You should check the PP website as they show you all four versions of the Star Caliber together! You can also order the book pertaining to the watch. There is also a section devoted to it in the PP Watch Time SE magazine.
Wow! What a great collection, all in one place! love that pocket watch sitting majestically in its own display case. And the box that comes with it, too. Carved gold inlays, chain, stylus, etc. looks brand new. Bob
The 3rd most complicated mechanical watch in the world! Just beautiful! I believe only the Supercomplication (Henry Graves Jr) and the Calibre 89 are more complex, both of course are PP watches.
