A monitor device to be worn by a diver and characterized as automatically providing and maintaining information in display form of the submerged time and elapsed surface interval time, comprising: (a) switch means; (b) means for activating said switch means (a) at a predetermined depth; (c) means for accumulating and displaying submerged time; (d) means for accumulating and displaying surface interval time; (e) means for resetting submerged time (c) and surface interval time (d) displays to zero; (f) means for stopping accumulation but maintaining display in said submerged time means (c) while starting accumulation and display in said surface interval time means (d) when the diver rises above said predetermined depth; (g) means for maintaining the accumulation and display of the surface interval time (d) until the diver descends again to said predetermined depth; and (h) means for preventing actuation of said resetting means (e) until there has been a minimum predetermined surface interval time.
