If I’m splurging on a Tag Heuer watch, smart or otherwise, I want it to feel pretty special on my wrist. Its Connected Calibre E4 42mm costs $1,800 and doesn’t do anything an Apple Watch or Galaxy Watch can’t do. In fact, it does less, so I absolutely better feel something amazing when it’s on my wrist. Over the last 10 days, I’ve found out what it’s like to wear.


Before anything else, you should understand Tag Heuer’s new smartwatch range. There are two models, the 42mm Connected Calibre E4 you see in our photos and that I’m reviewing here, plus a 45mm version with the same technology but a slightly different design. Following the single 45mm Connected Calibre E3, the choice of 42mm and 45mm models in the Calibre E4 range is very welcome, and slimming the case down to 13.9mm makes it more wearable. However, there’s no change in materials used — it’s stainless steel with a ceramic bezel — and there’s no titanium option for the E4 either.

I’ve yet to wear the 45mm model, but based on previous experience and wearing the 42mm version this time, I’m confident that, again, the smaller smartwatch is the one that will suit most people. The smaller 1.28-inch screen is just right, it fits under shirt cuffs, the curved sapphire crystal over it looks glorious, and the streamlined pushers and simple crown give it a seriously sophisticated look. For reference, it’s on my 6.5-inch wrist in the photos.

I showed it to a friend who doesn’t like the size and weight of most current smartwatches. He liked this one a lot, and said the shape, size, and design was the most appealing he’d seen. It’s exactly the kind of reaction you want. With the right watch face, it has the classic Tag Heuer look too, but is never over the top, or worse, cheap-looking. The super-sharp, very bright 416 x 416 pixel screen definitively makes the most of the various Tag Heuer watch faces.

The 42mm Connected Calibre E4 has a polished stainless steel case and is attached to either a steel, rubber, or leather strap. The rubber one on my review model is comfortable but can get a little sweaty, and it hasn’t got much “give” either, so I’ve had to wear it quite tightly or it tends to not sit squarely on my wrist. I love the folding clasp though, which is easily adjusted and really does look cool. It’s such a recognizable design and helps identify the smartwatch as one made by Tag Heuer. If you don’t like the strap, or want a few alternatives, Tag Heuer sells a variety of compatible straps for the Calibre E4 starting at $200.

The pushers have a very mechanical feel to them, adding a quality feel, and the rotating crown helps you navigate through the watch’s menus with speed and precision. The bezel incorporates hour markings and the Tag Heuer insignia, and because it’s set under the crystal, it doesn’t affect touchscreen use.

The Connected Calibre E4 is luxurious, elegant, and expertly built, with an awareness of what makes a good smartwatch without losing sight of what makes a Tag Heuer watch desirable. But did I feel different? The Tag Heuer name has cachet it’s supremely comfortable due to its spot-on size, and the sapphire crystal is warm and inviting to touch. I love the way it looks, and I like the way it makes me feel from the moment I close that iconic clasp on the strap.
