Tag Heuer is taking a risk with its new Connected Calibre E5 smartwatch by leaving Google and Wear OS behind, and going it alone with its own Tag Heuer OS software.
While at first it may seem like an odd decision to say goodbye to Wear OS, the more you understand the reasons why, the more it makes sense. The Calibre E5 moves on from the old way of doing things, and after spending some time with the replica TAG Heuer watches UK and software, it has me really intrigued.
Why Tag Heuer OS?
Tag Heuer OS is the first smartwatch operating system to be Made for iPhone (MFI) certified, which is key to understanding why Tag Heuer hasn’t used Wear OS for the new watch. Don’t worry Android phone owners, the Calibre E5 still works with your phone, but according to Tag Heuer a massive 70% of people who buy the brand’s perfect copy TAG Heuer watches use an iPhone.
The decision took me by surprise. Tag Heuer was one of the first brands to embrace Wear OS 3, when Google allowed the connecting app to be customized, providing smartwatch makers a way to personalize the experience. However, since then, Google has made Wear OS less open, including special partnerships with Samsung for Wear OS 5, and naturally focusing on its own Pixel Watch smartwatch, while also putting less emphasis on iOS over time.
When 70% of your audience uses an iPhone, this causes immediate problems, and as a relatively small smartwatch manufacturer, Tag Heuer took it as a sign to try something new. A team of 60 in-house engineers have worked on the Calibre E5 and its software, leaning on experience from LVMH stablemate Louis Vuitton’s recent Tambor Horizon Light Up swiss fake TAG Heuer watches, to create Tag Heuer OS. The MFI certification makes fast, reliable pairing possible with iOS, and the ability to integrate Siri and features like taking calls. While the focus is on iOS, Android owners won’t miss out on any features.
What’s Tag Heuer OS like to use?
It’s different, in a good way
Anyone used to Wear OS or Watch OS will immediately notice how swipes on the touchscreen have less priority in Tag Heuer OS, and the two side buttons and crown are far more integral to navigating the software. The top button opens a menu, which is then navigated by touch or by rotating the crown, while the lower button opens quick settings.
Swiping up on the screen shows your notifications, and a downward swipe shows a series of widgets. At launch, these widgets will include fitness and health data along with the weather, and other widgets will be added over time. A long press of the crown brings up the clone TAG Heuer watches for sale face options, which include a huge range of faces inspired by Tag Heuer watches from the Formula One, Aquaracer, and Carrera watches.
What about the rest of the tech?
Longer battery life
Tag Heuer’s control over the software enables it to improve efficiency and lengthen battery life compared to what’s normally possible from a Wear OS smartwatch. Tag Heuer expects two days from a single charge for the 45mm version, and around a day-and-a-half on the 40mm. There’s also a Low Power mode which adds about another day’s battery life.
Other key specification details include the Qualcomm Snapdragon 5100+ processor, a 1.39-inch AMOLED screen on the 45mm version and a 1.20-inch AMOLED on the 40mm watch, dual-band GPS, Bluetooth 5.3, Wi-Fi, and 50 meters of water resistance.
Prices vary between £1,350 to £2,050, or around $1,800 to $2,750, and although this is obviously more expensive than the Galaxy Watch 8 and even the titanium Apple Watch Series 11, it’s the most affordable TAG Heuer , and the brand sees it as the ideal entry point into Tag Heuer ownership. The high quality replica Tag Heuer Connected Calibre E5 watches will be available to buy from October 2025.
