Garmin Epix Pro vs Epix Gen 2: Which AMOLED Sports Watch Should You Buy?

Introduction

Garmin now sells two very similar premium AMOLED sports watches: the newer Epix Pro and the original Epix Gen 2. Both deliver the same core experience, including top-notch GPS accuracy, strong sports tracking, and Garmin’s best training analysis on a bright AMOLED screen. The differences come down to case sizes, an LED flashlight, an upgraded heart rate sensor, battery life on the larger model, and a handful of software extras that are expected to roll back to the older watch over time. Here is how they compare and which one makes the smarter purchase.

Price and Value

Both are very expensive watches, and that does not change much in the short term. When a new Garmin watch launches, the previous model usually drops in price, though that shift may come faster at third-party retailers than buying directly from Garmin. If you can pick up the Epix Gen 2 for less, it remains the better-value option for most buyers.

Design and Hardware Differences

The biggest hardware change is case sizing. The Epix Pro comes in three sizes (42mm, 47mm, and 51mm), while the Epix Gen 2 is only available in a 47mm case. The 42mm and 47mm Epix Pro models feel very similar in character to the Gen 2, while the 51mm version brings a bigger case and a larger screen comparable to Garmin’s largest flagship watches.

The Epix Pro also adds an LED flashlight built into the top of the case, something that cannot be added to the Gen 2. It is bright enough to be a genuinely useful light source, especially for runners who train alone at night, and it sits completely unobtrusively when not in use. Straps, waterproofing, buttons, touchscreen behavior, and the mix of touch and button interaction remain essentially the same across both watches.

Heart Rate Sensor Upgrades

The Epix Pro ships with an upgraded optical heart rate sensor promising improved exercise tracking. In extended testing, the Epix Gen 2 performed like most optical sensors: largely fine, but with occasional errors, sometimes sustained ones, that skewed run analysis and training metrics. The Epix Pro has been noticeably more reliable, with only a handful of short-lived errors across a month of testing.

That said, the improvement still does not remove the need for a chest strap if you train seriously by heart rate. Readings can still jump at the start of a run or lag behind a strap, so pairing a strap remains the recommendation for either watch. If both watches end up paired to a strap anyway, the sensor advantage matters less.

Software Features on the Epix Pro

Several software features are currently unique to the Epix Pro, including improved mapping with relief shading, weather map overlays, and a redshift mode that turns the entire screen red for night use and is less disruptive when checking the time in bed.

There are also new training metrics: Hill Score, which gauges whether your training has prepared you for hilly courses, and Endurance Score, which uses VO2 max and historical data to estimate your ability to sustain performance over long efforts. The important caveat is that Garmin is expected to roll these features back to the Epix Gen 2 over time, so they are not permanent exclusives.

Run Tracking and GPS Accuracy

In real-world testing, including marathons and everyday training, run tracking on the two watches is near identical. Both were tested in their top multiband multi-frequency GPS modes, and accuracy was very good on both, with no meaningful improvement seen on the Epix Pro. Day-to-day smartwatch use, menu navigation, and the overall tracking experience feel the same across both watches, with readiness and training analysis already present on the older model.

For most runners, the Epix Pro’s extras do not dramatically change the experience. Unless you run a lot at night and genuinely need the flashlight, the older watch covers the same ground.

Battery Life

Battery life is where the 51mm Epix Pro stands apart. The 47mm Epix Pro and the Epix Gen 2 last roughly five days with an always-on screen and daily running, essentially the same as each other. The 51mm Epix Pro doubles that, lasting around 10 days in the same conditions, and even longer with raise-to-wake enabled instead of an always-on display.

For an AMOLED sports watch, that is a striking result and puts it close to the endurance of Garmin’s solar flagship range. The trade-off is a bigger, more expensive watch that is less comfortable to wear all day on thinner wrists. If you are happy charging every five days, the Gen 2 experience is still excellent; if you want to halve your charging frequency, the big Pro is the one that earns its price.

Buying Advice

If you already own an Epix Gen 2, there is little reason to upgrade. The new software features will arrive on your watch anyway, and the flashlight and heart rate improvements are nice but unlikely to be game changers. If you are choosing between the two from scratch, the Epix Gen 2 is the cheaper starter pick, and it is worth seeking out a sapphire model to get multiband GPS, which is genuinely impressive. The exception is the 51mm Epix Pro: doubling the battery life of an AMOLED watch is a meaningful upgrade, and if you are happy to spend more and wear a larger watch, that model is currently the best AMOLED sports watch available. It is also worth noting that AMOLED battery life is improving quickly, so existing Epix Gen 2 owners may be better off waiting to see what future Epix generations deliver.

Conclusion

These are very similar watches with very similar everyday performance. The Epix Gen 2 remains a great watch and the smarter value pick, especially at a discount, while the Epix Pro earns its place mainly for the 51mm model’s exceptional battery life and, for some, the built-in flashlight. Choose based on whether those specific upgrades are worth the premium to you.
