I went to Rason City or Rajin-Sŏnbong in North Korea, on April 2012. Me and my team swam in the Sea of Japan, we had a Tissot watcht with digital termometer. We couldn't stand more than 20 seconds (IT WAS EXTREAMLY COLD) but we put the watch in the water and in less than 50 seconds it showed 8 degrees. But I would say that if we would have left the watch one minute more it would have showed 2 or 3 degrees.
