The Q Founder is the biggest of the trio with its 47mm diameter case, the rest are smaller at 45mm. All of them support Bluetooth 4.1 LE and Wi-Fi 802.11n connectivity. Under the circular display ticks the Qualcomm Snapdragon 2100 chipset with 4GB of storage.
Because of its larger size, the Q Founder has a 400mAh battery, while the others have 360mAh ones. Charging happens via a cradle placed on the back of the watch which latches on with a magnet.
Pricing of the Fossil smartwatches is in the $275-$295/299-319 range depending on the model and wristband. You can chose between a two-tone stainless steel band or brown or black leather bands.
