Has anyone ever taken one of these apart? I need to go into mine and don't want to beat it up, but cannot seem to see just how to open it up??

I realize that is a valid consideration, but hoped to get it open and back together still looking good. Sooooooooo, anyone had one open? How'd you get it open?

If you are talking about the Competition Electronic brand, mine has one screw in the battery compartment.

Jim, are you saying that's it? I took that one out but it still seems solidly held together. Do you have a picture of it separated?

If memory serves, the two halves of the clamshell are solvent bonded or ultrasonically welded.  

Roughly 3 years ago I accidentally left mine outside overnight and it rained.  The chronograph wouldn’t turn on so I opened it up and cleaned and dried everything.  That did the trick.  I just remember it didn’t want to come apart and I probably would have abandoned the attempt were it not a lost cause otherwise.

So how did you get it apart? If it was indeed solvent bonded or ultrasonically welded, what did you use? Want to use the least damaging approach.

A thin blade of some kind.  I used a putty knife.  The bond is brittle.
