Every watch has an intended purpose (in theory). I thought this might be a good opportunity to see everyones photos of their watches in the environment to which it is best suited. Here's the PO just off Huka Falls on the Waikato River here in Taupo, New Zealand - alongside a couple of quick photos. Not in the ocean (its pretty cold), but close enough :). The timing bezel currently being used to indicate Sydney time.
Whether you've snapped your Explorer up Everest or your Speedy on the moon - lets see them!
