High-speed Movement
When rotating the crown to move the hands of the watch, you can use the operations
described below to move the hands at high speed, either forward or back. There are
two high-speed levels: HS1 and HS2 (faster than HS1).
To start HS1 high-speed movement
While the crown is pulled out, rotate it rapidly three turns away
from you (for forward movement) or towards you (for reverse
movement). High-speed movement will continue even if you
release the crown.
To start HS2 high-speed movement
While HS1 high-speed movement is in progress, again rotate
the crown rapidly three turns in the same direction as the
current HS1 movement (away from you for forward movement
or towards you for reverse movement).
