Colorful above the waves but designed to dive in to 200 meters, this promaster aqualand men's watch from citizen showcases a blue dial with luminous marker, hands and date window. Set in a 46mm stainless steel case topped by a mineral crystal, the watch includes a helium valve, oversized crown and function pushers for maximum depth memory, rapid ascent alarm, auto-start dive mode, and a power reserve indicator paired with a red countdown scale on the blue unidirectional rotating bezel. A buckle secures the blue strap, and the watch features eco-drive technology powered by any light, so it never needs a battery.
