Casio Pro Trek PRG-300CM—For what it costs and the superb durability you get from it, it is a no-brainer for a beginner and casual user.


  • + Cheap
  • + No maintenance required (04 years so far)
  • + Durability (Water resistant)
  • + Solar Powered
  • + Functions (backlight, chrono, timer, dual time zones, compass, altimeter, barometer, thermometer)


  • - Crystal is not scratch resistant (although the bezel is thick enough).
  • - Wristband could not be too pretty.
  • - Could have at least a couple more functions and memory.

First of all, I am not a professional trail runner nor an avid trekking or hiking goer. Overall I am an outdoor enthusiast and that has from time to time the chance to go to the beach, mountains, or project sites. For all these duties, and more, this watch is more than capable.

In a world where the summit is for the SUUNTOs and TISSOT T-Time (in terms of technology and durability), these cheap and readily available, but overall, durable, CASIOs are more than enough to complete your gear list.

First of all, is SOLAR powered, so that means will work tirelessly to the end of times... well, maybe not that long, but at least, years before you need to change the battery.

Second is precision and readability, a black screen with white or clear fonts. Some function icons are too small, but you can live with that. Did I mention the backlight?

Third, there is plenty of functions, that could be maybe another three more, however, is more than enough for starters.

This is a model where CASIO engineers have reduced the size of the tri-module (Altimeter/Barometer, Thermometer, Compass) making them smaller than GShocks and the PRG-3000 series.

Is a mid size, light and not that bulky watch (there is even a womens' version) that deserves a try.



I have had it for four years so far. Have used almost everyday 7x24x52 and no complaints. Have traveled with it (nationally and abroad), gone to the beach and pools, no regrets.
