Description

The case, case back, and soft urethane band are all made with a material known as biomass plastics. Using renewable organic resources such as castor oil plants and corn helps reduce the footprint.

Measure direction, air pressure and temperature, and altitude, each one available directly from a single button. The oversized buttons feature a nonslip finish for effortless use even when wearing gloves. In addition, improved sensor placement makes the side of the case even slimmer. Approx. Battery operating time: 7 months on rechargeable battery (operation period with normal use without exposure to light after charge) 27 months on rechargeable battery (operation period when stored in total darkness with the power save function on after full charge) Integrated Solar Panel That Uses Sunlight and UV Light to Recharge the Watch’s Battery Triple Sensor (digital compass, barometer/altimeter, and thermometer) senses natural changes The case, case back, and soft urethane band are all made with a material known as biomass plastics.

  • Best work/outdoors watch.
Color: Silver Style: PRG-340T-7CR
Perfect everyday watch! This is my second one, I hand the last one for 12 years countless deployments and travel. Held up great. very durable and reliable watch. Great value when you get it in sale. Size fits just right in my wrist which is about average size.

  • Very Accurate
Color: Silver Style: PRG-340T-7CR
I bought the titanium band version as I prefer metal bands when available for longer life and greater comfort in high summer temperatures. They are subject to scratching but as a retiree I am easy on watches. My sample remains within 1 second of my atomic clock after 2+ weeks of wear so excellent accuracy. No real need for Multi Band 6 radio synchronization with this accuracy level though I do have watches with that feature. The triple sensor provides more features than I need and I like the sunrise/sunset calculation capability. Solar charging is also great. Overall a excellent light weight outdoors man's watch. Currently, and when I bought it, the Titanium band version is a best buy as Amazon has it for the same price as the resin band versions. Per the listed MSRP the titanium band version is normally a $50 cost premium. To me the titanium band version is a much dressier looking watch and titanium does not wear out like resin bands do. ... show more

  • Very durable, No charging
Color: Silver Style: PRG-340T-7CR
Had a very similiar protrek 15 years ago for 10 years. I switched to a smart watch and couldnt bear the constant charging. Now i return to protrek and feels like home.

  • Cheap band!
Color: Silver Style: PRG-340T-7CR
Works the same as an old Suunto I have. Very light, feels good on wrist. The only downside is the metal band. It is not secure, comes off if your cuff catches the release buttons. I replaced it with a better band and that solved it.
