Vintage vibes with a modern kick, the Longines Ultra-Chron brings back the brand’s iconic high-frequency dive watch from 1968. Its 43mm cushion-shaped stainless steel case houses a black dial with a sapphire bezel insert, keeping things sharp and legible. Under the hood, the high-beat Calibre L836.6 hums at 36,000 vibrations per hour, delivering serious precision with a 52-hour power reserve. With 300m water resistance, it’s a retro diver that’s built to perform.
