TAG Heuer, the well-known Swiss manufacturer of luxury watches, has just launched the new model of the Connected range: the TAG Heuer Connected Calibre E4. It is a device with the most premium finishes that comes in two versions, one of 42 millimeters and one of 45 millimeters, each with a larger screen.

They differ not only in size but also in some aspects of the design that we will review later. In any case, both have the Snapdragon Wear 4100+ (the latest from Qualcomm for smartwatches) and WearOS 2 as the operating system. Having made the introductions, let’s get to know them better.

WearOS with a luxury finish

TAG Heuer Connected Calibre E4

Let’s start by talking about the 42-millimeter model. This one has a more casual finish, with a thinner case and a slightly curved display on the sides. It is in that curvature we find, precisely, the minute hand. The case is made of polished steel with fine brushing, the crown of silver steel, and steel pushers. The back, meanwhile, is made of steel. All this with a water resistance of 50 meters.

The 45-millimeter model, on the other hand, has a sportier finish, with the minute hand engraved on the bezel. Unlike the 42-millimeter version, this one has two types of cases: polished steel or titanium, depending on the version. Below you can find all of them in detail. The display, meanwhile, is completely flat and is protected by a sapphire crystal.

Speaking of specifications, the 42-millimeter Calibre E4 features a 1.28-inch OLED display with 416 x 416 pixels of resolution. The 45-millimeter one has a larger 1.39-inch panel with 454 x 454 pixels of resolution. In both cases, there are 326 pixels per inch and the possibility of using different dials with contextual information.

Inside we find the Snapdragon 4100+ processor, the latest from Qualcomm for smartwatches, and an integrated GNSS GPS chip (compatible with the main satellite constellations). The operating system is WearOS 2 (upgradeable to WearOS 3) and the battery is 330 or 430 mAh, depending on the model. In both models, the battery will last a day, although it will depend on whether the GPS is used or if the user is involved in sports. Charging is done using vertical magnetized support.

And speaking of sport, TAG Heuer allows access to TAG Heuer Sports, which offers guided exercise routines and supports running, cycling, golf, and walking. One of the main new features are guided workouts, with preset routines, and the ability to customize the function with your routines.
