IMPORTANT
When partially pulled out, the crown can be rotated clockwise to quick-set the
date.
When fully pulled out, the crown can be rotated to adjust the time. This also places the watch into battery
saving mode.
The top pusher button stops and starts the chronograph timer.
The bottom pusher button resets the chronograph timer (Always stop chronograph timer before you reset.)
The central seconds hand will operate as a stop-watch seconds counter when in operation. By default, the
chronograph seconds hand will remain stopped at the 12 o’clock position.
Chronograph minute totalizer. This will count a total of 60 minutes per cycle when the chronograph is active.
24-Hour Indicator. This is not controlled directly by the chronograph buttons. Instead the 24 hour timer
subdial correlates to the main time. For example, if the time is 8:00PM, then the 24 hour subdial will display
20 which essentially is 20:00 with 24 hour time. It’s helpful at allowing to quickly read AM/PM at a glance.
