Amazon offers the Casio Men's OmniSync Sports Bluetooth-Enabled Smartwatch, model no. STB-1000-1CF, for $49.99 with free shipping. That's tied with our December mention as the lowest total price we've seen. (It's also a current low by $10.) It's compatible with most Bluetooth-enabled smartphones - including the iPhone - and features an LED-backlit display, four daily alarms, 120-lap memory, phone finder capability, and water resistance up to 330 feet.
