Seiko 4R34 - List of Time Zone Differences in Major Regions of the World

24-hour hand
1:00
24-hour hand
17:00
a) As an example, if the time of a region you
wish to know belongs to the time zone of
GMT, the time difference from GMT is “0”
and hence,
D = 0
E = C - D = (+9) - (0) = +9
GMT can be read as “1:00” on the rotating
bezel scale.
* If E is a positive number “+”, turn the
rotating bezel clockwise. If it is a negative
number “-”, turn it counterclockwise.
b)
As another example, if you wish to know the
time of the region “Los Angeles”, the time
difference from GMT is “-8 hours”, so D = -8
E = C - D = (+9) - (-8) = +17
Turn the rotating bezel 17 hours clockwise.
(Result: Same as the counterclockwise
rotation of 7 hours)
Los Angeles time can be read as “17:00”.
* When this intended usage is no longer
needed, please return the original position
“24” mark of rotating bezel to 12 o’clock
position.

HOW TO USE
■ In the case of 24-hour hand being set to different time
zone
Three different time zones can be read by turning the rotating bezel.
【Example】 When displaying 10:08 AM Japan time with the hour and minute hands, and displaying Paris
time with the 24-hour hand,
Time difference from GMT of “Paris” where the 24-hour hand is set, C = +1
Time difference from GMT of “Bangkok” that you wish know from now on, D = +7
E=C-D= (+1) - (+7) = -6
Turn the rotating bezel counterclockwise and set.
