I recently purchased this booklet of A-Z LED watches "Technical Bulletins" from the manufactures. The pages of the booklet are made up of what was submitted to the AWI on how the watch would work, how to diagnose problems with a non working or malfunctioning module (Like REPLACE WITH A NEW MODULE IF BROKEN), and or simply how to set the time of a certain LED watch. It has great information for some really nice watches, For certain watches it has simple-to-complex blueprint or schematic for the watch submitted.
I thought I would share a few pictures of what I'm talking about, and eventually (NOT RIGHT AWAY), I will scan them all into my computer. My scanner is on the fritz, so I will be having to purchase a new one, and it will be awhile before that happens. When I have it available, I will let everyone know who's interested.
