Design & Hardware:
At first glance, the Garmin Tactix 8 AMOLED and Solar Editions are virtually indistinguishable. Both models share an identical case size, durable titanium bezel, fiber-reinforced polymer housing, and a sapphire lens that screams premium. If you’re coming from the Tactix 7, you’ll immediately notice that the Tactix 8 has a slightly larger footprint, making room for its more advanced display while still feeling balanced on the wrist. Despite their larger stature, neither watch feels bulky, thanks to Garmin’s refined engineering.
The tactile experience has also improved dramatically. The buttons are now more satisfying to press, with better feedback and spacing—an upgrade that becomes immediately noticeable during activities or while wearing gloves. Garmin clearly listened to feedback from previous models, as the button feel on the Tactix 8 delivers a modern smartwatch vibe while maintaining the rugged edge the Tactix series is known for.
Another subtle but welcome enhancement is the improved haptics. The vibration motor now feels tighter and more responsive. Compared to the Tactix 7’s dull pager-like vibration, the Tactix 8 feels polished—closer to what you’d expect from a premium watch in 2025. Whether you’re receiving alerts or alarms, the new haptic system delivers a more refined notification experience.
Physically, both the AMOLED and Solar models are identical. Weight, button layout, and even the rear sensors are the same. The AMOLED model, however, might feel slightly “flashier” because of the vibrant display that catches the eye, while the Solar Edition stays subtle and utilitarian. Both watches feature built-in LED flashlights on the top housing, complete with adjustable brightness and green light modes—super useful for early risers, tactical use, or nighttime convenience.
Garmin has retained the military-grade durability in both models. They’re rated to MIL-STD-810 standards and are water-rated to 10 ATM. Whether you’re trail-running, diving, or parachuting out of a plane (seriously), these watches can take it all. The buttons and casing are designed to survive the extremes, and that hasn’t changed.
In terms of wrist feel, comfort remains excellent. The silicone strap provided is breathable, durable, and fits well on most wrist sizes without irritation. You can also swap bands easily thanks to Garmin’s quick-fit mechanism. The watches sit flush on the wrist and don’t shift around during workouts, hiking, or daily wear.
From a hardware perspective, you’re getting the same top-tier smartwatch regardless of which display tech you choose. There are no differences in materials, features, or sensors—the real divergence begins once the display lights up.
Navigation & Software Changes:
Garmin has made meaningful improvements to the user interface and system navigation with the Tactix 8 series, and both the AMOLED and Solar Editions benefit from these enhancements. The layout is cleaner, snappier, and more intuitive compared to previous models like the Tactix 7, which had a more utilitarian, button-heavy feel. Navigating through menus is now faster, with smoother transitions and improved animations—especially on the AMOLED version where the vibrant screen brings UI elements to life.
One of the most noticeable upgrades is the restructured activity categorization. Instead of endless scrolling, Garmin now groups activities into four clear sections, making it significantly easier to locate what you’re looking for. Whether you’re launching a run, checking dive settings, or opening maps, the organization is faster and more efficient.
The AMOLED model stands out visually here. Icons and UI elements are more defined, colorful, and readable. That said, the Solar model still performs just as well functionally—it just lacks the eye-popping clarity of the AMOLED. Responsiveness is excellent on both models, with almost zero lag when switching screens or interacting with widgets.
Another thoughtful addition is the improved gesture support. On the AMOLED model, users can enable wrist-raise to wake the screen—something that was previously unavailable out of the box. This small change significantly boosts day-to-day usability without draining the battery too aggressively (though it still has an impact).
While Garmin’s proprietary OS isn’t flashy, it’s optimized for efficiency and works reliably under pressure. Both models support the latest features like real-time stamina tracking, performance condition assessments, and customizable widgets. You also get access to offline mapping, weather overlays, and detailed route planning tools that are particularly useful for athletes, adventurers, and military personnel.
In short, the navigation feels more modern, better organized, and highly responsive across both models—but the AMOLED display gives the entire interface an unmistakable polish that’s hard to ignore.
Music & Storage Updates:
Both the Tactix 8 AMOLED and Solar Editions come with 32GB of internal storage, which is more than enough for offline maps, apps, and up to 2,000 songs. Whether you’re syncing playlists from Spotify, Amazon Music, or Deezer, storage isn’t going to be a limitation on either model. This is especially handy for users who prefer to leave their phones behind during workouts or trail runs.
File management is simple through the Garmin Express desktop app, which allows for easy uploads of music, podcasts, and audiobooks. Once synced, tracks can be accessed directly from the watch and organized into playlists. You can also sideload .mp3 files manually if you prefer full control over your audio files.
Music Playback and Controls
In terms of playback, both watches support Bluetooth headphone connectivity, with stable pairing and minimal delay. Playback controls are accessible through widgets and the quick-access menu, giving users the ability to skip tracks, adjust volume, or pause on the go. Audio quality and range are excellent, provided you’re using quality earbuds or bone-conduction headphones.
AMOLED vs. Solar for Music Features
There are no feature differences in the music department between the AMOLED and Solar models. However, the AMOLED version’s display makes navigating music playlists and album art slightly more enjoyable. Album covers and app icons appear clearer and more vibrant, giving the interface a more premium look. Still, in practice, this doesn’t drastically affect usability—especially if you’re the type to start your playlist and leave it running in the background during workouts.
In short, music storage and playback capabilities are identical across both editions, with only minor visual perks favoring the AMOLED. For music lovers who value display aesthetics, AMOLED is a treat. For everyone else, both deliver an excellent standalone music experience.

