•the strap or bracelet is securely fastened to the watch case.

•the buckle keeps the strap or bracelet firmly secured to the wrist.

•the time and date are properly indicated.

•the small second hand is moving at one-second intervals.

•the log data of the previous two dives is recalled properly.

•all the hands for diving measurement are reset to “0” position.

While the small second hand is moving at two-second intervals, or when the DEPTH hand points to the 58-minute position after all the hands are reset to “0” position, the watch will not measure the depth. In these cases, replace the battery with a new one. (See “BATTERY LIFE INDICATOR”)
