Please note that this is the first version of the Commodore module with a red plexi on top of slightly larger LEDs.
The later version had smaller LEDs and plexi prisms to enlarge the digits and where fitted to cases made in France and the last ones from Hong Kong.
The module thickness is different so if I correctly recall some troubleshooting in the past this early module will rattle in most Commodore watches.
This one will need a thinner USA case with Palo Alto (California) engraved on the back.
