They are available to anyone... well, anyone who can order in qty 1 mil or more. <G> Be aware that the mechanism may be problem with these units. I.e. You may have to go through a LOT to find one that you can use, and won't know until you start taking them apart. Problem 1: Many will be "all in one" - that is, the little controller IC on will be part of the LCD itself, and *it* will have the clock functions, etc. all hard coded into its programming. Problem 2: For those that use a separate processor from the actual LCD controller, many of these small "wristwatch" units will use those *$^/&# glue-on electrical connections. Basically it's carbon deposition onto plastic tape, with conductive adhesive. Also used in tons of pocket calculators, I am forever finding it to be the most common failure point in older units. I have NEVER been successful at long-term re-attachment of those LCD displays. [And if anyone has a solution, PLEASE let me know. <G>] jmk ----------- James M.
