Casio AE-1700H-1A Quartz Men's Digital Watch with LED Backlight

The Casio AE-1700H-1A is a quartz men's digital watch made for everyday wear, built around a large digital display that is easy to read at a glance. It pairs 100-metre water resistance with an approximate 10-year battery life, which suits anyone who wants a low-fuss watch for work, training and weekends.

The Casio AE-1700H-1A men's digital watch also carries the timing tools people reach for most: a 1/100-second stopwatch, dual time for a second zone, a 24-hour countdown timer and a multi-function alarm. An LED backlight lights the digits in the dark, and the full auto-calendar keeps the date correct through short months and leap years. You can set the display to 12-hour or 24-hour time, whichever way you read a clock. A 1-year warranty covering manufacturing defects is included with the watch.

Key features and benefits of the Casio AE-1700H-1A men's watch

• Large digital display: the digits take up most of the face, so one glance covers the time, the date or whichever function is running. That size helps when you are reading the watch in a hurry or in poor light.
• 100-metre water resistance: the watch is rated to 100 metres, which covers splashes, rain and a swim in the pool. Keep the buttons untouched while you are underwater so water cannot get past the seals.
• Approximate 10-year battery life: the cell is expected to run for around a decade, so battery changes are rare. Real life depends on how often you use the backlight, alarm and timer.
• Quartz movement: a battery-driven quartz crystal keeps the time, the standard setup for accurate, low-maintenance everyday watches. There is no winding to remember.
• 1/100-second stopwatch: it times short efforts to the hundredth of a second, which is finer than a whole-second timer. That suits sprint splits, interval sets or any task where fractions count.
• Dual time: a second time zone sits alongside your home time, useful when family, clients or colleagues are in another country. You can check their working hours without doing the maths.
• 24-hour countdown timer: it counts down from a set period of up to 24 hours in one run. Cooks, coaches and anyone working to a deadline can watch the remaining time on the display.
• Multi-function alarm: the alarm sounds at the time you choose, so it works as a wake-up call or a nudge before an appointment. Setting it takes a moment and it repeats daily.
• LED backlight: a button press lights the display so the digits stay readable in a dark room, a tent or a cinema. Short presses keep the demand on the battery low.
• Full auto-calendar: the watch accounts for different month lengths and leap years on its own. The date stays right without you adjusting it at the end of each month.
• 12/24-hour format: switch between the two readings to match your habit, with 24-hour useful for timetables and travel. The setting is yours to change whenever you like.

Who the Casio AE-1700H-1A men's digital watch is for

The Casio AE-1700H-1A suits men who want one watch to cover the whole week rather than a drawer of single-purpose pieces. The digital face reads clearly, the 100-metre rating means everyday water contact is not a worry, and the long battery life keeps maintenance to a minimum. It works as a first proper watch, a training companion or a practical everyday piece for someone who spends time outdoors, on shift or travelling between time zones.

• Daily wear at work, where a clear digital readout and a date you never reset are the main draw.
• Swimming, pool sessions and beach days, thanks to the 100-metre water resistance rating.
• Interval training and timed circuits, using the 1/100-second stopwatch and countdown timer.
• Travel or shift work, with dual time showing a second zone at a glance.
• Early starts and tight schedules, where the alarm and backlight do the work.

Less suitable if: you dive or need a watch rated for scuba, since a 100-metre rating is aimed at swimming and everyday water contact rather than diving, or if you simply prefer the look of analog hands on your wrist.

Using and caring for the Casio AE-1700H-1A men's watch

The Casio AE-1700H-1A is designed to be worn and largely forgotten, so most care comes down to water and heat. Rinse the case with fresh water after a swim in the sea or a chlorinated pool, then dry it with a soft cloth. Keep the buttons dry while you are in the water, and leave the watch off your wrist in a sauna or hot shower, since heat is harder on seals than cold water.

• Press the backlight button briefly rather than holding it, and the battery drain stays modest.
• Set the alarm and countdown timer before an early start or a timed session, so you are not adjusting them in a hurry.
• Wipe the case and strap with a damp cloth when they pick up sweat or sunscreen, then let them air dry.
• Check the water resistance seals after any knock to the case, and avoid pressing buttons while submerged.

How to choose the right men's digital watch

Four things decide whether a digital watch earns its place on your wrist: water resistance, battery life, the functions you will actually use, and how easily you can read the display. The Casio AE-1700H-1A is rated to 100 metres, so swimming is covered. Its battery is expected to last around 10 years, which keeps servicing rare. It carries a stopwatch, countdown timer, dual time, alarm and full auto-calendar, covering the timing jobs most people need. The large digital face with LED backlight is built for quick reading, day or night.
