, so routine ownership is simple.
• Resin case and strap: Both parts are moulded from synthetic resin, a lightweight material that resists scratches. The build keeps the watch comfortable for long wear and easy to wipe clean.
• Square 44 mm case: The case measures 44 millimetres across its widest point and has a square outline. It gives the watch a retro-digital look with a bold presence on medium to larger wrists.
• Grey dial: The grey face gives the digital numerals strong contrast. You can read the time in bright daylight or indoor light without tilting the watch.
• Black and blue colour scheme: The black case is paired with a black strap that has blue accents. The two-tone finish adds a sporty note that works with casual clothes.
• 100 metre water resistance: The watch is rated for pressure equivalent to 100 metres of depth. You can wear it for swimming, showering and hand washing, though it is not intended for scuba diving.
• Dual time function: A second time zone can be set alongside the main time. Travellers and anyone working with people abroad can check both zones without changing the main setting.
• Stopwatch: The chronograph counts elapsed time up to 24 hours, with 1/100-second precision for the first hour. It suits interval training, cooking and timing tasks where you need a clear start and stop.
• Lightweight construction: The all-resin build weighs roughly 40 grams. That low weight helps the watch stay comfortable through a full day, including workouts and commutes.
• Digital display with LED backlight: The LCD shows time, date and function markers, and an LED light illuminates the screen in low light. The backlight makes the watch usable at night or in a dim room.
• One-year warranty: Casio covers defects in materials and workmanship for twelve months from purchase. It gives you support during the first year of ownership.

• Travel where you need home and destination time zones on one watch
• Swimming, showering or hand washing thanks to the 100 metre water resistance

Using and caring for the Casio WS-1400H-3A

Rinse the Casio WS-1400H-3A with fresh water after swimming in a pool or the sea, then wipe it dry with a soft cloth. For routine cleaning, use a damp cloth and mild soap on the resin case and strap, and avoid solvents or abrasive cleaners that can dull the surface. Press the buttons only when the watch is dry so the seals stay in good condition. Store the watch away from extreme heat and strong magnetic fields, which can affect quartz timekeeping.

• Rinse with fresh water after contact with salt water or chlorine
• Clean the resin case and strap with a damp cloth and mild soap
• Operate the buttons only when the watch is dry
• Keep the watch out of prolonged direct sunlight to limit resin discolouration
• Have the battery replaced by a qualified watch technician to help preserve water resistance

How to choose the right men's digital watch

When you choose a men's digital watch, start with case size, case material, water resistance and the functions you actually use. The Casio WS-1400H-3A has a 44 mm square case that suits medium to larger wrists, and its resin case and strap keep the weight low. A 100 metre water resistance rating covers swimming and showering, while dual time and a 24-hour stopwatch handle travel and timing tasks. If you need a smaller case, a metal bracelet or extra sensors, this model is not the closest match.
