Product Details
The new Breitling Superocean retraces the Slow Motion's celebrated design codes, while adding modern features, like a ceramic-inlaid bezel and brightly coloured dials. Broad hands and indexes in luminescent Super-LumiNova® allow for easy readability underwater. The watch is water resistant to 300 m (1000 ft), as well as being shock-, sand- and saltwater-resistant.
The bronze version uses a special alloy that has excellent resistance to corrosion, yet will still develop a subtle patina over time that makes the watch even more unique. The two strap options (rubber and metal bracelet) have a folding clasp that allows for micro-adjustments of up to 15 mm for easy wear over rashies and wetsuits. Its scratch-proof ceramic inlaid bezel will never wear or fade. For safety, the bezel is uni-directional on most sizes and bi-directional with a patented lock on the 46 mm. Best of all, this is no longer strictly a dive watch—surf with it, swim with it, hit the beach bar with it, and then wear it out to dinner. The Superocean perfectly balances the nostalgia of its heritage with a fresh new look.
