Checking the Amount of Winding

Power Reserve Indicator

This function displays the amount of remaining mainspring winding as a time.
It shows at a glance how much more time the watch will run.

• Maximum continuous operating time

  • Maximum scale mark on the power reserve indicator
    (Scale mark on opposite end of zero mark)

• Movement of the power reserve indicator hand
  

A	Power reserve indicator hand
	1	Winding up the mainspring: Movement in maximum continuous operating time direction
	2	Mainspring unwinds: Movement in zero scale mark direction

TIP

• Depending on the continuous operating time, the power reserve indicator hand may go past the zero scale mark but this is not a malfunction.
• The remaining continuous operating time indicated by the power reserve indicator hand may differ from the actual remaining continuous operating time. Use it for reference only.
