SCREW LOCK TYPE CROWN

Some models may have a screw-lock mechanism that can securely lock the

crown by screw when they are not being operated.

Locking the crown will help to prevent any operational errors and enhance

the water resistant quality of the watch.

It is necessar y to unlock the screw lock t ype crown before operating it.

Once you have ﬁnished operating the crown, make sure to relock it.

How to use the screw lock type crown

Keep the crown securely locked unless you need to operate it.

[How to unlock the sc rew lo ck type crown]

Turn the crow n counterclock wise. The crown is unlocke d and can be operated.

[How to lock the screw loc k type crown]

On ce yo u have f inis he d oper atin g the crow n, tu rn it clockwise w hile g ently pre ssing it in toward the wa tch body until it s tops.

* When locking the crown, turn it slowly with care, ensuring that

the screw is properly engaged. Be careful not to forcibly push it in, as doing so may damage the screw hole in the case.

Tachymeter scale can be used only when the time required is less than 60 seconds.

Ex. 2: If the measuring distance is extended to 2 km or miles or shortened to 0.5 km or

miles and STOPWATCH second hand indicates “90” on tachymeter scale:

“9 0” (tachymeter scale ﬁgur e) x 2 (km or mile) = 180 km/ h or mph

“9 0” (tac hymeter scale ﬁgure) x 0. 5 (km o r mile) = 45 km /h or mph

TELEMETER

(for models with telemeter scale)

The telemeter can provide a rough indica tion of the distance to the source of

light and sound.

The telemet er ind ic at es the di stan ce from your location to an ob je ct that

emits both light and sound. For example, it c an indicate the distance to the plac e where lightnin g struck by mea suring the time e lapsed af ter you see a ﬂash of lightning until you hear the sound.

A ﬂash of lightning reache s you almos t immediately w hile the sound travels

to you at a speed of 0. 33 km /s econd. The distanc e to the sourc e of the light and sound can be calculated on the basis of this dif ference.

The telemeter scale is so graduated that the sound travels at a speed of 1 km

in 3 seconds.*

*Under the condition of temperature of 20°C(68°F).

Ex. 2: If 15 jobs are completed in 20 seconds:

“18 0” (tachymeter scale ﬁgure) x 15 job s = 2700 jobs /hour

CAUTION

The telemeter provide s only a r ough indic ation of the distance to the

plac e wher e ligh tn in g struc k, and there fo re , the i nd ic ation cannot be used as the gui de lin e to avo id the da nger of lightn ing. It sho uld als o be noted tha t th e sp ee d of the sound diff er s depe nding on the temperature of the a tmosphere where it travels.
