After the advanced GBA-800-9AER [where synchronization with the phone works functional wonders], I wanted to return to something “tube-like” and so familiar from the Japanese manufacturer. I did not have to choose for a long time, because in our collection of author’s reviews a rather new model PRW-6600YB-3ER was lost, which is definitely not inferior in function, and it was created for “tube” fans of travel gadgets.
I would call representatives of the PRW-6600s one of the best ProTreks today. I agree, it sounds very bold, but in the review I will try to explain such loud statements.
Let’s start with the traditional tourist opportunities that the Japanese have been “honing” for years: the triple sensor 3 versions will please with accurate indicators of the altimeter / barometer, compass and temperature. If someone argues in the style of “they show incorrect data”, then you are simply unfamiliar with the calibration [data correction for accurate indicators of another perfect source]. It all depends on you, namely, how much you want to use the watch in practical terms. “This is uncomfortable!” – a voice is heard in the comments. As it were, synchronization with the phone or other nice smartwatch chips can reduce setup time, but with one very powerful minus – poor autonomy. Unfortunately, any smartwatch so far needs constant recharge from power sources, and this no longer fits the philosophy of true hiking fans, where every extra gram of extra weight can put you out of order.
PRW-6600YB-3ER is powered by itself from any light [the watch has Tough Solar technology] and can work in the dark for as long as 25 months [without any lighting]. If you imagine any tourist activity, it cannot be without daylight [in 90% of cases], which means that the clock will always be in operation. Check and check Suunto, AppleWatch, etc. for everyone there. Of course, it is unfair to compare with other representatives who have gluttonous GPS capabilities, but even without determining the location, few can work so confidently for a long period of time. Let’s not forget that the PRW-6600 is designed for fans of classic tourism, where GPS is not needed [there is a compass and a map that will always point in the right direction].
Radio synchronization is responsible for the accuracy of the current time. “Oh, it doesn’t work in our open spaces” – it may not work only in very remote places from the European tower [and in very rare cases]. Judging by the reviews from various forums, the countries of central Europe [including the CIS] are very well synchronized. In Ukraine, Belarus and even Russia, for example, it may not “catch” one day, but on the second, third or tenth everything is ok. Even a correction once a month will be enough for you to have amazing accuracy on your wrist.
Tough Movement technology [in addition to the previously described features] also includes a hybrid case structure [a mixture of a polymer material with metal components] for more durable watch features and hourly correction of hands. That is, every hour the analog block checks the correct operation of the hands in relation to digital time and corrects defects if necessary. Isn’t that perfect?
Something brought me into the description of key technologies, but it is no coincidence, friends, because the PRW-6600 differentiates this from very similar PRG-600 and PRG-650. They essentially gathered all the best from the “PRG” indices and now they are only happy with their new position.
Let’s move on to the look of the PRW-6600YB-3ER, where you can also see a lot of visual improvements. At least I was surprised by the presence of Arabic indices at all time stamps [which cannot be said about “PRG. In this way, the manufacturer is trying to improve the readability of analog information and it certainly did [including thanks to the wide 51.6 × 51.5 × 13.6 mm case, which in principle has not changed compared to the PRG-650].
don’t know if you can see it, but the 6-hour figure “stuck” to the mineral glass, while the other marks are much deeper. This creates an atmosphere of depth of the dial. Large hands, large hour markers – everything was created for the image of the classic “hands”, but we all understand that everything is not so simple. Therefore, yes, the clock can also be used for office professions, which are definitely not against weekend activities.
I can not help but pay attention to the metal, ionized bezel. This is not the same shabby format as in the PRW-3000 – should surely serve for years. The city codes are “driven” into the bezel, so do not worry about their disappearance over time.
The functional part of the review will not be much described, since most of the functions work in the traditional electronic [for Casio] format [thanks to the electronic window]. The only thing that really interested me was the capabilities of the Smart Access crown. I would like to know how exactly it “simplifies” the life of the owners of the PRW-6600.
Quick time zone selection
As soon as you scroll and pull out the crown [in the current time mode], you will immediately find yourself in the time zone selection for display. The rotation of the head rotates the second hand by dividing the city codes around the bezel, where you just have to stop at the desired one and press the head back [thus activating the desired city]. Really very comfortable.
Fast sensor calibration
Activating the crown in barometer / thermometer / altimeter mode allows you to calibrate indicators: turning left / right changes the current numbers. You just have to set more accurate indicators. In principle, this is very easy to do.
Quick timer setting
In the stopwatch mode, smart functions do not work, but you can set the countdown timer in several rotations.
You can read about Smart Access in a separate article on the blog: Smart Access in Casio watches – the convenience of setting up functions.
Strap. The PRW-6600YB-3ER watch has personally pleased me with a cult fabric strap.
Well, he is very dense, with many seams that will not allow him to go into all seriousness. The width of the strap is sometimes striking [as much as 2.4-2.5 cm], although for a tourist look it is very approx.
I draw your attention to the convenience of replacement – Casio persistently saturate the latest models with additional “levers” for instant removal of the strap.
Perhaps this is due to the aggressiveness of the promise environment, where the strap, as a rule, acts as a weak link, and therefore needs to be quickly replaced. I already thought it was a sinful thing to do business with straps, but no. There is no abundance of different stylistic solutions on the market, which means that this story is still local [so far there are two options: silicone and fabric]. In any case, such a convenience can not but rejoice.
“Specifications of PRW-6600”]
- 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.
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).
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

- Dimensions (H x W x D)
51,6mm x 51,5mm x 13,6mm
approx. 80 g
Backlight. Another pride of the PRW-6600 series, because not all models can boast the beauty of the Neon Illuminator and separate LED lighting of the electronic window.
Neon Illuminator is a technology where only the hands and hour markers are lit. No general illumination, you see only the necessary marks also in different colors. It looks amazing.
The electronic window is also illuminated at an excellent level.
The PRW-6600YB-3ER does not let go: it is very nice looking, functional inside, with a durable strap and beautiful backlight. Despite the lack of smart features a la mail check, the watch remains true to real tourism. Without pathos, without show-offs – only your mind, strength, map, necessary things and PRW-6600.
