TAG Heuer Ditches Google Wear OS For iPhone Users - Connected Calibre E5 Review (2025)

Picture this: a high-end smartwatch from a legendary luxury brand that's finally ditching its old tech partner to cozy up perfectly with your iPhone. TAG Heuer is shaking things up with their latest creation, and it's got everyone talking! But here's where it gets controversial – is this a bold leap forward or just another workaround in the endless Apple vs. Android saga? Let's dive in and unpack the details, step by step, so even if you're new to smartwatches, you'll feel right at home.

For nearly a decade, TAG Heuer has relied on Google's Wear OS as the brains behind its Connected series of smartwatches. You can check out the specs and history of those earlier models if you're curious about how they've evolved. But now, with the brand-new Connected Calibre E5, they're waving goodbye to Wear OS – that's the operating system Google developed for smartwatches, which lets them connect to phones and run apps smoothly. Instead, TAG Heuer has crafted its very own custom interface called TAG Heuer OS. This isn't just a rebrand; it's designed from the ground up in-house for what they call a 'fluid, intuitive experience' that makes navigating the watch feel effortless. And this is the part most people miss – even though it's built on Android (the same foundation as many other smartwatches), these tweaks mean it now works seamlessly with iOS devices, like iPhones.

Why the big switch? Well, if you've ever tried pairing a Wear OS watch with an iPhone, you know it can be a frustrating ordeal. Wear OS watches do connect, but the experience often falls short of ideal. For instance, iOS has historically blocked non-Apple devices from key features, such as displaying iPhone notifications when the phone's screen is locked or enabling voice calls over Bluetooth through the watch. It's like being invited to a party but not allowed to dance – you can show up, but the fun is limited. That said, things might improve soon thanks to a new EU regulation pushing Apple to open up its ecosystem for better interoperability with third-party wearables. Imagine being able to use any smartwatch with your iPhone without those annoying restrictions – it's a game-changer for choice and innovation!

On the flip side, Google hasn't exactly been helping matters. They've essentially abandoned Wear OS support for iPhones, with their app on the iOS App Store gathering dust for over two years without updates. Is this Google's way of throwing in the towel, or has Apple's walled garden simply overwhelmed them? The truth is murky, and it sparks debate: Should tech giants like Google fight harder for cross-platform harmony, or is it smarter to focus on their own ecosystems? TAG Heuer isn't waiting around – they're going the extra mile to ensure their watch shines on iPhones. The Calibre E5 has earned Apple's prestigious 'Made for iPhone' certification, which basically guarantees smooth notification flows and better integration. Think of it as a VIP pass that unlocks the full potential of your iPhone-watch duo, without the glitches.

Now, let's talk battery life, because that's always a hot topic with smartwatches. TAG Heuer promises up to two days of use on the Calibre E5, but they admit it's a conservative estimate that doesn't even factor in perks like the always-on display. For beginners, this means you might get more juice out of it in real-world use, depending on how you tweak settings – a nice surprise if you're used to watches dying after a day.

Under the hood, the watch packs Qualcomm's Snapdragon Wear 5100 Plus processor. Sure, it's not the latest and greatest (some might call it a bit outdated), but it's a solid upgrade from the Wear 4100 chip in the previous model from over three years ago. The Calibre E5 comes in 40mm and 45mm sizes, with minimal visual tweaks from before, but TAG Heuer has overhauled the algorithms for improved efficiency – think faster performance and smarter power management. And for those with specific interests, there are special editions collaborating with New Balance for fitness enthusiasts and Golf for the links lovers, adding a touch of personalization.

Pricing starts at $1,600 for the 40mm version, jumping to $1,700 for the 45mm. If you opt for premium materials or styles, expect to pay more, with the special editions hitting $2,400. It's an investment, no doubt, but for luxury watch fans, it's about that blend of tradition and tech.

So, what do you think? Is TAG Heuer's move to a custom OS a brilliant strategy to bridge the iPhone gap, or does it highlight deeper issues in the smartwatch world? Do you believe Google should revive Wear OS for iPhones, or is Apple's dominance here to stay? Share your thoughts in the comments – I'd love to hear if you're team Apple, team Android, or somewhere in between!
