The Tag Heuer Connected Caliber E4 comes in two variants, namely 42 mm and 45 mm models, respectively. Despite the size, there are several design features that set the two models apart from each other.
Tag Heuer has pioneered the luxury smartwatch brand with the Carrera Connected, as well as several other smartwatch models, but this latest pair of models doesn’t have much in common with its predecessors.
The 45mm model comes with different options in terms of its casing, and straps to cater to the design choices of different segments of the smartwatch market.
On the other hand, the 42 mm model comes in a single version with a casing made of polished steel, although several strap options are available.
The Connected Caliber E4 45 mm smartwatch is equipped with a heart rate sensor, NFC for mobile payments, altimeter, compass and GPS. The 430 mAh battery can offer the wearable a full day of use, including up to five hours of tracking.
The processor, software and other hardware features are the same for the 42 mm model, but the battery is smaller at 330 mAh.
Prices for the Tag Heuer Connected Caliber E4 range from $1,800 to $2,500, with the titanium-coated 45mm model being the most expensive of all.
