repair of HP-01 watch


I have an HP-01 watch that after putting in new batteries worked for about five minutes and the display went out. I need to send it to someone who can repair it. Any suggestions?


I had a contact problem with the battery contact on mine (It didn't work after closing). I solved it by putting a piece of paper into the watch at the right position.

The paper presses against the battery contact somewhere.

I'm pretty sure, you inserted the battery right, when it worked some minutes.

Mine works, not like a charme, but like a HP LED watch.

Let us know, if it works.
