Getting Ready to Set Time on my new Klaus Da Vinci Perpetual Calendar..HELP please

Hi all...getting ready to set the time on my new Klaus Da Vinci PC...I will be waiting until after 2 AM.
The manual instructions are a bit vague.
Set time first to 4:40...OK, I can do that.
Pull crown out to position 1 (first crown stop after winding position), rotate crown slowly, and calendar will advance in steps. Set yesterday's date, also making sure month and year are correct

How do I make sure month and year are correct? I don't want to mess with the watch for fear of advancing too far, and it has to go to IWC service.
Any suggestions?
Thanks
Alan

Got it figured out...just takes a while to advance it to the right day/date!

Whew -glad you got this right. It advances slowly, so if you go to far you usually can just put the watch away and wait for time to catch up in a few days once the watch stops.

Nice watch, by the way.

Good morning Michael.
The watch was at "April 2011", so I just took my time advancing day by day till I got till August 17, 2012...then I advanced to the next day by moving the hands forward...I was indeed worried about overadvancing! My worst fear was that I would see 2013 in the year window!
Best regards,
Alan
