How do you know this is a CompuChron? I couldn't find any marking like my other CompuChrons.
Feel free to check my ebay feedback for other LED watches sold.
It's not a CompuChron - they have two screw in battery hatch, with a double battery hatch below them with a sliding catch for the other two cells(4 total). Most likely a Belair or Mercury case. Hughes module in any case.
