CASIO MWD-110H-3A Dark Green Resin Square Men's Digital Watch

The CASIO MWD-110H-3A is a men's square digital watch with a dark green resin case, a matching resin strap and a 47mm case. Its black dial and simple button layout suit everyday wear, travel and light sport, while the resin build keeps the watch practical for daily use.

The CASIO MWD-110H-3A men's square digital watch runs on quartz movement and includes world time for 29 zones and 48 cities, a stopwatch that reads to 1/100 second, a daily alarm, an hourly signal, a full auto calendar and an LED backlight. A mineral glass crystal protects the display, and 100 metre water resistance covers swimming and snorkelling. The dark green resin strap uses a stainless steel buckle and stays flexible in heat and cold.

Key features and benefits of the CASIO MWD-110H-3A

• 47mm square resin case: The case is moulded in resin with an angular square shape. Resin resists knocks and scratches, and the flat profile sits close to the wrist under a shirt cuff.
• Dark green resin strap: The strap matches the case and closes with a stainless steel buckle. Resin remains flexible in heat and cold, so the fit stays comfortable through the day.
• World time for 29 zones and 48 cities: The module can show the time in another city from a list of 48 cities across 29 time zones. One button press switches between home time and the selected zone, which helps on trips or when working with people abroad.
• 1/100-second stopwatch: The chronograph measures up to 24 hours and includes split and lap modes. It lets you time intervals during runs, swims or circuit sessions.
• Daily alarm and hourly signal: You can set one daily alarm and switch on an hourly chime. The chime works as a quiet pace keeper in meetings or study sessions.
• Full auto calendar to 2099: The calendar adjusts for month lengths and leap years until 2099. You do not need to correct the date by hand at the end of shorter months.
• LED backlight: A light button illuminates the digital display in green. The glow makes the digits easier to read in a dark room, tent or car at night.
• 100 metre water resistance: The case is sealed to 10 bar, which covers swimming, snorkelling and surface water sports. It is not rated for scuba diving.
• Quartz movement: The battery-powered quartz module keeps time within plus or minus 30 seconds per month. Battery life is about three years under normal use.
• Mineral glass crystal: The flat mineral crystal resists everyday scratches better than acrylic. It also costs less to replace than sapphire.
• Black digital dial: The display sits against a black dial inside the dark green square case. Clear digits and a simple button layout make the time easy to read at a glance.

Who the digital watch is for

The CASIO MWD-110H-3A is aimed at men who want a rugged digital watch for daily wear, travel and light sport. Its square 47mm case and dark green resin build give it a functional look, and the world time, alarm and stopwatch cover common timing tasks. The watch suits people who value clear digits and simple controls over a dressier metal finish.

• Commuters who need quick time-zone checks and a reliable alarm
• Outdoor enthusiasts hiking, camping or kayaking where 100m water resistance matters
• Gym-goers timing intervals with the 1/100-second stopwatch
• Students or shift workers using the hourly signal and calendar
• Anyone wanting a low-maintenance watch that survives knocks, rain and pool sessions

Less suitable if: you need a dress watch for formal events, a heart-rate monitor, GPS tracking or a metal bracelet for a heavier wrist presence.

Using and caring for the CASIO MWD-110H-3A

Rinse the watch with fresh water after salt water or chlorine exposure, then dry it with a soft cloth. Press the buttons only when the watch is dry so the case seal stays intact. Keep the module away from strong magnets and extreme heat, and have the battery changed by a qualified watchmaker who can reseat the gasket.

• Clean the resin strap with mild soap and a soft brush, and avoid solvents.
• Check the buckle pin regularly for wear, and replace it if it loosens.
• Do not operate the pushers underwater.
• Keep the module away from magnets such as speakers and phone mounts to prevent time drift.
• Have water resistance tested every two years if you swim frequently.

How to choose the right digital watch

Choosing a digital watch comes down to case size, water rating, function set and strap material. The CASIO MWD-110H-3A uses a 47mm square case that suits medium to large wrists, a 100 metre water rating for swimming, and a function set with world time and a 1/100-second stopwatch. Its dark green resin strap resists sweat and UV, while the mineral glass crystal handles everyday scratches. If you need a smaller case or a metal bracelet, this model is not the closest match.

Frequently asked questions

What is the CASIO MWD-110H-3A made of?

The case and strap are resin, and the crystal is mineral glass. The buckle is stainless steel.

How large is the case?

The square case measures 47mm across, not including the pushers. Its corners extend beyond the dial, so it wears larger than a round watch of the same measurement.

Can I swim with the CASIO MWD-110H-3A?

Yes. The 100 metre water resistance rating covers swimming, snorkelling and surface water sports, but it is not rated for scuba diving. Do not press the buttons underwater.

How does world time work on this watch?

World time covers 29 time zones and 48 cities. You can switch between home time and a selected city with one button press, though only one zone shows at a time.

How accurate is the stopwatch?

The stopwatch reads to 1/100 second for the first hour and then to 1 second up to 24 hours. Split and lap times remain stored until you clear them.

What battery does the watch use?

A CR2016 lithium cell powers the module, and battery life is about three years with normal alarm and backlight use. Have a qualified watchmaker replace it so the gasket is reseated correctly.

Is the resin strap adjustable?

The strap has multiple holes and a stainless steel tang buckle. It fits wrists from roughly 150mm to 210mm circumference.

How does the CASIO MWD-110H-3A differ from other digital watches?

This model pairs a 47mm square resin case and dark green colour with world time, a 1/100-second stopwatch and 100 metre water resistance. Some digital watches use round cases, leave out world time or carry a lower water rating.
