The Tissot Seastar 1000 40mm dive watch presents a striking turquoise dial in a 316L stainless steel case and bracelet, powered by a Swiss quartz movement. A double-antireflective sapphire crystal shields the dial, a unidirectional rotating dive bezel measures immersion time, and a screw-down crown enables water resistance to 300 meters. A date window and butterfly clasp round out this capable everyday diver.
