Audio alerts by watch pagers use a lot of power and in certain circumstances may not be heard by the user. An alternate approach to an audio alert is the use of water. Water is released to the wrist of the wearer in place of an alert. A pump pumps water from a reservoir for an alert. The reservoir may also serve as battery electrolite if the battery type is equivalent to that of the "Water Watch", The wrist worn device may comprise either a watch, a pager or a com- bination watch and pager, and the alert may be in response to either a page or a time of day alarm. This method of alerting has the additional advantage of generating an alert with potentially less battery energy than the current method of generating an audio alert or a vibrating alert, This is true because the sensation of the alert is generated by the sensation of cool water which is the result of evaporation. The evaporation is a natural process and does not require battery energy as does audio and vibrating alerts.
