This is a serious dive watch with some serious specs. The Mido Ocean Star 600 Chronometer packs a 43.5mm stainless steel case, a deep blue gradient dial (other colors are available), and a ceramic bezel built to handle whatever the ocean throws at it. With 600m water resistance, a helium escape valve, and a COSC-certified automatic movement delivering 80 hours of power, it’s as tough as it is good-looking. Whether you’re diving deep or just desk diving, it’s got you covered.
