I'm hoping Mark that you've discovered this little shortcut yourself - if you manually change the date on a Cal. 11 or 12 movement you can save yourself from scrolling 24 hours to move the date forward 1 day. Once the date has fully flipped forward 1 day, wind the watch back to a bit before the 10 o'clock position and then forward again, as you pass the 12 o'clock position the date scrolls again. You can repeat this process to quickly set the date on your watch. Personally as a multiple watch owner that tends to change watches day to day , i dont usually set the date on mine.
Hope this has helped if you didn't already know. - Darren
