Hi, I am a seiko 8f33 perpetual calendar watch. I just got it back from Seiko...had the battery changed and new band. the problem is that I tried to set the date and the watch stopped working. Does anyone know what to do?

What a great watch! It has a super-fine piezo-electronic motor to move the date wheel! Very cool. Its quite a show to go through the date/leap-year check, and then observe the watch catch back up to the correct time afterwards. Battery lasts ~five years.
I downloaded the manual (your model number on watch back) after a short search online (beware of trojans/viruses).
Setting after a battery replacement requires shorting certain pins inside the watch to set the leap-year, and date. The back unscrews, and may require the special watch-wrench, available online. I unscrewed mine VERY CAREFULLY with fine pliers, confirming that I was doing this in a clean, dust-free location. The instructions are quite specific, must be followed carefully to set up correctly. Have a fine wire jumper to set the leap-year. I learned this because I did not want to pay an inexperienced jeweler $100 to replace the battery.

You can not set the date..it MUST be returned to Seiko for repair. A perpetual calendar watch does not lose the date if it does something is wrong. Seiko will repair for you.

Your watch has a perpetual calendar which can only be set from inside the watch using the touchpads around the edge of the movement.

Try pulling the crown wheel (winder) to position 2 (1 is fully in, 3 is fully out and 2 is in the mid position).

Turn the winder anticlockwise slightly and this should move the date until it is the correct position.

mcdevito75 here, Your Jeweler had to mention your watch would go to Seiko for repairs. Seiko should notify you or your Jeweler with the repair particulars.
