Vintage Heuer Ad- Heuer Aquastar Regate

Heuer's Regatta model uses the 5 circular windows for yacht timing- indeed, it's the same idea on today's Calibre 72 Aquaracer.

Here is where it started- the Heuer Regate...or more precisely, the Aquastar Regate. Yes, it was the Aquastar brand that came up with the idea.

Heuer distributed their watches and added the Heuer shield to the logo on the first models before launching their own "Regatta" watches.