Battery Life:
Battery life is the defining difference between the Garmin Tactix 8 AMOLED and Solar Editions—and it’s not even close. While both models use the same operating system and hardware, the display technology changes everything when it comes to endurance.
The Tactix 8 Solar Edition is the undisputed king of longevity. Thanks to its Power Sapphire lens and solar harvesting capabilities, this model sips power in ways the AMOLED version simply can’t. In standard smartwatch mode, the Solar can last up to 40 days with optimal sunlight exposure, and around 20-25 days even in average conditions. That’s more than enough for weeks of training, travel, or military field use without ever thinking about a charger.
In contrast, the AMOLED Edition delivers a brighter and more visually appealing experience, but at a cost. With always-on display off and moderate use, you can expect 8–12 days of battery life—less if you frequently enable gesture wake or do multiple GPS workouts. In testing, the AMOLED model dropped 7% in under a day without heavy usage, just from daily wear and glancing at the display. Enabling always-on display further reduces endurance, potentially requiring a recharge every 3–4 days depending on use.
Both models benefit from Garmin’s battery saver modes, which intelligently scale back features to extend life further. But only the Solar can realistically run for weeks at a time without reaching for the charger.
In summary, if long-lasting battery life is your top priority—whether for field work, expedition travel, or just peace of mind—the Solar Edition wins hands-down. The AMOLED looks amazing, but you’ll be charging it far more frequently.

Both versions of the Garmin Tactix 8—AMOLED and Solar—come equipped with Garmin’s latest Elevate™ Gen 5 optical heart rate sensor, bringing precision and expanded functionality for a range of health and wellness metrics. Whether you’re monitoring your resting heart rate or tracking stress throughout the day, these watches are packed with comprehensive wellness features.
24/7 Heart Rate Monitoring
Continuous heart rate tracking works flawlessly on both models. The readings are consistent and accurate, especially during daily wear and non-strenuous activities. Users can view live heart rate, resting averages, and abnormal heart rate alerts in real-time. When compared to chest straps, both Tactix 8 models perform admirably, with only minor variances during high-intensity spikes—an expected limitation of optical sensors in general.
The AMOLED model benefits from a clearer visual presentation of heart rate graphs and color-coded zones, making it easier to interpret your data at a glance. However, both watches track the exact same metrics and use the same sensors, so the data itself remains identical.
SpO2 and Respiration Tracking
Blood oxygen saturation (SpO2) tracking is available both on-demand and during sleep. You can also enable continuous monitoring, though it significantly impacts battery life—especially on the AMOLED model. Respiration rate tracking is integrated into daily overviews and is useful for understanding stress or recovery patterns.
Stress Tracking & Body Battery
Garmin’s Body Battery feature remains one of the best wellness tools for gauging daily energy levels. It combines heart rate variability, stress, and sleep quality to give users a live “battery percentage” representing how ready their body is for exertion. Both AMOLED and Solar versions use this feature identically, and it’s highly useful for planning workouts or rest days.
Stress tracking is also real-time and uses heart rate variability to detect how much physiological stress you’re under. You can view trends by hour, day, or week, and the data integrates cleanly into Garmin Connect.
Sleep Tracking Accuracy
Sleep tracking has improved over the years and now includes Sleep Score, sleep stage breakdown, and integration with recovery metrics. While both models deliver excellent sleep data, the AMOLED version gives you more aesthetically detailed sleep graphs on the watch itself. Still, for those who mostly view sleep data in Garmin Connect, this becomes a non-issue.
Temperature Sensor & HRV Status
Garmin now includes a skin temperature sensor and HRV Status tracking—vital for detecting early signs of illness or overtraining. These features are consistent across both models. HRV status is particularly helpful for athletes managing training load or stress levels during competition seasons.
In summary, both the Tactix 8 AMOLED and Solar deliver elite-level health tracking, with no feature disparity in this department. The only difference lies in how the information is presented—more vibrant and detailed on the AMOLED, but functionally identical across both.
Activity & Fitness Tracking:

Auto-detection for activities like walking, running, biking, and swimming works reliably on both models. The watch will automatically log the workout if you forget to start it manually—a welcome feature that saves data and effort.
Sports Modes & Multisport Features
With support for over 80+ sports and activities, the Tactix 8 lineup excels in versatility. Whether you’re hitting the gym, running a triathlon, doing CrossFit, or engaging in tactical drills, the watch is ready. Multisport tracking is seamless, especially for triathletes who need accurate transitions between swim-bike-run without stopping the timer.
GPS Accuracy & Outdoor Performance
Both versions include multi-band GNSS support, which means significantly enhanced GPS accuracy—even in challenging environments like dense forests or urban canyons. Garmin’s real-time satellite acquisition is fast and reliable, making route tracking and breadcrumb navigation impressively accurate. This is essential for mountaineers, cyclists, and hikers relying on precise location data.
The Solar Edition has a clear edge in prolonged outdoor tracking sessions due to its extended battery life. You can record long treks or all-day adventures without the need to recharge, which isn’t always feasible on the AMOLED model unless you compromise on display settings.
Fitness Age & VO2 Max
Advanced fitness tracking includes Fitness Age estimation, VO2 Max, and Training Status metrics—all powered by heart rate and activity history. These features provide detailed insights into your cardiovascular efficiency and overall fitness trends. The AMOLED model makes reviewing charts and summaries slightly more engaging thanks to its vivid display, but both models offer the same data points.
Move Alerts & Goals
Both watches provide periodic move alerts and customizable goals to keep you on track. You can set daily objectives for steps, calories, intensity minutes, or floors climbed. All alerts are customizable and can be adjusted based on your activity type or training plan.
In conclusion, for fitness tracking, there is no functional difference between the AMOLED and Solar Editions. Both offer elite-level tracking capabilities across an enormous range of sports and training styles. If you’re often outdoors and need endurance, Solar wins for practicality. But if visual clarity and interface readability matter more to you during training, the AMOLED may hold more appeal.
