You need a watch that can keep up with your summer, from the office to the bar to the beach for a swim. These five waterproof watches are built to handle offshore nautical races and military special-ops raids – a little sand isn't going to stop them. "Just as you need different types of shoes for summer, you should have different types of watches," says Alpina president Ralph Simons. "A leather strap isn't as comfortable on a hot day."
The bold and dramatic design of Tissot's T-Race is inspired by motorcycle racing. The big dial tells you the time, while the three small subdials can act like a stopwatch – tracking the number of seconds, minutes, and hours that have elapsed. It's a cool-looking watch for timing workouts or steaks on the grill. [$650; tissot.ch]
