I have had the Pulsar Watch for about a year and like it, although the stop-watch is a bit small to use in flight. Ocassionally it stops for a few hours and re-starts all by itself, when it does that I revert to my Vostok Amphibian:
Vostok Amphibian: Vostok Amphibian Automatic AM 420634 @ www.sovietwatches.co.uk
31 jewel automatic movement, designed to survive EMF pulse of a Nucleur blast...even if your arm isn't
