What makes the Ocean Star 600 a serious dive watch? It's water-resistant to 600 meters (60 bar), fitted with a helium escape valve for saturation diving, COSC chronometer-certified for precision, and uses the Caliber 80 Si with a silicon balance spring for anti-magnetic accuracy. The unidirectional ceramic bezel is filled with Super-LumiNova Grade X for maximum legibility underwater.

What's special about the Caliber 80 Si COSC movement? The Caliber 80 Si is Mido's COSC chronometer-certified automatic movement with a silicon balance spring. Silicon is non-magnetic, lighter and more temperature-stable than metal alloys — delivering superior precision (±4/+6 seconds per day per COSC standard) and resistance to magnetic fields. 80-hour power reserve.

Does the 43.5mm size wear well day-to-day? Yes — at 43.5mm this is widely considered a bold, presence-rich size, suitable for most wrist sizes and easy to wear with formal or casual attire.
