HELP: VC Patrimony, power reserve with date

I purchased my first VC watch (ref 47200/1, 18k Patrimony power reserve with date).  It has the caliber 1127 movement (auto, 45 jewels) which I understand is based on the JLC caliber 928.

Setting the date: This watch is different from any other watch I currently own or have owned.  To set the date, I need to pull out the winding stem and then depress the register.  If I do this, I can advance the date as much as I wish.  If I do not pull out the winding stem, depressing the register will only advance the date by one day - even if I depress the register more than once.  I assume this is a safety mechanism as the watch movement stops (hack system) when the winding stem is pulled out. I own other high quality watches where the date is changed with a register rather than the crown and they do not require this.

I want to make sure everything is "OK" with the watch.  Is this common for the caliber 1127?  Do all VC watches with date that have a register operate like this?

Best regards, TD

What do you mean by "depressing the register". To change the date you

either have a little button on the side which you need a small pointy object to press (is this the register you refer to?) or you just need to pull the crown out one position and turn.

By "register" I am referring to the little button that is to the right of the crown.  I use a toothpick.  On my other watches, the date changing function is via the crown.  I pull the crown out, the hacking system stops the movement, one pull changes the date, two pulls changes the time. On the Vacheron I just purchased, the crown only changes the time.  I pull the crown out, the hacking system stops the movement and then I can press the "button" to change the date as many days as I wish.  If I do not pull the crown out and press the button, the date will only change by one day even if I press the button again. I figure this is a safety mechanism as the movement is still running but I want to ensure this is the way the watch is suppose to work.
