Comments about the data
The mounting frame with parts of the date assembly is part of the calibre, and simultaneously the highest part.
indirectly driven minute allows a very big balance
two barrels coupled in parallel use the remaining space most efficiently
if 26 jewels: 5 hole jewels for horizontal guide of the date disc (Fig.3, A in fig.4) and 4 cap jewels for vertical guide (Fig.3, B in Fig.4)
Fig.3 shows likely the most complicated assembly ever to advance the date with a pusher.
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. However, if you're done you can make a photo like Fig.3 before assembling the calendar assembly.
