Tissot Seastar 2000 Professional vs Tissot Seastar 1000 40mm Powermatic 80

Both are automatic Tissot divers with sapphire crystals, but they target different wrists and budgets of use. The Seastar 2000 Professional is the tougher tool watch: 600m water resistance, a ceramic bezel insert, a domed sapphire crystal and a display case back, in a 44mm case. The Seastar 1000 40mm Powermatic 80 is the easier daily wear: a smaller 40mm case, a steel bracelet and the 80-hour Powermatic 80 movement, rated to 300m. Owners of the 2000 praise its looks, timekeeping and bright lume, but some find it large and the rubber strap short. Buy the 2000 for serious dive capability and presence; buy the 40mm for a comfortable, versatile everyday diver.

• Choose the Seastar 2000 Professional if you want maximum water resistance, a ceramic bezel and a display case back, and your wrist suits a 44mm case.
• Choose the Seastar 1000 40mm if you want a smaller, lighter everyday diver on a steel bracelet with an 80-hour power reserve.
