This Citizen Eco-Drive Promaster diving BJ2010-56E watch is an analog solar powered diver’s watch into which an electronic depth meter function and chronograph function are built. The solar power generation function transforms solar energy to electrical energy to run the watch.  Since solar energy is used as the power source of this watch, it has no need of regular replacement of the battery unlike the general diver’s watches using the mercury cell, etc. The built-in depth meter function automatically measures the depth in diving with the watch worn on the wrist. The maximum depth in diving is automatically memorized by maximum depth memorizing function of this watch.  The chronograph function measures the time in units of one second for 50 minutes at maximum. A secondary battery is used in this watch to store the electrical energy. This watch has an overcharge prevention function. When the secondary battery is fully charged, this function is activated to protect the battery from overcharge by cutting of power supply. This function relieves you from worry about overcharge.

The chronograph function enables this watch to measure time in units of 1 second for a maximum of 49 minutes 59 seconds. When it has reached 50 minutes, since a time measurement was started, the chronograph stops measuring time and the hands move to the reset position. The luminous paint used for the dial of this watch is mainly made from light accumulating materials, which are harmless to the human body and the environment since it contains no toxic substances such as radioactive material. This luminous paint accumulates light of the sun and indoor lighting and emits light in a dark place. This Citizen Promaster watch is water-resistant against water pressure at the depth of 200 m. The crown of this watch is designed to be screwed down to secure the water-resistance of the watch. This watch indicates a depth based on the specific gravity (1.025) of seawater. This watch has an another interesting overzone mark feature. When the diving depth exceeds 50 m (125 ft) or there is something abnormal in the depth meter function, the function hand points to the over-zone mark.
