I think it is a good idea, the module is after all the most vital part of a working watch!
Hopefully within the next couple of days I will find the time to get the ball rolling by photographing a Hughes 29mm module (might of well start with one of the more common modules) and posting the information you suggested along with the photographs. I will make a fresh listing with the title 'Watch Module Database' and ask Kasper if he could make it a 'sticky' so it remains at the top of the page, if others then want to chip in with their own photo's or fill in any gaps in mine or others knowledge I will try to edit the photo's and information as they come to make/keep it user friendly (if required). Once the data base is under way it will then be easier for Hanno to use the information that has already been posted to create something better or more permanent should it require it.
I would suggest starting with a database for LED modules and if successful branching out with a fresh database for LCD modules.
Your/others thoughts.....?
