If you want a running pace tracker watch that stays simple and focused on splits, the Garmin Forerunner 55 and the Polar M200 are two options worth comparing. The Forerunner 55 suits runners who want a fuller set of training metrics and a richer app ecosystem, while the Polar M200 suits runners who value a straightforward device with clear pace guidance and a comfortable, lightweight fit. Read on for how they compare on the criteria that matter most when you are choosing a pace-focused watch.

| Pace display and alerts | Customizable data screens, pace and lap alerts | Pace zones and target-pace guidance |
| Training metrics | Training status, recovery and load-style insights | Training load and recovery guidance |
| Battery life (manufacturer claim) | Multi-week smartwatch mode; roughly 20 hours in GPS mode | Around 24 hours of GPS tracking as specified |
| Water resistance | 5 ATM rating | 30 m (3 ATM) rating |
| Weight and comfort | Lightweight case with silicone band | Very light case, comfortable for all-day wear |
| Companion app | Garmin Connect | Polar Flow |
| Best fit | Runners who want more data and smart features | Runners who want a simple, focused pace tool |
Manufacturer specifications change with firmware updates and model revisions, so check the current spec sheet before you buy. The comparison below uses the features each company publishes and the patterns owners commonly describe.
Pace Tracking Accuracy and GPS
For a running pace tracker watch, GPS quality determines whether your splits mean anything. Both watches use satellite positioning, and both are designed to lock on quickly from an open outdoor start. The Forerunner 55 supports multi-satellite positioning, which owners often report helps in areas with tall buildings or dense tree cover. Garmin’s approach to GPS has been refined over many product generations, and its pace readings tend to be steady on road routes.
The Polar M200 also pairs GPS with wrist-based heart rate, and its pace data is designed to be reliable for everyday training. Runners who mainly run open roads or tracks will find either watch dependable. Runners in heavy urban canyons or under thick canopy may notice more pace jumps on any single-band GPS watch, so a short warm-up walk before starting can help the signal settle.
Winner: Garmin Forerunner 55, mainly for consistency in mixed environments and the multi-satellite support that owners frequently mention. A related read: Apple Watch Interval Running: A Step-by-Step Setup Guide.
Pace Alerts, Targets and Lap Controls
A pace tracker is only as useful as the feedback it gives you mid-run. The Forerunner 55 lets you set pace and distance alerts, configure lap settings, and choose which data fields appear on each screen. If you want to glance down and see current pace, average pace and lap pace together, you can build that layout yourself.
The Polar M200 leans on pace zones. You define a target pace range, and the watch signals when you drift above or below it. For runners following a structured plan, zone-based guidance can be more direct than managing individual alert thresholds. Interval sessions also work well on the Polar because the zones make it easy to hold a set effort without checking numbers every few seconds.
Winner: Garmin Forerunner 55 for customization, and Polar M200 for simplicity. If you value flexibility above all, Garmin wins this round.
Battery Life
Battery life matters most for long runs, ultramarathon training and multi-hour events. The Polar M200 is widely described as having strong GPS endurance for its class, and the manufacturer lists around 24 hours of GPS tracking. The Forerunner 55 is rated for roughly 20 hours in GPS mode, with much longer life in everyday smartwatch use.
In practice, most runners complete a training run well within either watch’s capacity. If you race marathons or plan long trail days, the Polar has a small edge on GPS endurance. Remember that battery figures assume specific settings. Heavy use of the display, music or continuous heart-rate recording reduces run time.
Winner: Polar M200 for GPS endurance on paper.
Training Features and Recovery Insights
Both watches go beyond pace. The Forerunner 55 offers training status and recovery-style guidance that many owners use to decide when to push and when to ease off. Its app pulls your runs into a detailed history, which helps if you like to track progress over months.
The Polar M200 provides training load and recovery feedback through Polar Flow, along with a clear summary after each workout. The data is presented in plain language, which some runners prefer over dense graphs. If you want a larger analytical toolkit, the Garmin ecosystem is broader. If you want a focused summary, Polar keeps things tidy.
Winner: Garmin Forerunner 55 for depth of training analysis.
Comfort, Weight and Durability
A running pace tracker watch sits on your wrist for every run, so comfort counts. The Polar M200 is noticeably light and its band is designed for all-day wear, making it a common choice for runners who forget they are wearing it. The Forerunner 55 is also light, with a silicone band that owners generally find comfortable during workouts.
For durability, the Forerunner 55’s 5 ATM water rating allows swimming in many cases, while the Polar M200’s 30 m rating is designed for splashes, rain and sweaty runs but not for swimming. If you swim, the Garmin has the edge. If you run in rain and mostly keep the watch dry otherwise, both are fine.
Winner: Polar M200 for lightness and everyday comfort, Garmin Forerunner 55 for water resistance.
Which Should You Choose?
- Choose the Garmin Forerunner 55 if you want customizable data screens, more training analysis and the option to use the watch for swimming.
- Choose the Polar M200 if you prefer zone-based pace guidance, longer GPS battery life and a lighter, simpler device.
- Choose the Garmin if you already use Garmin Connect or plan to add other Garmin devices later.
- Choose the Polar if you want a focused pace tool and a clean post-run summary without extra menus.
- Choose the Polar for long-distance events where GPS endurance is the priority.

FAQ
Is a running pace tracker watch accurate enough for race pacing?
Most GPS running watches are accurate enough for pacing during training and races, especially on open courses. Expect small variations on tight turns or under tree cover. Calibrate with a known-distance route if you want to check your watch’s accuracy against a measured course.
Do I need a heart rate monitor for pace tracking?
No. Pace comes from GPS. Heart rate is useful for effort control, but you can pace perfectly well without it. Many runners use pace for steady runs and heart rate for easy days.
How do pace alerts work on these watches?
You set a target pace or range, and the watch vibrates or beeps when you move outside it. Some watches also allow lap-based alerts. Check the settings menu after pairing, since defaults can differ.
Can I use a running pace tracker watch for swimming or cycling?
It depends on the model. The Forerunner 55 supports multiple activity profiles, including swimming in pool mode, while the Polar M200 is designed mainly for running and general fitness. Confirm the activity list before buying if multisport use matters.
How often should I charge the watch?
Charge based on your use. Daily smartwatch use with occasional GPS runs may need charging every several days to a couple of weeks. Long GPS sessions drain the battery faster, so top up before big runs. Consult the manufacturer’s manual for charging guidance specific to your model.
Conclusion
Both watches make a strong running pace tracker watch. The Garmin Forerunner 55 is the better pick for runners who want customization, deeper training data and swim-ready water resistance. The Polar M200 is the better pick for runners who want zone-based pace guidance, a lighter feel and longer GPS endurance. Match the watch to how you train, and your splits will be easier to read and act on.
