<Notes before use—Protective stickers>
Prior to the watch being shipped from the manufacturing plant, its glass, case, metal
band, and metal parts of the clasp are covered with stickers to protect them from getting
fingerprints or scratches during transit from the plant to the store.
If the watch is worn without first removing these stickers, perspiration or moisture may enter
the gaps between the protective stickers and the parts, which may result in a skin rash and/or
corrosion of the metal parts.
For this reason, please be sure to peel off the stickers before wearing the watch.

Notes on the time signal reception
Receiving the time signal
There are three ways to receive the time signal:
• The second hand indicates the reception result (OK/NO). (See page 11.)
Methods Explanations
Automatic reception Receives the signal at 2:00 a.m. every day. If reception is
unsuccessful, the watch tries to receive at 3:00 a.m. and 4:00 a.m.
On demand reception Receives the signal when you want to adjust the time and date.
See page 24.
Recovery automatic
reception
Automatically receives the signal once after charging when the
watch stops due to insufficient charge.
* These reception methods are possible only when the crown is in position .
• The watch will not receive the time signal when in a low charge state as indicated by the
second hand moving in two second increments (the insufficient charge warning). Charge
the watch before reception.
EN_H145[DOM]-f.indd Sec1:16EN H145[DOM]-f.indd Sec1:16 11.3.29 5:17:33 PM11.3.29 5:17:33 PM

• The automatic reception function and recovery automatic reception function cannot be
deactivated.
• Even when this watch receives the time signal successfully, the accuracy of the displayed
time will be dependent on the reception environment and internal processing.
• If the watch is not able to receive the signal, it will operate normally within an accuracy
range of ±15 seconds per month.
When receiving the time signal
Remove the watch and place it on a stable surface where
it can receive the signal better, such as next to a window.
• The reception antenna is located at the 9:00 position
of the watch. Place the watch with the 9:00 position
facing toward the station.
• Do not move the watch during time signal reception.
