Perhaps a sports watch will help him to keep track of the time. I've began looking into all sorts of sports watches, including the TAG Heuer FORMULA 1, which I think really looks nice. It is not so bold looking but at the same time very sporty. This will just suit his personality. Having a watch will help him manage his time better and will help him to plan on his steps.
He could also use some gadgets that I think will be very helpful when he out. A GPS tracker to help him navigate his way in the mountains, a power bank to keep his smartphone running, and some backpacking gears.
