display the split time, lap time and total elapsed time or lap time in progress at the same time in separate rows. In addition, the stopwatch is water resistant and withstands up to 10 bar. Therefore, it is suitable for aquatic sports or use in rainy weather.

●Frequency measuring function

The frequency of an activity per minute such as the number of strokes in rowing or swimming is automatically calculated only by measuring the time required to make three strokes.

●Large-sized three-row display panel

Total elapsed time or lap time in progress, split time and lap time are displayed at the same time, and they can be measured successively without releasing split or lap time measurement.

●Memory recall function ... Up to 300 measurement data can be stored in memory. Measurement data obtained from the start to finish of the measurement is recorded as a block without erasing the data in the previous block, and up to 100 blocks of data can be stored in memory.

This function is very useful for separately keeping the data measured at different time and date.

●Besides, the stopwatch is equipped with such convenient functions as ID No. function useful for keeping the data of individual users separately, and memory capacity indicator and fastest lap time recall functions.

●An antibacterial agent is applied to the case surface of the stopwatches.

※It loses its antibacterial effect gradually over time and the effective period differs depending on the conditions of use.

●Time/calendar display

Year, month, date, hour, minutes and seconds can be displayed while the stopwatch and frequency measuring functions are not used.

・The time and date of starting the measurement of a block of data are automatically stored in memory.

・Before the measurement is started, the block number is assigned to the block of data to be measured.

・Up to 300 data can be stored in memory.

・A block of data includes at least three data. If more than one block is used to store the data, the memory may become full even before the number of lap time/split time measurements in memory amounts to 300.

・The memory clear function is useful in the following cases.

a）When the stored data becomes unnecessary.

b）When the residual memory is not sufficient for a new measurement.

・Once the following steps are taken to clear the data, all the stored data is erased from memory. The stored data cannot be erased one by one or block by block.

・The number of data in memory is shown graphically by the memory capacity indicator.

・Besides the measured lap times/split times, the start time data and block number are also retained in memory as two separate data. Therefore, a block of data includes at least three data.

※If your watch is water resistant (10 bar) and exposed to saltwater or pouring perspiration, rinse it fresh water and then wipe it thoroughly dry.

※As a small amount of moisture is included inside the watch, the inner surface of the glass may be temporarily blurred if the atmospheric temperature is lower than that inside the watch. This does not adversely affect the watch. However, if the blur persists for a long time, we suggest that you have your watch checked by the retainer from whom it was purchased.
