With origins dating to the late 1950s, the SuperOcean collection is one of Breitling's longest-running and most popular collections. A purely dive-focused collection, the design family has long balanced the well-respected chronograph maker's catalog, providing the market with years of interesting, highly water-resistant designs executed in both standard diver and diver chronograph styles. In 2010, the SuperOcean base design saw its supposed successor with the debut of the SuperOcean II, which went on to become an independent collection in 2015. In 2017, Breitling began phasing out and evolving the SuperOcean II collection in favor of the firmly vintage-inspired SuperOcean Heritage Collection; this novel group recalling aesthetics seen in the dive family's earliest years, and significantly following up on the original SuperOcean Heritage watches introduced a decade earlier.
