BASIC OPERATION (HOW TO SET THE TIME/HOW TO RECEIVE GPS SIGNALS, ETC.)
This watch can be set to the precise current time by automatically receiving GPS signals by exposure to bright light
outdoors under an open sky to adjust the time.
In addition, when the watch is concealed under a sleeve and the dial is not exposed to sufficient light even if outdoors
under an open sky, the watch stores the time of the previous successful manual time adjustment (or time zone
adjustment), and automatically starts time adjustment at the same time.
 In a place without good visibility, GPS signals cannot be received.  Place where GPS signals can be easily received/Place where GPS signals cannot be

adjustment will be performed the next day or thereafter.

the last time.

can be easily received under an open sky.
