I actually have an even larger picture of the gear diagram, but it is ten (10) times this size (100 times the area) and it is too large to be viewed by a web browser. I also have a slightly larger picture of the watch cut, but it doesn't show any more details, only artifacts (dots) from the original print. If you want to learn more about how a watch is put together and works, the TimeZone web site has an excellent Illustrated Glossary of Watch Parts.
