From my personal collection, and a prototype that was never produced.

This was a prototype from a failed company, the production watch never made it.  

Specs:  7750 Automatic Chronograph Measures 42 X 42 X 15 plays slightly larger than dimensions suggest.  Comes with orignal unworn denim signed Jublion strap.  

This watch was originally a cheaply done black PVD I had that removed - you can still see some of the evidence on the crowns.  

The watch isn't mint but presents fine.  I see this watch as an inexpensive way for a new collector to get into a 7750 movment for a bargain price.  The watch sets and runs fine, chronograph works and resets fine.
