Took a 3-year-old Seiko Perpetual Calendar watch in for battery replacement.  When I dropped it off the employee/owner? told me he could replace the battery, but wouldn't set the calendar.  I told him no problem, as I'd done it before and had the instructions.  I was frankly surprised at his comment.  It's not that tough.\n\nGot the watch back, paid my $17, and left.  When I got home, I noticed the date was stuck between 11 and 12.  No problem, I thought..  I'll do a full reset and just start from scratch.  \n\nThe first simple step is to pull the crown out one click, hold the button for two seconds, and wait for the watch to drive the second hand to zero, and the date to 1.\n\nThe second hand drove to 10, and the date never budged.  The watch worked perfectly until the battery began running low a few weeks ago.  In 30 minutes he managed to mess up the internal workings of my watch.  Guess that's why he was reluctant to agree to actually set it when he finished.\n\nI'll go to a certified Seiko repair facility from now on.
