Start by choosing your activity, then compare the exact reference’s sensor set, size, solar charging, and water resistance.
Quick answer
- Best for straightforward hiking: PRW-35 style models with core outdoor functions in a practical digital format.

What matters most when choosing a PRO TREK
For hiking and camping, confirm that the exact model includes the tools you will use: compass, barometer, altimeter, thermometer, sunrise/sunset data, or a dedicated activity function. Do not buy based on a family name alone—features vary by model. Also consider the case height and strap comfort, because a large outdoor watch is less useful if you leave it at home.

PRO TREK vs G-SHOCK
Choose PRO TREK when outdoor data and navigation-oriented functions are the priority. Choose G-SHOCK when impact resistance, street-ready styling, and a broad choice of everyday watches matter more. For solar G-SHOCK options, see our Tough Solar G-SHOCK comparison.
Final recommendation
For most hikers, the best PRO TREK is the one with the sensors you will actually use and a case you will wear all day. Start with PRW-35 for simple outdoor utility, compare PRW-61 for everyday versatility, and consider PRT-B70 when Bluetooth integration is genuinely useful.
