I got a Poljot Aviator III Chronograph with the 3133 movement.
Watch works fine when freshly wound, but when into 30-40hrs of its 60+ Power reserve, starting the chronograph would cause the time to stop (main seconds hand at 9 o'clock position). When the top chrono button is pushed again, the time continues as per normal.
Does a lower power reserve cause the 3133 movement's chronograph to stop functioning??
