Headquartered in Vantaa, Finland, Suunto manufactures sport watches, specialty diving equipment and compasses. The company started in 1933 with revolutionary compass making. It was a short leap into watches from there. The company is famed for their multi-function watches that have a variety of functions including, not surprisingly, a compass, altitude meters and GPS location. The M-series is designed for fitness with heart monitors and electronic coaching. The Ambit line is the most advanced and includes GPS, altitude, barometer, compass and smartphone connectivity with downloadable or customizable aps. The Suunto Lumi is designed for women and comes with an adaptor than can be worn as a pendent.
