The top travel ProTrek series with a cult triple sensor [barometer, thermometer and compass] and ana-DJ display. Ion-plated steel bezel – now you don’t have to worry about scratches and scuffs. Codes of cities are marked on the bezel – for the function of world time. Yes, the dial is nothing superfluous – arrows, a small window for indicating modes and a large informative electronic window, in which all the necessary information is concentrated. Smart Access crown for quick access to watch features and Tough Movement hands are elite features for dial hands. The PRW-6600 has a solar battery, which is charged from daylight, and the time is synchronized by radio signal. The fastening of the strap implies its quick replacement with another, depending on the situation [urban style or outdor].

The most distinctive specs of PRW-6600 *Editorial
— 100-meter water resistance (good for swimming but not for deep diving)
— Tough Solar (CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power)
— Radio-controlled Watch; Multi band 6 (additional way for time sync. This watch receives time calibration radio signals that keep the displayed time accurate)
— Low temperature resistant (stable operation of the watch is guaranteed even at a temperature of -20°C)
— Digital compass (measures and displays direction as one of 16 points)
— Thermometer (can measure and display the outside temperature in a range from -10 C to 60 C)
— Barometer (measures the air pressures and displays tendencies in the weather)
— Altimeter (The electronic mechanism “estimates” the altitude based on the air pressure)
— Height Gain (The height gain sums all the meters you have climbed in a session, so that you can see at a glance the total ascent on a tour)
— Smart Access (the system for analogue movements achieves multi-functionality and easy operability simultaneously through a combination of multiple motors and an electronic crown)

Official PRW-6600 Specs / Features *for base version PRW-6600Y-1
- Full-Auto LED light
A twist of the wrist in weak light conditions automatically lights up the display backlight. - Low-temperature resistant (-10 °C)
Even temperatures as low as -10 °C have no effect on this watch. - Solar Power
A solar cell provides power for operation. - Radio signal reception (EU, USA, Japan, China)
Whether in Europe, North America and Japan or in the outer reaches of Canada, Central America and China – once the watch has been set to the local time, it receives the relevant signal and shows the correct time wherever you are. In many countries, it also sets itself automatically to summer and winter time. - Neo-display
A luminous coating provides long-term illumination in the dark after only a short exposure to light. - Barometer (260 / 1.100 hPa)
A special sensor measures the air pressure (measuring range: 260 / 1100 hPa) and presents this on the display in the form of a symbol. This enables early detection of weather trends. - Thermometer (-10°C / +60°C)
A sensor measures the ambient temperature around the watch and displays it in °C (-10°C /+60°C). - Digital-compass
A built-in direction sensor detecs the magnetic north. - 10,000 m Altimeter
A pressure sensor detects changes in the air pressure and converts the result into an altitude up to 10,000 m. - Height Gain
The height gain sums all the meters you have climbed in a session, so that you can see at a glance the total ascent on a tour. - Altimeter data memory
Depending on the model, up to 40 sets of elevation data can be stored in the watch’s data memory and re-accessed at any time. Each of these data sets consists of a measured altitude as well as the date and time. In addition to the individual altitudes, the maximum and minimum altitudes during a measurement are also stored. - World time function
Displays the current time in major cities and specific areas around the world. - Stopwatch function – 1/100 sec. – 24 hours
Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 24 hours. - Timer – 1/1 min. – 1 hour
For fans of precision: the countdown timers help you to remember specific or recurring events by giving off an audible signal at a preset time. The time can be set to the nearest minute and up to 1 hour in advance. - 5 daily alarms
The daily alarm reminds you about recurring events with an acoustic signal at the time you have set. This model has 5 independent alarms for flexible reminders of important appointments. - Automatic hand adjustment
The automatic hand adjustment function checks the home position of the hands every hour and corrects it if necessary — either by adjusting e.g. from shocks or using the influence of magnetism. - Button tones on/off
The button tones for using the mode button can be turned off. This means that the watch no longer beeps when switching from one function to another. Preset alarm or countdown timers remain active when the button tones are deactivated. - Hand Moving Function
With a push of a button, hands are moving and permit a free visibility of functions like stopwatch or date. - Crown button lock
Secures the crown button from accidental change to another mode of operation. - Smart Access Technology
Smart Access makes it easy to operate multi-function watches. Simply pulling out and rotating the crown provides intuitive control over all functions - Automatic calendar with Date, Day and Month
Once set, the automatic calendar always displays the correct date. - 12/24-hour timekeeping
Times can be displayed in either a 12-hour or 24-hour format. - Mineral glass
The tough mineral glass resists scratching. - Resin case
- Bezel with IP Finish
The bezel of the watch is elaborately coated according to the so-called “ion plating” process and offers the advantage of increased scratch resistance - Resin band
Synthetic resin is the ideal material for wrist straps thanks to its extremely durable and flexible properties. - Buckle
- Battery level indicator
An indicator shows the current battery level. - Water resistance classification (10 bar)
Perfect for swimming and snorkelling: the watch is water resistant to 10 bar according to ISO 22810. - Dimensions (H x W x D)
51,6mm x 51,5mm x 13,6mm - Weight
