Press the button using an object with a long tapered tip. How to use the button
With each pressing of the button, the seconds hand advances 1 second (+ 1 hour) in the clockwise direction and the time advances 1 hour.
The position of the seconds hand shows the difference. Please set it by referring to List of time zone differences in major regions of the world.
Also while the watch is working, the seconds hand can be moved.
The radio signal transmitting station can be changed by setting the time difference. When setting a time difference for regions other than the radio signal reception ranges, the radio signal reception function will not work.
When setting the Daylight Saving Time (DST), add one hour to the time difference of the target area.
When the seconds hand is at 13 seconds (UTC +13 hours), press the button to move it to the 49-second position (UTC -11 hours).
After one minute, the watch switches to the one-second interval movement.
When the date is changed, it is also moved.
Only the 1B22 and 1B32 are date-displaying models.
