The Henry is equipped with a specific, also tonneau shaped, very smooth hand-winding movement including the famous and revolutionary Straumann double hairspring (in order to exclude gravitational influences).
The movement provides hours, minutes, small seconds and last but not least a power reserve indicator, which is located at the movement side. Due to a large-volume spring barrel, the movement has a power reserve of four days.
Moser introduced the double hairspring in 2009 in the tonneau shaped model Henry.
But constructing and regulating the spring turned out to be nearly as expensive as producing a tourbillon.
Therefore the Henry model was discontinued soon....
