as all is programmed to change all together with the ALONE pusher.
I sold mine in WG, as if you do not use the watch for a long time (turn-over period) you have to push any missing date with the pusher.
Or to put the watch on the winder.
In fact, the year is a warranty to have a correct Perpetual Calendar with moon phase in accordance.
If you push too much, you have to wait the date: no correction back is allowed.
I like this new case and black dial and the new rotor. The old version front dial had more charm and also its officier case-back was a bonus IMHO.
Best,
