Surface interval time
No fly time
No fly mark
Current time
The surface mode is used to display elapsed time from the end of the most recent scuba
dive (S.I. time) and the amount of time remaining until boarding an aircraft is permitted (no
fly time).
DANGER
Avoid traveling in an aircraft while the surface mode is activated.
Traveling in an aircraft without allowing sufficient time to rest after diving results in the
risk of decompression sickness. It is recommended to avoid traveling in an aircraft for
at least 24 hours after diving whenever possible even if the surface mode is no longer
displayed. There are no rules for completely preventing decompression sickness
caused by flying in an aircraft after diving.
* The surface mode is preferentially displayed at all times after scuba diving.
* When the no fly time reaches 0 hours 00 minutes, the watch exits the surface mode, and
returns to the time mode of the standard mode. The surface mode is not displayed after that
time until completion of the next scuba dive.
* If the watch is insufficiently charged (when the level of the charge level indicator is ),
in the lower left corner of the display in the surface mode changes to to indicate
that the watch should be charged.
