Casio is one of the most recognized watch brands in the world, delivering timepieces packed with innovative features and advanced technology. Known for their rugged, powerful designs, the G-Shock models are in a class of their own - and the DW-H5600-1ER is proof. This standout watch comes with an octagonal case made of durable resin that takes the hits so you don't have to. It measures 44.5 mm wide, 51.1 mm long, and 17.4 mm thick, with an average weight of just 59 grams - impressively light for its size. The case houses a mineral crystal covering the dial, with push buttons on both sides for controlling all functions. The case back delivers a water resistance of 20 ATM.
Sleek and modern, the dial of this watch delivers a clean digital display. Against a black background, the screen clearly shows hours, minutes, seconds, date, day, and alarm status, along with all the feature indicators that define this timepiece. The Full Auto LED backlight ensures optimal visibility in low-light conditions. The brand name and movement type appear at the top of the dial, while "Bluetooth" and the water resistance rating are noted at the bottom.
Bluetooth® Smart
The watch features energy-efficient Bluetooth® technology that allows data exchange with the press of a button. The Bluetooth® function wirelessly connects the watch to a smartphone, unlocking a wide range of highly practical features.
Smartphone Time
When the wall clock is paired with a smartphone, the time is set automatically and displays the current local time anywhere in the world.
Full Auto LED Backlight
Tilting your wrist in low-light conditions automatically illuminates the dial via an LED.
Shock Resistance
The shock-resistant structure protects the watch against impacts and vibrations.
Solar Power
Solar cells provide autonomous, eco-friendly power. Any surplus solar energy is stored in a rechargeable battery.
Calories Burned Calculator (CAL)
This function calculates calories burned and saves the result.
Heart Rate Target Alarm
An alarm sounds as soon as a pre-set heart rate zone has been reached.
Optical Heart Rate Measurement
An optical sensor on the back of the watch uses LEDs to measure heart rate at the wrist. The values are displayed on the wall clock.
Accelerometer
The accelerometer responds to acceleration and displays speed on screen. It is also essential to the watch's auto-rotation function, ensuring the display always shows the image the right way up.
Step Counter
The watch measures the number of steps taken.
Training Planner
Set Individual Training Goals
Training Analysis
Analyzes training status, fitness level, training load, and recovery time.
Training Log
A training log records step count, calorie burn, distance, and lap times - making it easy to compare training sessions.
VO2max
The VO2max value is a key indicator of aerobic fitness and reflects an individual's personal performance level. A lower VO2max signals poorer physical condition, while a higher VO2max indicates a higher performance level. Regular training can improve your VO2max over time.
VO2max Recovery Time
Good training demands good recovery. To make every session as effective as possible, the VO2max recovery time display tells you exactly how long your body needs to bounce back from your last workout - so you know precisely when you're ready for the next one.
Activity App
The watch offers multiple training modes that can be pre-set to individually assess and track the corresponding activity. In Swimming mode, for example, the focus is on calorie burn and distance, while in Running mode, heart rate and speed are displayed in detail.
World Time Function
The world time function displays the time across 29 time zones and major cities around the world.
Stopwatch Function - 1/100 sec - 100 h
1-second precision timing: elapsed time, split time, and final time. Audible signals confirm start and stop. Timing capacity reaches up to 100 hours.
100-Lap Memory
This memory stores dated chronograph readings, lap times, and split times for later review. Each data block contains the following information: date, elapsed time, lap time, and split times. The memory can hold up to 100 such data blocks.
5 Countdown Timers - 1/1 sec - 60 minutes (with Auto-Repeat)
This model features five independent countdown timers that emit a signal when the set time expires, then automatically restart from the pre-programmed time. Measurement capacity reaches up to 60 minutes and can be set in 1-second increments.
4 Daily Alarms
A audible alarm reminds you of your daily deadlines at the programmed time. This model features four independent alarms to flexibly keep you on top of your most important appointments.
Snooze Function
Every time you stop the alarm, it goes off again a few minutes later.
Vibration Alarm
The vibration alarm discreetly reminds you of your important appointments without any noisy signal.
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 countdown timers remain active after the button beep is turned off.
Find My Phone Function
Lost your smartphone? Just press a button on your watch and your phone will sound an alarm.
Auto Calendar
Once set, the auto calendar always displays the correct date.
12/24-Hour Time Format
You can display the time in 12-hour or 24-hour format.
This model is powered by a Japanese-made solar movement. Solar cells provide autonomous, eco-friendly energy, and a rechargeable battery stores any surplus power. Reliable and precise, it efficiently drives all the watch's functions. Note that it can also be charged via a USB charger.
This watch features a rugged strap crafted in durable resin. In black, it's ideal for physical activity and is secured with a pin buckle that keeps it firmly in place around your wrist.
With a water resistance of 20 atmospheres, equivalent to 200 meters, this model is what you'd confidently call a dive watch. Our watchmaking experts agree: while this timepiece handles showers, baths, lap swimming, freediving, and recreational scuba with ease, it is not designed for extreme deep-sea diving, where pressure would exceed its water resistance rating. For our professional diver friends looking to push depth limits, we recommend exploring 30-atmosphere models and above. We also strongly advise against operating the push buttons or crown while in the water - to keep that seal perfect!
