Indicator hand showing North. (E') 

Adjustable second hand. (F') 

This chronograph is fitted with a small red indicator hand E' bearing the letter "N"; this hand completes one turn of the dial in 24 hours and is adjusted by means of crown O. Bearings may be taken by turning the watch, held horizontally, so that the hour hand points towards the sun, in which case the direction of North is shown by the indicator hand E'. 

This model is so constructed that the small second hand F' can be set to the exact time. Crown G' is simply pushed in and turned; this moves the second hand F', which can thus be set, for example, to correspond exactly to the time given by the time signal.
