Got myself a Casio Triple Sensor over in the States a couple of years ago for about £80. Changed the strap straight away to an Animal velcro one, I too have weedy wrists and it looks a bit chunky. One problem with thermometer watches is they pick up body heat and can give a false reading. Solution - the velcro wrist strap slides through the webbing of my rucsack shoulder strap, fastening the watch at a convenient place to view it. It's 100m waterproof so can take a drenching, but the compass starts to deviate if the watch isn't held true horizontal. Has altimeter, stopwatch, alarms and plots a graph of the days walk.
