..

you can set the date of your watch by pulling the crown on its middle position and turn it until it reaches the exact date, remember there are three position of the crown, first the normal position, the middle and the out position. push the crown when you done. i hope this will help you.

If you will browse through my Tips and Tricks, you will find the link to Pulsar watch manuals.

Take the four-digit caliber number from the watch back, and go to this link. You download a complete PDF with all your Settings Instructions:

Good luck, Bill

Pulsar are made by Seiko and support can be obtained from their web site. (The number your quoted is a Seiko number- all Pulsar models seem to start with two or three letters).

Put "www.seiko.co.uk/support/instructionbooklets" into you search engine and you should come to the Seiko instructions list. Scroll down to find your watch and download the instructions.

You can find your manual here.

you can print out instructions from Seiko website.

On the Pulsar website they tell you that the manuals are organized by "calibre" number. I did a search and I think the calibre number of your watch is NX14. If that's right, here's a link to the manual:

If that's not the right calibre number then look at this Pulsar site to find out what is the right calibre number:

By the way, Internet Explorer kept telling me I need to download a Language Pack when I clicked on the above links. I just hit "cancel" and everything loaded fine.

At last count far less than half of the solutions I've provided have gotten a vote or a response. I think the benefit of this site is when a solution (right or wrong) get's some feedback so others can learn from it...my two cents.
