The new PRW-6600Y-2 features Triple sensor technology (altimeter, barometer and Compass), Multiband 6 Atomic time keeping and is equipped with Tough Solar charging. This watch is one of the most desirable timepieces in the Pro Trek line. The PRW-6600Y-2 uses Casio’s advanced SMART ACCESS system, which provides you with quick, intuitive access to all of the watch’s key functions using an electronic crown.

Atomic Timekeeping
Shows accurate time by receiving radio signals of standard time information. JJY= Corresponds to both of Japanese standard waves JJY (40kHZ/60kHZ); WWVB= Corresponds to the USA standard wave WWVB (60kHz); MSF/DCF77= Corresponds to UK and Germany standard waves MSF/DCF77(60kHz/77.5kHz); BPC= Corresponds to Chinese standard wave BPC (68.5kHz)
-
Solar Power
A solar cell provides power for operation
-
Compass
A built-in direction sensor detects magnetic north
-
Altitude Measurement
A built-in pressure sensor measures barometric pressure, which is converted to relative altitude
-
Barometric Pressure Measurement
A built-in pressure sensor measures barometric pressure, which is shown on the display
-
Temperature Measurement
A built-in temperature sensor measures the temperature
-
Auto-Hand Location
Using an LED, the positions of the hour, minute and second hands are checked at the 55'00" of every hour to ensure correct hand positioning. If the hand time does not coincide with the counter within the IC, the movement corrects the hand position automatically
-
Low Temperature Resistant -10°C/14°F or -20°C/-4°F (-10°C/14°F)
The timekeeping module is designed for operation at very low temperatures. The value indicates the lowest temperature at which the module will operate. *-10°C/14°F or -20°C/-4°F do not apply to the direction sensor
-
LED Light (Full Auto Double Illuminator)
Separate lighting for the digital and analog portions of the face for easy reading. Illumination is automatically disabled when surrounding light is sufficient and enabled under dim or dark conditions
-
World Time (R29)
Displays the current time in major cities and specific areas around the world. R: Current time in major cities around the world. Values indicate number of cities/areas
-
Daily Alarm, Hourly Time Signal (5)
The daily alarm sounds each day at the time you set. The value indicates how many alarms are available. The hourly time signal causes the watch to beep every hour on the hour
-
Stopwatch (1/100 24HR)
Accurate measurement of elapsed time with the touch of a button. The fraction indicates the unit of measurement, while the time figure indicates the maximum time measurement
-
Timer (60 MIN)
Counts down from a start time specified by you. The value indicates the number of timers available, while the time figure indicates the maximum starting time. “REPEAT” indicates Auto Repeat, which automatically restarts timing at the end of each countdown
-
Full Auto-Calendar
Allowances are made automatically for months of different lengths, including leap year
-
12/24-Hour Timekeeping
Times can be displayed in either 12-hour or 24-hour format
-
Operation Tone On/Off
The tone that sounds to signal a mode change or other operation can be turned on and off
-
Battery Level Indicator
Indicator shows the current battery level
-
Water Resistant (10 BAR)
The “BAR” value indicates the number of atmospheres to which water resistance is ensured. 20 BAR means water resistance to 20 atmospheres. Watches marked “200m” have the same water resistance as 20 BAR watches
-
Neobrite
A luminous coating provides long-term illumination in the dark after only short exposure to light
-
Mineral Glass
Hard glass resists scratching
-
Crown
Screw-Lock
