LightInTheBox offers the Ezon Men's L008 Digital Sport Watch in Black for $17.99 with free shipping. (Antique China 2009 via eBay has it for the same.) That's $7 off and the best price we could find. It features a stopwatch function, timer, two sets of alarms, silicone case and band, and water resistance to 100 feet.

Note: This item ships from China and may take two to five weeks to arrive. Uncheck "Add Shipping Insurance to your order" during checkout to remove the 49-cent fee.
