The TAG Heuer Connected Calibre E4 Golf Edition promises serious golf features in a refined 42mm case
Golf wearables typically fall neatly into two categories: purpose-built devices with deep performance metrics and sport-forward designs, or premium smartwatches and hybrids offering lifestyle appeal but only basic on-course utility. Very few attempt to combine the two—and even fewer do so convincingly.
TAG Heuer first entered this space in 2020 with the Connected Golf Edition, a 45mm smartwatch that brought together shot tracking, hazard mapping, and a sleek titanium build more commonly seen in traditional timepieces. It marked one of the first serious efforts to merge golf-specific technology with the craftsmanship and design language expected of a Swiss luxury watchmaker.
The newer Calibre E4 Golf Edition 42mm refines that original concept. We tested the device—now boasting a smaller case, enhanced shot tracking, and elevated wearability—over a round of golf to see if it was up to par.
Here are five things you need to know.
A seamless golf companion
The standout feature of the E4 Golf Edition is its Full Shot Tracking—a fully automated system that detects shots from tee to green without the need for tapping, tagging, or wrist fiddling. Every stroke, including putts, is logged by internal motion sensors. Better yet, the system assigns shots to clubs based on evolving performance data, allowing the watch to personalise club recommendations over time.
This turns the E4 into something akin to a digital caddie. You glance at your wrist and see distances to hazards, a 2D visual of the hole, and a club suggestion—without any manual input. It covers over 40,000 courses worldwide, with quick load times and smooth transitions between holes. The result is a round of golf that feels uninterrupted and informed.
Compact & comfortable
At 42mm, the E4 is a shift away from the larger, more imposing designs of prior Connected models. The size reduction, coupled with a Grade 2 sandblasted titanium case, makes this the lightest Connected watch TAG Heuer has produced—and the difference is noticeable.
Whether you’re playing 18 holes or wearing it all day, the watch stays balanced and unobtrusive. It hugs the wrist without digging in, and crucially, doesn’t shift mid-swing. The compact build also broadens its appeal, making it more suitable for golfers with smaller wrists and giving it true unisex wearability.
Play-ready
The E4’s interface is purpose-built for real play, not just showroom demos. The 1.28” OLED display is bright, high-contrast, and legible even in direct sunlight. A combination of touchscreen and rotating crown navigation means you can scroll through hole views, hazard maps, or club histories—even with a glove on.
The software UI avoids clutter. Hazards are marked clearly, distances are immediate, and each hole view transitions smoothly as you move through the course. You’re never more than a single action away from the information you need—making it a watch that complements play rather than interrupting it.
Smart features without the clutter
Where many golf watches overwhelm users with advanced (and often unused) metrics, the E4 Golf Edition trims the fat. It does not include slope-adjusted distances, wind data, or green-contour maps, which are standard in some competitors. But that’s a conscious tradeoff.
Instead, you get fast, accurate GPS, dependable shot tracking, and intelligent club suggestions—core features that work without the need to babysit the interface. For most players, this translates to a smoother round. There’s enough intelligence to improve your game, but not so much complexity that it gets in the way.
And when you want to review your performance later, the TAG Heuer Golf app offers a clean post-round breakdown synced from your watch, making analysis intuitive and digestible.
A Daily Driver
While the Calibre E4 Golf Edition wears like a smartwatch—complete with touchscreen, sensors, and a slightly elevated profile—TAG Heuer has embedded it with the kind of design language that makes it unmistakably theirs.
The sandblasted Grade 2 titanium case, the angled lugs, and the ceramic bezel etched with 1–18 hole markers all nod to the brand’s chronograph heritage. The oversized crown and flanking pushers mirror mechanical sports models like the Carrera, while the folding clasp with engraved TAG Heuer shield is taken directly from their mechanical lineup. Even the digital watch faces echo the layouts of classic TAG Heuer dials, maintaining a visual throughline from analog to connected.
Functionally, the watch runs on the Qualcomm Snapdragon 4100+ and Wear OS by Google, supporting notifications, contactless payments, calendar sync, activity tracking, and music control. Sensors include heart rate, compass, barometer, accelerometer, microphone, and NFC.
Battery life covers a full day of general use or approximately five hours of continuous GPS tracking—enough for 18 holes. A full charge takes around 90 minutes. The result is a device that functions like a premium connected watch, but presents itself with the familiar detailing and materials of a TAG Heuer timepiece.
