That's pretty cool.
I was climbing (walking) Mt Oberon in Wilsons Prom the other week, and this kitted out Swiss guy in fancy trekking gear and walking poles came walking back down the mountain. My girlfriend, Lisa, asked him how much further to the top. He looked at his watch and said 150m. We were surprised and said "oh, is that all!", and he said, "oh that's up, not in walking distance." I later commented to Lisa that it's probably the first time he's had a legitimate use for that watch
