Using the Crown

The crown of this watch has a button part and a ring part. You can use the crown’s button and ring to perform a number of different crown operations.

ENGLISH

Locking the Crown

Important!

Push down on the ring as you slowly rotate it. You should be able to feel it screwing

securely into place. You should normally have the crown locked during normal daily use. Leaving the x crown unlocked creates the risk of unintended operations or even damage due to impact.

Pulling the Crown Out

Rotating the Crown

To lock the crown, push down its ring part as far as it will go as you rotate the ring away from you until it is relatively tight. While the crown is locked correctly, the only crown operations possible are pressing the crown button and unlocking the crown.

After unlocking the crown, grasp the ring and pull the crown out.

With the crown pulled out, grasp the ring and rotate the crown towards you to move the hands of the watch. You can also perform high-speed hand movement using the operations described below. Note that there are two levels of highspeed movement (High-speed 2 is faster).

Use High-speed 2 when changing the minute hand setting in the

Timekeeping Mode, Timer Mode, and Alarm Mode.

Charging the Watch

The face of the watch is a solar panel that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.

Charging Guide

Power Levels

Moves at two-second intervals.

E-18

Whenever you are not wearing the watch, be sure to leave it in a location where it is exposed to light.

Best charging

performance is achieved by exposing the watch to light that is as strong as possible.

You can get an idea of the watch’s power level by observing the movement of the Timekeeping Mode.

power is at Level 2, which is quite low. Expose the watch to light as soon as possible so it can charge.

When wearing the watch, makes sure that its face is not blocked from light by the sleeve of your clothing.

The watch may enter a

sleep state (page E-22) if its face is blocked by your sleeve even only partially.

Warning! Leaving the watch in bright light for charging can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.

Important!

Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down. Storing the watch for long periods in an area where there is no light or wearing it in

such a way that it is blocked from exposure to light can cause power to run down. Make sure that the watch is exposed to bright light whenever possible.

When power drops to Level 3, all functions will be disabled but the watch will x continue to keep time internally for about one week. If you recharge the battery sufﬁ ciently during this period, the analog hands will move automatically to the correct setting and regular timekeeping will resume. After one week, all settings (including timekeeping) will be cleared. Recharging the battery will reset all settings to their initial factory defaults. A short while after exposing the watch to light after its battery charge has run down

will cause the xx Second Hand to move counterclockwise until it stops at second 57 on the face. This indicates that charging has started. See page E-21 for information about required charging times.

Operation Guide 5143

Power Recovery Mode

The watch is designed to go into a power recovery mode that stops hand operation temporarily whenever power suddenly drops below a certain level due to overuse of the alarm tone over a short period. Note that all operations are disabled while the watch is in the power recovery mode. The hands will move to the correct positions and the watch will resume normal operation after power recovers (in about 15 minutes). Putting the watch in a location where it is exposed to light will help power to recover sooner.

Power Saving

Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving.

There actually are two sleep state levels: “second hand sleep” and “function sleep”.

Elapsed Time in Dark Operation

60 to 70 minutes (second hand sleep)

6 or 7 days (function sleep)

The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch x is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state. The watch will not enter a sleep state while it is in the Stopwatch Split Mode,

Stopwatch Lap Mode, or Countdown Timer Mode.

Mode Disk Pointers

The vv Mode Disk uses three different pointers to indicate a variety of different information: a mode pointer, a split pointer, and a lap pointer.

Mode Pointer

The mode pointer is in a ﬁ xed position. Whenever you enter a mode, the v Disk will rotate until the current mode indicator (AL, TR, ST, TM, or WT) is aligned with the mode pointer. The mode pointer is also used for indication of standard time (STD) and summer time (DST).

Split Pointer

The split pointer is marked on the Split Mode (page E-46), it indicates the current status of the stopwatch operation. While a normal stopwatch elapsed time measurement operation is in progress, the split pointer will point to RUN. When a split time is indicated by the hands (which are temporarily stopped), the split pointer will point to SPL. Stopping the elapsed time measurement operation will cause the split pointer to move to STP (stop).

Lap Pointer

The lap pointer is marked on the lap time measurement in the Stopwatch Mode, the lap pointer points at the current lap number (1 through 5). If the current lap number is greater than 5, the lap pointer will point at
