ABSTRACT:
A depth measuring device suitable for use in a dive watch is provided. A water depth measuring device comprising a pressure sensor, an A/D converter that converts the sensed signal of the pressure sensor into a digital value, the digital value corresponding to the start of water depth measuring being the initial digital value, a comparator that compares the initial digital value output by the A/D converter with a range of values defined by a first predetermined comparative value and a second predetermined comparative value, and determines whether the initial digital value falls within the range and produces a comparison result based thereon, an initial value setting circuit that, in response to the comparison result of the comparator, adopts the first digital value as an initial value corresponding to a zero meter depth when the initial digital value falls within the range defined by the first and second comparative values, and a water depth computer that computes a water depth value based on the initial value and the digital value derived from the A/D converter.
