With multiple functions including a tide tracker, temperature sensor and electronic compass all driven by a dedicated fourth hand the Timex Tide-Temp-Compass is the ultimate accessory for the tech savvy professional with a love for adventure. For tide clock, indicator hand always rotates clockwise, so tide is rising when hand is pointing left and falling when pointing right. Number of hours to next high/low tide is shown on tide scale. The primary factor in determining tides is moon position. Tide clock uses moon position to predict high and low tides, which are 6 hours and 12.5 minutes apart. Tides are also influenced by sun position and shape of shoreline, so tide clock cannot precisely give times of high and low tides. Periodic adjustment may be necessary. To set tide clock, pull crown to MIDDLE position. Press either TIDE or TEMP push button to move hand to current tide. TIDE and TEMP push buttons move hand clockwise and counterclockwise, respectively. Push crown in when done.
