Rugged and responsive, this Connected Modular 45 smartwatch from TAG Heuer combines a 45mm titanium grade 5 case topped by a sapphire crystal with seamless connectivity through Bluetooth to mobile devices. The case has fully removable, customizable lugs to change straps and clasps as convenient. Advanced in more ways than style, this smartwatch allows the wearer to switch between the digital Android/iOS compatible unit to a custom traditional analog automatic movement (sold separately) by swapping the main module. Functions include a haptic engine, tilt detection, gyroscope, proximity sensor at 6 o'clock and a microphone at 3 o'clock, and water-resistance to 50 meters. The smartwatch includes a charging puck, micro USB cable and wall plug.
