I’ve not really found any good full histories of the casio pro trek range, so its seemed rip for the illuminating watches treatment. This video provides a relatively comprehensive view of early sensor watches, the first triple sensor with the ATC-1100 and DPX-500 and the whole pathway to today where we have quad sensor, smart watches with the WSD range and the much more compact triple sensor version 3 in the really coole PRW-30 range (I recently bought one with the STN-LCD display - its ace!). I try to pull out some of the mountaineers, climbers, kayakers and even astronauts that have worn Pro Treks, and alluded to a few cool film references (Robert DeNiro wears one - you’ll have to see the video to know the film…).

I’ve relied on some amazing resources to pull together this history with a particularly notable one being the Casio Fan Mag website as well as obviously the Casio Protrek website (including heavy use of web archive). I’ve looked to provide references throughout so let me know if any issues with images / video snips used and I’ll look to address.

Consider buying me a coffee if you really enjoyed the video: https://www.buymeacoffee.com/Illumina...
