CASIO W-800H-2A 44mm Blue Resin Digital Men's Watch

The Casio W-800H-2A is a men's blue resin digital watch with a square 44 mm case and 100-meter water resistance. It suits everyday wear, outdoor work and water sports, and the clear black display plus LED backlight make time checks easy in low light.

The Casio W-800H-2A digital watch runs on quartz movement, so it keeps time without winding. Its black digital display shows hours, minutes, seconds, date and day, and an LED light brightens the screen when needed. The blue resin strap fastens with a buckle clasp and adjusts through several holes for a range of wrist sizes. Resin keeps the case and strap light, and the material is hypoallergenic. The watch is rated for swimming and snorkeling, though not diving.

Key features and benefits of the Casio W-800H-2A

• 100-meter water resistance: The case is rated to 100 meters, so you can swim, snorkel or shower without taking the watch off. It is not intended for scuba diving.
• LED backlight: A dedicated button switches on a light behind the display. This makes the digits readable in darkness or dim rooms without another light source.
• Quartz movement: A battery-powered quartz movement keeps time without winding. It is accurate to within seconds per month until the battery needs replacing.
• 44 mm resin case: The square case measures 44 mm across and is made from resin, a light synthetic material. Resin resists scratches, impacts and corrosion better than many metals, which helps in daily wear.
• Blue resin strap: The blue strap matches the case and is flexible and hypoallergenic. Several holes let you adjust the fit across a wide range of wrist sizes.
• Square case shape: The square profile gives the Casio W-800H-2A a modern, practical look. It also leaves more room for the display than a round case of similar width.
• Black digital display: High-contrast digits on the display show time, date and day. The layout is simple to scan when you need a quick time check.
• Date and day display: The watch tracks the calendar and shows both the date and the day of the week. It adjusts for months with fewer than 31 days, so you do not need to reset it each month.
• Buckle clasp: A pin buckle secures the strap and is easy to fasten with one hand. It holds the watch in place during activity.
• Alarm and stopwatch functions: The digital module includes alarm and stopwatch functions for basic daily timing. These are simple tools for reminders or timing short activities.
• One-year warranty: Casio covers defects in materials and workmanship for one year from purchase. The warranty does not cover accidental damage or misuse.

Using and caring for the Casio W-800H-2A

The resin case and strap are light and comfortable for long wear. After swimming in salt water or a chlorinated pool, rinse the Casio W-800H-2A watch with fresh water and dry it with a soft cloth. Do not press the buttons underwater, because that can force water past the seals. Have a watch technician replace the battery to help keep the water resistance intact.

• Clean the case and strap with a soft damp cloth, and avoid solvents.
• Check the strap holes for wear and replace the strap if it cracks.
• Press the light button only when needed to conserve battery life.
• Schedule battery replacement every 2-3 years with a watch technician.
• Keep the watch away from solvents, perfumes and harsh chemicals.

How to choose the right watch

When you choose a digital watch, case size, water resistance, display clarity and strap comfort matter most. The Casio W-800H-2A has a 44 mm square resin case that suits medium to large wrists, 100-meter water resistance for swimming and snorkeling, a black digital display with an LED backlight, and a flexible blue resin strap with several adjustment holes. Its quartz movement keeps time without charging. If you want a smaller case, a metal band or smartwatch sensors, another type of watch may fit better.
