①Display and
THE STOPWATCH button operation
SEIKO Stopwatch Cal. S143 is a digital stopwatch features a print-out
function that prints out the measurements using the connected printer
immediately after they are obtained. It is also equipped with a large-sized
three-row display panel that can display the split time, lap time and total
elapsed time or lap time in progress at the same time in separate rows, and
a memory function that stores the measurements. In addition, the
stopwatch is water resistant and withstands up to 3 bar. Therefore, it is
suitable for aquatic sports or use in rainy weather.
●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.
●Time/calendar display………Year, month, date, hour, minutes and
seconds can be displayed while the stopwatch not used.
●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.

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.
