Did I damage my IWC Aquatimer Chrono ref 3767-11 ?

Hello everyone,
As painfully and humiliating as it sounds I think I might have damaged my IWC Aquatimer ref 3767-11. I believe I might have changed the week day on the watch between the forbidden hours of 8pm to 3am and now starting to realize that when I set the crown on the outer most position to set time and turn the movement, the date does change at 12am, but the week day changes at 9am. It seems very obvious I damaged the watch, right? Please let me know if there is any way of fixing this. I am beating myself here this what is such and icon and cost so much should have done more research before using it. Expert advice is needed please.

Thanks in advance,

Gus

I'm no expert in watch mechanics,but my initial move would be to let the movement,provided there isn't any problem with winding,is to let the watch run a twenty four hour cycle and see if there isn't any resistance to the mechanism.
Good luck.

You'd better bring the watch to your AD for a repair and not push your luck anymore. You won't make it by yourself neither will this correct by itself.
