TAG Heuer’s new smartwatches abandon Wear OS to become an alternative to the Apple Watch thanks to “Made for iPhone” billing


  • TAG Heuer offers a new smart watch with Made for iPhone certification
  • The Connected Caliber E5 sees TAG Heuer abandon Wear OS
  • It offers a range of health features and better iOS integration

TAG Heuer’s best smartwatches have stuck with Wear OS over the years, but that’s all changing with the company’s latest effort. With the release of the Connected Caliber E5, TAG Heuer has focused on iOS connectivity, with Made for iPhone certification accompanying the watch.

The device is the successor to the Connected Caliber E4, which impressed us in our test. But in ditching Wear OS, TAG Heuer has charted its latest smartwatch down a new path, equipping the Connected Caliber E5 with its own custom operating system, aptly dubbed TAG Heuer OS. This comes with a new user interface, new animations and improved menus.
