Yes. Which watch?

dont know much about helbros but if the back doesnt have a slot to use a small flathead screwdriver to remove the back, take it to a jeweler. if you try it yourself you may scratch the back really bad.

Thank you for contacting FixYa.
You can usually get extra links from JJ/Helbros but for some reason I can not get their website. I would look for a phone # in the manual and call them. They will want the #'s on back of watch.
Best regards. Jewel

You might be able to pop it open with a pocket knife ... don't stab yourself though.

If you go to the web site "www.antique-pocket-watch.com/waltham-pocket-watch.html", you will find information about Waltham watches and if you read the serial number off the movement (open the back and read it off the back plate), you may be able to find out the year of manufacture.

To open the front, try a toothpick in the hole. You will need to get the stem replaced.

To open the back:
Flip the watch over and look around the edge. There will be small slots. A thin blade like a pocket knife will open the back cover. Carefully, put the knife blade into the slot and twist it open. There isn't much user serviceable stuff inside.

Take a closer look at the movement, especially under the balance wheel (use an eyeglass). There should be movement code. By that you can find the real movement manufacturer and the hairspring or balance complete will be easier to trace.
