Compare Coros Pace 4 vs Garmin Forerunner 170

The Coros ecosystem scored well because training analysis is broadly shared across the range and app/training-lab access was praised as free.

Garmin’s training ecosystem is repeatedly praised as polished and deep, with strong analysis, coaching, and device integration.

Band quality was mixed: silicone was practical and straps were comfortable, while nylon drew complaints for holding sweat or moisture.

The silicone strap is soft, stretchy, and easy to replace, while the 170’s metal clasp feels nicer than the cheaper model’s plastic hardware.

Battery life was a standout across nearly every review, especially given the small case and AMOLED screen.

Battery opinions depend heavily on settings: raise-to-wake users often approach a week, while always-on users commonly report about three to four days. It trails the cheaper Forerunner 70 and several rivals.

Pulse Ox is considered a meaningful upgrade over the previous entry-level generation and adds depth to overnight health monitoring.

Bluetooth connectivity was positive in the limited evidence, with wireless headphones connecting without issue.

Temperature-related capability is valued for cycle tracking, but reviewers also note that Garmin reserves some skin-temperature features for more expensive models.

Brightness was usually strong outdoors and in daily use, though one reviewer found the default mode conservative.

The AMOLED is consistently described as bright enough for everyday and outdoor use, though it is not Garmin’s brightest panel.

Build quality was acceptable and functional, but the lightweight plastic design kept it from feeling premium.

The lightweight plastic case feels sturdy and better finished than older entry models. It avoids feeling cheap, even if it lacks premium materials.

Button controls were useful for shortcuts and navigation, but reviewers disliked the digital dial during runs and the limited action-button behavior outside activities.

Five physical buttons are a major usability strength, especially during runs, with gloves, or when sweaty hands make touch controls awkward.

The watch cannot take calls from the wrist because it lacks a microphone and speaker, limiting its appeal as a full smartwatch.

Calorie estimates stayed within about ten percent of a chest-strap comparison, which reviewers considered reasonably useful.

Charging convenience was mixed: the small USB-C adapter and keychain were handy, but needing a separate cable added friction.

Charging is quick, reaching a full charge in roughly 65 minutes and providing a substantial top-up in about 20 minutes.

Coaching and training features were useful and unusually complete for the price, though Garmin-style guidance and some plan options were still stronger elsewhere.

Garmin Coach, Training Status, adaptive plans, and Quick Workouts give beginners and regular runners unusually strong guidance. Quick Workout targets can be aggressive and its duration options may feel restrictive.

Comfort was one of the clearest strengths, with reviewers repeatedly praising the light, small watch for all-day and overnight wear.

The compact 41 g design is widely praised for all-day, sleep, and long-run comfort. One reviewer warned that the plastic rear casing may irritate sensitive skin during prolonged wear.

The companion app was praised for ease of use, improved polish, and transcription support, though voice content stayed inside the Coros ecosystem.

Garmin Connect remains free, easy to use, and effective for reviewing workouts and daily activity.

Contactless payments were missing, which reviewers treated as part of the broader smartwatch-feature gap.

Garmin Pay is a useful convenience and a key reason to choose the 170 over the 70. Its value depends on bank support and whether buyers can justify the price premium.

Customization was solid for sports fields, structured workouts, and button functions, with some limitations in watch-face flexibility.

Data layouts, swappable bands, report themes, and vibration patterns give the watch a pleasing level of personalization.

Display quality was a major upgrade, with reviewers repeatedly praising the sharp, colorful AMOLED panel.

The 1.2-inch AMOLED is colorful, sharp, and easy to read while moving. It is not as fluid or premium as flagship smartwatch displays, but testers still rate it highly.

Durability raised concerns because mineral glass and the low bezel were seen as less protective than tougher premium materials.

Despite its low weight and plastic build, the watch is considered sturdy enough for regular training and daily wear.

ECG is not available on the Forerunner 170, and reviewers note that buyers must move to a pricier Garmin to get it.

Fit was positive in the available evidence, with the 43 mm case sitting well on the wrist.

The 43 mm case fit testers securely and should suit many wrists, although the single-size design may not be ideal for everyone.

Core fitness tracking was viewed as accurate and useful overall, with some caveats around open-water swim and more difficult sensor scenarios.

Overall workout tracking impressed testers, with strong agreement between the watch and trusted comparison devices in controlled runs.

The display flashlight was useful in a pinch, but several reviewers said it could not match a dedicated LED flashlight.

A built-in flashlight is missing. Reviewers did not expect it at this tier, but several still considered its absence disappointing.

GPS accuracy drew the strongest agreement: most reviewers found tracks and distances excellent, with only occasional drift or margin-of-error complaints.

Most testers found all-systems GPS impressively close to multi-band reference watches on roads and open routes. Dense canopy, steep terrain, and technical trails produced drift or corner cutting for at least one long-term tester.

Health tracking was generally useful for big-picture trends, though reviewers found some accuracy limits when heart-rate and sleep data became more demanding.

Heart-rate accuracy was usually good for steady running, but reviewers repeatedly saw weaker results in intervals, cycling, gym work, or cadence-lock situations.

Steady running and treadmill readings usually tracked closely to chest straps. Rapid intervals, strength work, steep climbs, and some trail sessions exposed lag from the older sensor.

Mapping and navigation were the most common tradeoff: breadcrumb navigation worked for many runs, but the lack of offline maps pushed some reviewers toward Pace Pro or higher-end watches.

Breadcrumb routes are usable for familiar roads, but the absence of offline or topographic maps is a major limitation for trails, hiking, and exploration.

