From MotoGP to Le Tour De France, Tissot is the official timekeeper of many high-profile sports events involving land vehicles. But the Swiss watchmaker is equally invested into what happens below sea level. At least that's what the Tissot Seastar 1000 Quartz Chrono Aquatic Elegance seems all about. 

A long time favourite amongst brand loyalists, the Seastar is now available in chronograph form as Tissot attempts to widen the appeal of its 45.5mm diving watch. Its stainless steel case contains a Chronograph Quartz movement which will keep the Luminescent hands ticking under pressure - 30 bar of pressure to be precise, which is what you'll get 1,000 feet (300m) beneath the surface of the sea. Not that the average human being would dare explore those depths.
