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."
Oris Aquis Depth Gauge
Among dive watches, the Aquis Depth Gauge is unique in how it measures depth. "There's a specially milled channel in the crystal," explains Oris' North American CEO, V.J. Geronimo. "So as you descend, water pushes the gauge along." The sporty black rubber strap makes this comfortable to wear at the beach. [$3,500; oris.ch]