Materials quality was mixed: the plastic helped weight and comfort, but several reviewers called it budget or not lavish.

The fiber-reinforced plastic keeps weight down but does not feel luxurious, and the glass is below sapphire or premium Gorilla Glass standards.

Menu navigation was simple and practical, but one reviewer felt the interface lacked smartwatch polish.

The refreshed Garmin interface makes menus smoother and faster to move through than on earlier entry-level models.

Music controls were mixed: some reviewers praised phone media controls, while others noted absent or not-yet-available controls during testing.

On-wrist music control is convenient during runs and contributes to the Music model’s beginner-friendly appeal.

Onboard music support was limited because it depends on owned audio files and lacks Spotify, Apple Music, or other streaming-service integration.

The Music model supports useful phone-free playback and major streaming services. Reviewers like the feature but criticize the extra cost and unchanged storage capacity.

Operating system experience was praised for strong performance on the updated processor.

Garmin’s newer OS looks more polished, feels more modern, and aligns the watch with higher-end Forerunners.

Outdoor visibility was consistently good, with reviewers reporting clear readability in sunlight and varied conditions.

The AMOLED remains clear outdoors and is easy to glance at during runs, even though brighter flagship panels exist.

Pairing reliability was positive in the available evidence, with the reviewer reporting no issue connecting wireless headphones.

Recovery and training-load insights were useful for interpreting fitness, although one reviewer criticized Coros’s weekly training-load reset.

Training Readiness, Training Status, HRV, load, and recovery guidance are the watch’s most consistently praised upgrades. They make the 170 useful well beyond beginner-level run tracking.

Reliability was positive in the available evidence, with the watch described as a solid sports-watch performer overall.

Road-running performance is dependable enough for several reviewers to use it as a primary training watch. Reliability becomes more mixed in dense forest, steep terrain, and technical hiking.

Wrist-based running power and dynamics bring advanced training metrics to a relatively affordable watch and are strongly praised.

LiveTrack and location-sharing tools are valuable at this price, though live tracking still depends on carrying a connected phone.

Size options were a limitation because reviewers wanted more than one case size and found the single smaller size unsuitable for some users.

The compact single case works well for many smaller wrists, but buyers who need multiple case sizes have no alternative.

Sleep timing was often acceptable, but sleep-stage accuracy and the watch’s judgment of poor sleep were questioned by several reviewers.

Sleep tracking produced conflicting results: one tester found it close to trusted wearables, while another found REM and deep-sleep estimates inaccurate.

Notifications were a weak point, with reviewers calling them basic, tiny, or nearly useless while running.

Notifications are useful for daily wear, but one tester found the buzzing overly reactive during workouts.

Smartwatch features were consistently described as basic, making the Pace 4 more of a training tool than a full smartwatch.

The 170 offers payments, notifications, optional music, and apps, but it remains a training watch first and lacks the breadth of Apple or Samsung smartwatches.

Software smoothness was a strength, with reviewers describing the watch as snappy and lag-free, though less glossy than Garmin in places.

The refreshed software is faster, more polished, and easier to adjust before a run, with useful hidden settings and widgets.

Step counts were reported as aligning well with Garmin and Apple watches in testing.

Stress tracking was treated as accurate enough for a general picture when combined with sleep and heart-rate data.

Style and design were well received, with reviewers calling the watch sleek, clean, attractive, and helped by the AMOLED display.

Reviewers like the compact proportions, colorful two-tone options, and modern AMOLED look. The plastic construction keeps it sporty rather than luxurious.

Third-party app support was a clear limitation, with reviewers flagging the lack of app expansion versus smarter watches.

Connect IQ supports major services such as Spotify and YouTube Music plus a wide range of community apps and widgets.

Touch responsiveness was mostly good, but accidental touchscreen or dial input was a recurring annoyance.

The touchscreen is responsive without feeling overly sensitive, while physical buttons remain available for workouts.

The user interface was generally considered easy, simple, and understandable, even if it remains more basic than some rivals.

The updated UI is polished and easier to use, with quick access to settings and rich data. New Garmin users may still find the menu depth intimidating.

Value for money was the strongest consensus point, with every review framing the Pace 4 as unusually competitive for its price.

The base 170 offers a strong blend of training analysis, accuracy, and smart features. Value is less convincing beside the cheaper Forerunner 70, Coros Pace 4, discounted Forerunner 165, or the expensive Music upgrade.

There is no onboard voice assistant because the watch lacks a microphone and speaker.

Reviewers liked the workout voice notes when transcription worked well, but several treated the feature as niche or less convenient than it could be.

Watch faces were attractive by default, but reviewers wanted more customization and richer watch-face options.

Report themes add playful personalization, but the default progress-bar watch face can feel frustrating because its goals rarely align.

Water resistance was adequate for wet use and casual swimming, but reviewers did not treat it as a rugged diving-level feature.

Wellness insights such as HRV, readiness-style guidance, and training trends were helpful for many users, but not every wellness check felt actionable.

Body Battery, HRV, sleep guidance, Health Status, and lifestyle logging create a broad wellness package that supports recovery as well as training.

Wi-Fi is useful for downloading music on the Music model. The standard model lacks it, but reviewers found Bluetooth phone syncing adequate for normal use.

Reviewers praised the broad workout profile selection and multisport coverage, even while noting that some adventure-focused modes stay on higher-end models.

More than 80 sport profiles make the watch versatile for running, cycling, gym work, swimming, and outdoor activities. The main gap is a dedicated triathlon or multisport mode.
