Our review of the Casio W800HG Series finds it to be a straightforward, hardworking daily digital watch best suited to men who want long service life and simple reliability without bells and whistles. The single biggest reason to buy is the combination of a 10-year battery life and 100 meter water resistance, which together mean this watch can be worn for years with minimal maintenance. The interface is uncomplicated, the display is easy to read at a glance, and the LED backlight keeps it useful in low light.

Key Features

• 10-year battery: The CR2025 battery offers long-term use so you can wear the watch for years without battery changes, lowering total ownership fuss.
• 100 meter water resistance: Rated for 100 m, it handles rain, showering and swimming comfortably for everyday active wear.
• LED backlight: The illumination improves readability in dark conditions so the watch remains useful at night or under low light.
• Multi function alarm & countdown: The alarm and countdown timer cover basic timing needs for workouts, commutes or simple reminders.
• 100 sec stopwatch and dual time: The stopwatch and dual time features make it practical for timing runs and tracking a second time zone on trips.
• Auto calendar & setting save: The auto calendar and automatic save when leaving the setting screen protect your changes so you do not need to repeat setup steps.

Who It's For

The W800HG is aimed at buyers who want a low-maintenance digital watch for work, outdoor activity or everyday wear. It suits men who value durability, clear legibility and long battery life over premium materials or complex smart features.

It is less suitable for someone seeking an analog dress watch, fashion-forward design details, or smartwatch-style notifications and apps. If you need advanced sensors like GPS, heart rate or touchscreen interfaces, look elsewhere.
