Comments about the data
indirectly driven minute allows a very big balance
two barrels coupled in parallel use the remaining space most efficiently
automatic with two roller freewheels (Fg.4)
Attention! Never, never ever unlock the stem unless you have pulled the crown to setting position. And never insert the stem without pushing the release button, even not if the collar towards the square is conical to lift the set lever. Else you have a high chance to mix up the parts of the setting works, and rearranging them is much more troublesome than in most other movements.
