Sport-watch maker Reactor has debuted its Graviton 2 tide watch, catering to boaters and anglers. The watch comes preloaded with tide information from 275 of the top North and Central American fishing and boating destinations. The Graviton 2 also displays tide height, sunrise/sunset times and moon-phase data. Tides for other areas may be added with a plus- or minus-180-minute offset feature. Turn off tide functionality for a clean analog-watch look. Depth rated to 660 feet, the watch comes in three bracelet styles and costs $500 to $575. Call 800-291-6600, or visit www.reactorwatch.com.
