Good Morning [Afternoon, Evening...]
This morning I received four scans from Greg Wade of c.1983 Heuer data cards to add to the page I have already posted on-line.
Each card is notable and significant...
The first card provides us with the first printed information on the exceedingly uncommon and rarely seen Gold 510.508 Lemania 5100 chronograph:
Not many Lemania 5100's were ever put in a gold case!
The second card provides us with perhaps the best explanation of the rationale behind Regatta watches:
It all seems much clearer and easier to understand now!
Thanks are due to Greg for his contribution to the knowledgebase existent on the Internet.
