Casio's Pro Trek PRJ-B001EX-1JR left preorder on August 7 and is now available to buy in Japan at ¥33,000 (~$208). 51 grams, 10-bar WR, Tough Solar, Bluetooth position sync. A strap that unzips into a coin pouch struck some Pro Trek owners as a gimmick instead of a hiking instrument. Tough Solar handles power; Bluetooth logs position and time to a map in Casio's app. Buy the Casio Pro Trek PRJ-B001B-2 on Amazon.
