PRO TREK PRG-340 | April 2024

Biomass plastics used for most parts: A digital model with a duplex LCD

We’ve added a duplex LCD to our digital model with direct function buttons for one-push measurements. The rotating bezel, case, case back, and urethane band are made with plant-derived, renewable biomass plastics. Introducing this PRO TREK and celebrating its trailblazing progress in every direction: easy to use, easy to read, easy on the environment.

Digital compass now even more readable with the duplex LCD

The dual-layer LCD allows compass graphics to be shown on the top layer, while the bottom layer offers a large display of the time and various measurements. We’ve also made the LCD slimmer to minimise bulk, even with the dual-layer construction.

Earth-friendly craftsmanship with biomass plastics

The case, case back, and soft urethane band are all made with the Earth-friendly green material known as biomass plastics. Using renewable organic resources such as castor oil plants and corn helps reduce the ecological footprint. Eco-consciousness rendered in physical form, a fitting material for a real outdoor tool.

*Biomass plastics are not used in the metal band of the PRG-340T.

Direct function buttons for increased operability

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. The buttons are easier to press now, too.

Rotating bezel and movable lug construction

The bezel incorporates a rotating mechanism, allowing it to be used for simple orientation memory. The movable lug structure enables the watch case and band to be laid flat — handy when working with paper maps, checking where you are and where you’re going.
