Pre-owned Breitling Aeromarine Shark Quartz ref A5860511/B14 (1993) is a slight departure from the usual Breitling design language, featuring a design set more influenced by diving than aviation. Here, the watch swaps the signature rider tab bezel seen on many Breitling pilot’s watches for a smoother design. It’s unidirectional and features both a luminescent pip at 12 and a 15-minute dive-time countdown, so it’s ready to keep perfect time while you explore the vast depths of the sea. Furthermore, the Breitling Shark is rated waterproof to 300 meters and features a full set of luminescent hour markers and hands. At 41mm, it makes a bold stance on the wrist, yet it is still quite wearable. Here, it’s paired with a sophisticated leather strap for a bit more versatility than most divers.
