Here is a great quick-reference archive of movements that I found on the internet. Seiko, Citizen and Orient are well represented but so are many, many others...non-Japanese. Each entry that I have looked at has a picture with a small description of the movement which includes dimensions, frequency and complications found, as well as year introduced.
Just thought it would be useful to someone...
