Casio Sport Pro Trek PRW-61Y-3ER Watch

The Watch

Looking for a watch that keeps up with everything your day throws at you - work, workouts, and everything in between? Meet your perfect match. From Japanese watchmaker Casio, the Casio Sport Pro Trek PRW-61Y-3ER is built to be more than a timepiece - it's a daily companion packed with features. The watch itself is crafted from resin, giving it a case that's tough, shock-resistant, and built for the long haul - just like the mineral glass crystal protecting the dial. It measures 54.2 mm × 47.4 mm × 14.7 mm (length × diameter × thickness) and weighs just 53 grams, making it light enough to forget you're wearing it. Controlling all its functions is effortless thanks to the crown button and four pushers positioned at each corner of the case. The caseback also delivers 10 ATM water resistance - so you can keep it on for your swim sessions without a second thought. Simply put, this watch is as practical as it is capable.

The Dial

The khaki background of this dial displays the time both in analog and digital format. Depending on your preference, you can read the time either way. At the center, three gray and black hands sweep across the dial, tracking the gray minute railroad track along the edge. Bold hour markers line the dial's perimeter for clear, at-a-glance timekeeping. These elements are all legible even in low light, thanks to their Neobrite fluorescent coating. A digital display at the bottom of the dial shows the time in digital format, along with all the data from the watch's sport functions. A sub-dial between nine and eleven o'clock handles thermometer and barometer functions. The Casio brand name and collection title are printed in gray lettering.

Features

5 Daily Alarms
An audible alarm keeps you on schedule every day at your programmed time. This model features five independent alarms, giving you the flexibility to stay on top of all your important appointments.

Full Auto LED Lighting
When you tilt your wrist in low-light conditions, an LED automatically illuminates the dial.

Automatic Calendar
Once programmed, the automatic calendar always displays the correct date.

12/24-Hour Time Format
Display the time in either 12-hour or 24-hour format.

Barometer (260 / 1,100 hPa)
A dedicated sensor measures atmospheric pressure (range: 260 / 1,100 hPa) and displays it on screen as a symbol - so you can stay ahead of changing weather conditions.

Thermometer (-10°C / +60°C)
A sensor measures the ambient temperature and displays it in degrees Celsius (-10°C / +60°C).

Compass
A built-in directional sensor detects magnetic north.

Altimeter 10,000 m
A pressure sensor detects changes in atmospheric pressure and converts the result into an altitude reading, up to 10,000 m.

Cumulative Altitude
The Cumulative Altitude function adds up every meter gained on the ascent, giving you a quick and easy readout of your total elevation gain during a hike.

Altimeter Memory
Depending on the model, the watch can store up to 40 altitude data records, accessible at any time. Each record includes the measured altitude along with the date and time of the reading. In addition to the measured altitude, the altimeter also logs the maximum and minimum altitudes recorded during a session.

Automatic Hand Correction
The automatic hand correction checks the base position of the hands every hour and adjusts them as needed - whether due to misalignment from shocks or magnetic interference.

Button Beep On/Off
The button beep can be turned off using the mode button. Once disabled, no beep sounds when switching between functions. However, any programmed alarms or countdowns remain active even after the button beep is turned off.

Hand Shift Function
This function lets you move the hands out of the way when they obstruct the readout of the time, date, or stopwatch function.

Crown Button Lock
Locks the crown button to prevent accidental mode changes.

Smart Access Technology
Smart Access makes setting the watch fast and intuitive via an electronic crown. Functions like the stopwatch, countdown timer, alarm, and world time can all be adjusted with a simple press and turn.

Cold Resistance (-10 °C)
This watch also withstands temperatures down to -10 °C.

Solar Power
Solar cells provide autonomous, eco-friendly energy. Any surplus solar energy is stored in a rechargeable battery.

Stopwatch 1/100 sec - 24 Hours
Measures elapsed time to 1/100th of a second, for up to 24 hours. An audible beep confirms both the start and stop of the stopwatch.

Countdown Timers - 1/1 min - 1 Hour
For those who demand precision: countdown timers alert you to important or recurring events with an audible signal at the programmed date and time. You can set the timer in minutes, up to a maximum of 1 hour.

Water Resistance (10 bar)
Perfect for swimming and snorkeling: this watch is water-resistant to 10 bar (ISO 22810).

Automatic Time Sync via Radio Signal (EU, USA, JPN, CHN)
Whether you're in Europe, North America, Japan, across Canada, Central America, or China - once the watch is set to the local time zone, it picks up the corresponding radio signal and always displays the exact date and time. In many countries, it automatically switches between daylight saving time and standard time.

World Time Function
The world time function displays the current time across 29 time zones and major cities worldwide.

The Movement

At the heart of this sports watch beats a quartz movement. Accurate and built to last, it gives you access to both analog and digital time display at a glance.

The Strap

For a comfortable and stylish look, Casio chose synthetic resin for this strap. A beautiful khaki green color brings a trendy, refined edge to the design. A silver-tone pin buckle makes it easy to secure the strap around your wrist.

Water Resistance

With 100-meter water resistance - 10 ATM in the language of watchmaking - this bold timepiece is equally at home at a black-tie event and in the water. Feel free to keep it on in the shower, the bath, or during your swim sessions (even the intense ones). That said, our watch experts want to be clear: this model is not designed for scuba diving, freediving, or use with high-pressure water equipment. The rule is simple: shower, bath, and swimming only - and never operate the pushers or crown while submerged.
