Hi Dan,
Congrats on the purchase. Calibre 15 does not have a quick-set function for the date, so yes, please don't try and pull it out any further! There is a way to do a "semi" quick-set.
Wind the clockwise hands through to 12 until the date changes once, then rewind anti-clockwise back to approx. 10 and then forward past 12, then back to 10, etc until you have the date right.
