Still soldiering after all these years: The Casio ProTrek PRG-510GB

I’m impressed that my ProTrek PRG-510 is still with me and in working conditions. I was not kind to it when I wore it for trekking, and I thought that it will stop recharging years ago. I can’t remember exactly when I bought it but I would not be surprised to find a pre-2010 invoice lurking inside its box that I kept somewhere in storage.

I stopped wearing it because for land navigation a mil compass worked better for me than the electronic compass of the PRG, and I never really used any of its other functions. The PRG-510 with its thick and wide case was also too huge to wear regularly. And so, the PRG-510GB is worn only occasionally and only on days when its US centric MMDD date format isn’t annoying me too much – like today.

It still works despite the dings and scratches to its PVD coating and the wear on its original black/orange funky strap. As far as I can determine, it’s still charging and keeping its power correctly and the second’s hand is still hitting all the markers correctly. I can’t see any scratches on the non AR coated mineral glass, despite the wear on the bezel that goes deeper than just wearing the PVD coating.

The main downsides? Too large, too thick, miserable lume, hilariously bad LED illumination, useless (for me) complications and an annoying MMDD date format.

Upsides? A credit to Casio/ProTrek ability to manufacture unkillable watches, very accurate movement, comfortable to wear despite its size and heft. I still like it despite not wearing it often.
