●Cal. S149issuitablefor measuringmassive timedate
inaroadrace,marathonrace,etc.
①Withtheuseofthebuilt-inprinter,themeasured
timedatacanbeprintedoutassoonastheyare
obtained.
②Year,month,dateandtimewhenthemeasurementis
startedcanbeprintedout,andtherefore,itiseasytofile
andkeepthedata.
③Anautostartfunctionisprovided.Bypresettingthe
timewhenthemeasurementisstarted,thestopwatch
startsmeasuringautomaticallyatthedesignatedtime.
④Memory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.
⑤Besides,thestopwatchisequippedwithsuch
convenientfunctionsasID No. functionusefulfor

●Usedwithoptionaldevices,thestopwatchcanperform
variousfunctions.
①By connecting the stopwatch to SEIKO Digital
StopwatchCal. S143, etc.,morethantwostopwatches
canstartmeasuringsimultaneouslyatafixedtime.
Therefore,itispossibletomeasurethetimeinaroadrace
ormarathonatdifferentcheckpointsmoreaccurately.
②Connectedwitha grip switch(optionalaccessory),the
stopwatchcanbeoperatedmoreeasily.
③Withtheuseofapaperextensionholder(optional
accessory),massivetimedata(approximately2,500data)
canbemeasuredsuccessivelyatatime.

11.REMARKSONTHEBATTERIES
（１）Batterylife
Whena newnormal batteryis installed,the stopwatchwill

Whenalkaline manganese batteriesare used, itcanprint
approximately20,000lines(approx.28rolls).
＊Itthe printerisusedat extremely low temperatures, thebatterypower
