## Description

Get out into the great outdoors with a solar-powered PRO TREK featuring eco-friendly materials that care for the environment. The PRO TREK line of authentic outdoor gear for nature lovers introduces the PRG340, a timepiece that incorporates environmentally friendly biomass plastics* while delivering the same comfortable fit for your wrist. The PRG340T case is crafted from biomass plastics made with castor oil and the band is made of titanium. The duplex LCD lays out separate layers for the compass graphics and the clock functions, enabling a larger compass display for better legibility and easier navigation in a design that is both functional and beautiful. The rotating bezel makes it simple to record compass readings, and the Tough Solar charging system keeps the advanced functionality on the go. Get out and explore with a gentler footprint! * Biomass plastics are polymers produced using chemical or biological synthesis of materials sourced from plant matter or other renewable organic substances and are widely thought to help reduce environmental impact and promote the shift to a circular economy.

Review: 10/10 - Having had a previous protrek watch for 12 years, I decided it was time for upgrade. This watch was my choice as they are very robust and very accurate time pieces. All the bells and whistles appeal to me and I use them all on a regular basis. This particular model was retailing between £280 and £365 on various internet sites. This one was £207 from desertcart US and that included the import duties. A no brainer and it took only a week to arrive, The watch is beautifull and light on the wrist. I have ran through all the features and it performs flawlessly. The titanium strap is long enough for a large wrist, and I had to remove 3 links for my perfect fit, but the added tool made this an absolute breeze. All in all I give the watch, price and delivery 10/10 and am over the moon with my purchase. It will not dissapoint.
Review: Solid performer and no batteries to worry about - Certainly the best Casio that I have ever owned ✅
