Hi,
I have a very strange problem with that watch.
I realized that the time doesn't move on!
It sets fine , once set , the second starts normaly but at 19th second ,it comes back to 0 !!!
So never a minute passes by????
I suspect a weakness in the design of the module.
I had it in a lot of Microsonic and Gruen led (the 2 must have merged in the past because some are marked Gruen on the face, come in a microsonic box and have the kind of the microsonic thunderbolt on the back:all mixed up)
It apparently came from an old stock from the factory maybe a prototype?
Any clue on that?
