Just wondering what happens when you....

Pull out the crown to adjust the time while the chronograph is engaged?
If the chronograph movement is hacking eg: Rolex 4130, 7750 etc.
If the chronograph movement is non hacking eg: el primero.
If the chronograph movement is modular eg:ETA base + DD module, AP 3126/3840.

Anyone knows? Anyone dares to try? More technically savvy members can guess?

Everything stops. I am pretty sure Seiko chronograph with vertical clutches do. For 7750, setting time just moves the hour and minute hands, nothing else will move. If I remember correctly, for Daytona because it uses vertical clutches too , setting the time set the chronograph hands too.

When the crown is pulled out, a stop lever/ brake, will stop the balance.
The chronograph parts will still be engaged on the movement side, which is the stuff you see from the caseback.
Setting the time engages parts on the dial side, it should not affect the chronograph parts. after setting the time, push back the crown and it should function as normal. Maybe a little slower to catch back the time since most things are engaged.
Modular movements have the chronograph parts on top of the dial side. still, shouldn't be too much of a problem to adjust the time when chronograph is running.

Well... have you tried yet? It's still under warranty and a screw-up is a good excuse for a trip to Singapore...
