Design & Material Analysis

Watch like a Casio pro trek PRW is quite different in its overall looks, functions, and appearance. Physically, this watch is 1.97 – 1.97 inches and is very light to carry. It’s only up to 5.92 ounces which is not an enormous weight.

The wrist and case size is also appropriate and matched to the watch face. The case of this watch is 5.6 c.m, and the thickness is around 15 mm.

For material, here you find different variations for both case and bezel. The case material of this wristwatch is made with resin or stainless steel.

  • Case and strap material durable, solid, that lasts up to one year or more
  • The display is easy to observe for perfect size and LED illumination

Solar Powered Battery Life & Trouble-free Charging Capabilities

This watch is a solid material of solar series watches because it will allow you to charge by connecting with the sun. We like the integrated solar panel system used here to catch the sunlight and UV light to recharge the watch’s battery.

For this, a user won’t need to carry a charging cable to charge the watch every 2-3 days. You won’t need to delay your time by setting this watch during an emergency.

Pro Trek Version 3 Triple Sensor & Multi-functional Activity Tracking

This watch has an advantageous sensor named pro trek version 3. Correspondingly, this combines altimeter, thermometer, and digital compasses.

Besides this, the V3 compass is also very accurate compared to other multisport watches’ GPS readings. In fact, this is precise in this function.

Again, this watch also has an altitude feature necessary for adventure mountaineers and mariners. It’s because they provide exact data about what those people expected.

The altimeter can track the height from the sea or give you the minimum hints of how long you’ve climbed over the mountains. So this watch is a great relief for those who love to travel and for the mariners, sailors, and climbers.

Again, this watch barometer function gives you both a reading of barometric pressure and a graphic that tracks the timing while climbing over something.

In addition, the tracking graphic of these timepieces is excellent for quickly checking the weather trends. The temperature reading is accurate within 10 degrees.

+/-11 Accurate Degrees Compass Function

As insisted by its reviewers, the compass function of Casio pro-PRW3500T-7 is only accurate to +/-11 degrees. But sometimes, it varies while this watch is tested against a military-grade lensatic compass.

In a military-grade lensatic compass, this timer display showed azimuth directions quite different from lensatic compasses. Overall, this watch would be helpful as a backup compass to trace general rules.

1/10 Stopwatch Measuring Range

Casio Pro trek is also suitable for having a 1/10 second stopwatch measuring scope. It’s an excellent feature for adventure junkies. Elapsed timing modes can measure step counter systems.

And it supports the split time, which is far better than the traditional watches. However, the 24 hours countdown start time setting range of this timer is fantastic due to the 1-day timing increments.

For this, one can easily measure their traveling or training time per day with less difficulty.

In shorter meaning, this watch has a 1-second countdown range up to 1 minute to 24 hours. And this timepiece follows a similar quality measuring amplitude to the digital clocks, for instance, 999:59’59.9″.

200 Meter Water Resistance

Casio pro trek is the top smartwatch for diving. Because it has water resistance up to 200 meters. And you know, 200-meter water resistance is worthy for those who are very professional and must attend heavy projects under the sea.

Using this hand timer, one can be submerged up to a maximum depth of 200 m. Yet the manufacturer claimed that this watch has more water depth, around 660 feet.

So if you’re a diver or used to swimming regularly, it is highly suggested to use this sensor-type watch, such as the Protrek 3500T-7CR.

It is now easy to trace 31 world time zones by this timer which is appreciated. So, you can check the time of any country, no matter whether you’re living in China, Sweden or Maldives.

Since it has an affinity to track 48 cities, one can also check out the city name on their watch display. It also allows you daylight saving on/off mode.
