Tissot T-Sport Seaster 1000 Chronograph Diver's Quartz T120.417.11.091.01 T1204171109101 300M Men's Watch The Tissot T-Sport Seastar 1000 is submersible up to 300 meters; that’s roughly a thousand feet. Tissot has combined professional diving elements from the Swiss watchmaking tradition, making it a watch not just for them who love diving. The chronograph is equally functional on land and in water, however; it’s recommended that you start it immediately before diving and stop after you are out from water.
