Question
I'm trying to install a replacement battery in a womans Pulsar watch and can't seem to make closure of the back.  Is there a trick to doing this?

Answer
Hi Jim,

First and most important, make sure there is nothing on the case back that would prevent it from closing.  One piece of lint is all it takes.  Remember, a watch is an engine in miniature.  Small obstructions mean a lot.

Watchmakers use a case press because, unless you have very strong hands, you won't be able to press the back on.  

If you don't have a case press, look at the crystal on the watch to see if it is higher than the case.  If it is not, you can wrap the watch in a t-shirt or handkerchief and put the watch between 2 hard surfaces to get the leverage you need to close the case.  Really think this through before you proceed.  You are trying to jury rig the procedure so be careful and go slow.  Look to make sure the case back is lined up properly. Make sure there are no obstructions.

If the crystal is higher than the case, you need to take it to a person with the correct tool so you don't break the watch.
