How to set the correct time by receiving GPS signals
To set the correct time and ensure that the GPS signal is being received from the satellites, start by going outdoors with a clear view of the sky so the watch can easily connect with the satellites. Press and hold the top right-hand pusher for 3 seconds.
The second hand will move to 12 o’clock and the indicator hand will point to 1. The watch will search for GPS signals. This operation can take up to one minute.
When it is complete, the second hand will either point to Y, if it was successful, or N if it was not. These steps can be repeated if needed.

The indicator hand will point to 4+ and the watch will search for GPS signals. You will see the second-hand point to the number of satellites the watch is receiving, at least four are required for time zone adjustment.
This operation can take up to two minutes, when it is complete the second hand will point to Y if it was successful or N if not.
These steps can be repeated if needed.
How to adjust the time zone manually
The time zone can also be adjusted manually by pulling the crown out one click. Turn the crown clockwise to advance the time zone and turn it anti-clockwise to move the time zone backwards. Once complete, push the crown back in.

How to switch between the main dial and sub dial
The time shown on the main dial and sub dial can be switched. This can be useful when travelling for keeping local and home time easily visible depending on the location.
To change this, press both pushers at the same time for one second. The main dial’s hour and minute hands, sub dial, day, and date will switch, in that order.
The times can easily be switched back by repeating this process.

How to read the charge indicator hand and charge your watch
The indicator hand will help identify if your watch needs charging. To receive GPS signals, the charge indicator hand will need to be on either the full or middle position on the charge scale.
The indicator will point to low when the watch requires charging, and the second hand will move at 2 or 5 second intervals when it urgently needs to be charged.
The watch can be charged under natural sunlight or under a bright light source. Ensure that the light source doesn’t get too hot, an LED light is ideal for this. It will take the watch around 50 hours to fully charge in sunlight and 5-7 days to become fully charged in artificial light.
