I work in a field that requires me to shoot things while climbing mountains, and I’m telling you that thing survived all sorts of things thanks to the extra durability of the surrounding plastic. Also I’ve removed the watch from its housing and the entire watch extends into the inside of that plastic housing due to the ABC sensors and atomic clock radio modem to sync time automatically.
Also the entire watch face is not a slit, and acts as a solar recharge panel. So that extra bulk is actually functional, unlike your obese fat ass.
