You cannot test any watch over a few hours now before you go running to the AD do a proper test.First manually wind your watch 40 full crown turns clockwise only.Then set time with a reliable time source for this test any quartz watch will do sync both watches.Then you must wear for a min of 8 hours per day,check time daily with setting source over 5 days.Then average out the lose or gain over those 5 days.If its over a Average of between -4 to +6 seconds over a 24 hour period then watch needs very simple regulation.Which in reality should not take longer than 30 minutes start to finish including pressure check.But if it goes off to the RSC expect to be 4 weeks or longer without your watch.
