Breitling Superocean Automatic Rainbow

In the 1960s, the new sport of scuba diving was all the rage. For divers, timing was everything, and Breitling set out to give them the most clear-cut dive watch possible by eliminating any feature that didn't support their lifesaving needs underwater. What remained were clean lines, chunky luminescent indexes, squared-off hands and a high-contrast dial ring, all aimed at maximum legibility. Practical, yes. But what people really fell in love with was the look.
