Amazon offers the Casio Unisex OmniSync Sports Bluetooth-Enabled Smartwatch, model no. STB-1000-1CF, for $49.99 with free 1-day shipping. That's tied with last week's mention as the lowest total price we've seen. (It's 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. Deal ends December 23 at 3 pm ET.
This order will arrive by Christmas.
