The best inspiration is always found while searching the Timex archives. The Navi XL Automatic brings together design inspiration from their earliest diver-style watches and pairs it with a 21-jewel automatic movement…so your watch keeps ticking as long as you keep moving. Powered by your motion as you wear the watch, the movement can store a maximum 40 hours of energy. If motionless longer than 40 hours, wind the watch using the crown until you feel resistance, set it and place the watch back on your wrist where every motion will provide energy for the movement. The black stainless steel case with a uni-directional rotating top ring, black dial and black leather strap provide a modern take on this vintage design.
