Product Description:
The watch that started it all! Suunto's original Wristop Computer, the Vector changed the face of sport watches forever with its groundbreaking combination of features, including an altimeter, barometer, electronic compass, digital log book, and watch. Introduced in 1998, the Vector was the first watch to make it to the summit of Mt. Everest. Today, the Vector is still considered the standard by which other sport watches are judged, and it remains a favorite everywhere, from the mountain tops to the Marine Corps.

Amazon.com Product Description:
Designed for the mountaineering, outdoor traveller, this hardy wrist-mounted computer provides all the information you'll need for any adventure, including a digital altimeter, barometer, compass, thermometer, and a regular watch. It's backlit for easy viewing, and water resistant down to 100 feet below surface.

The altimeter includes functions showing current altitude up to 29,500 ft/9,000 m, and your ascent/descent rate in feet or meters per minute. Its difference measurement function allows zeroing of the altimeter for following your vertical progress between various destination stages, and the automatic 24-hour memory stores your altitude and ascent/descent rate for every hour continuously, with a logbook that stores total ascent/descent, average ascent/descent rate, and even the number of runs you've skied for the duration of the log.

The barometer provides absolute pressure range from 8.90 - 32.40 in Hg / 300 - 1100 mbar, and sea level pressure range 27.25 - 31.90 inHg / 921-1080 mbar. You'll also get 0.05 inHg / 1 mbar resolution, and a difference measurement function that allows zeroing of the barometer for following overnight changes in barometric pressure and temperature. There's also an automatic 4-day memory--which can store pressure information in one hour intervals for the last six hours, then in six hour intervals after that--and a handy, adjustable, sea-level pressure function.

The compass function includes bearing in degrees and cardinal or half-cardinal point, a North-South arrow, and a bearing tracking function which displays locked bearing, actual bearing, and the difference between these declination adjustments. There's also a bubble level to indicate level position to ensure +/- 2-3 degree reading accuracy, and a declination adjustment. The watch function provides a basic 12/24 hour clock, a calendar pre-programmed to 2089, 3 daily alarms, and a stopwatch and countdown timer that both run for 23:59:59 hours. You'll also get a thermometer, and the watch comes with a user-replacable battery. All this is packed into a 1.9 oz. device.

Rating : - Perfect for the rain forest
I just returned from spending two plus weeks in the rain forest in coastal British Columbia. This watch worked perfectly. It was critical to have the thermometer altimeter and the barometer. I was able to use topographical maps and the watch to know where I was on the mountain. I was also able to leave the rock face when the barometer predicted incoming rain. This piece of equipment (far more than a watch) was critical to the success of the expedition.Suunto Vector Wrist-Top Computer Watch with Altimeter, Barometer, Compass, and Thermometer
