For most beginners, the Forerunner 55 is enough to start running, while the Forerunner 165 is the better choice if you want a larger AMOLED touchscreen and more health and everyday features. Neither is inherently too advanced: Garmin positions the 55 especially for people new to running and describes the 165 Series as suitable for athletes of all skill levels. The practical choice comes down to screen and controls, training features, battery expectations, health tracking, music needs and the price available in your region.
Quick verdict: which beginner should buy each watch?
Choose the Forerunner 55 when your priority is straightforward run tracking, physical buttons, a sunlight-visible MIP screen and the longest stated battery estimates. It includes GPS, wrist-based heart rate, suggested workouts and adaptive Garmin Coach plans, so it covers the core needs of someone preparing for a first 5K, 10K or half marathon.
Choose the Forerunner 165 when you would rather have a brighter, larger AMOLED touchscreen, more detailed health and sleep information, additional activity profiles and newer training guidance. Its display is easier to navigate for people who prefer touch controls, although the touchscreen is not automatically better in rain, cold or during a hard interval.

What both watches provide for a new runner
A beginner does not need to master every metric on day one. Both models can record outdoor runs with built-in GPS, measure heart rate at the wrist and present guided training suggestions. Garmin’s descriptions also include recovery-related information and activity and wellness tracking, giving a new runner a way to build a routine without buying a separate coaching service.
Forerunner 55 beginner tools
- Built-in GPS for recording route, distance and pace.
- Wrist-based heart-rate monitoring.
- Daily suggested workouts.
- Adaptive Garmin Coach plans for 5K, 10K and half-marathon goals.
- PacePro pacing guidance, a finish-time estimator, cadence alerts and recovery time.
- All-day activity and wellness features, including stress, relaxation reminders and Body Battery.
- Menstrual-cycle and pregnancy tracking in Garmin Connect, as listed by Garmin.
Garmin introduced the 55 as a watch for all skill levels, with particular emphasis on people new to running. Its launch description says the watch presents informative and digestible data to help people reach running goals and support a healthy lifestyle. That positioning makes the 55 a sensible starting point when you want the essentials without a large menu of newer features.
Forerunner 165 beginner tools
- Built-in GPS and wrist-based heart-rate monitoring.
- Personalized daily suggested workouts.
- Race-adaptive training plans and Garmin Coach plans for 5K, 10K and half-marathon distances.
- Completion-time predictions.
- Wrist-based running power and running dynamics.
- Training Effect and course support.
- More than 25 activity profiles in the 165 Series.
- Sleep monitoring, sleep score and sleep insights, nap detection and a morning report.
- Smart notifications when paired with a compatible phone.
These functions are guidance and tracking tools, not a guarantee of race performance and not a replacement for a qualified coach or medical advice. You can safely ignore advanced metrics until you are comfortable with the basics of pacing, consistency and recovery.
Display and controls: AMOLED touch versus MIP buttons
| Specification | Forerunner 165 | Forerunner 55 |
|---|---|---|
| Display type | AMOLED, with optional always-on mode | Sunlight-visible transflective memory-in-pixel (MIP) |
| Display size | 1.2 inches (30.4 mm) | 1.04 inches (26.3 mm) |
| Resolution | 390 × 390 pixels | 208 × 208 pixels |
| Touchscreen | Yes | Not listed by Garmin |
| Weight | 39 g | 37 g |
| Water rating | 5 ATM | 5 ATM |
| Band standard | 20 mm industry-standard quick-release | 20 mm industry-standard quick-release |
The figures in this table are Garmin manufacturer specifications, not independent readability or comfort tests. The 165’s 1.2-inch, 390 × 390 AMOLED panel gives text, workout prompts and watch faces more room than the 55’s 1.04-inch, 208 × 208 MIP panel. AMOLED also supports an optional always-on mode, which can make the watch feel more like a conventional smartwatch but may affect battery consumption.
The 55’s MIP display is designed to remain visible in sunlight and works with physical controls rather than a touchscreen. Buttons can be easier to operate when your fingers are wet, when you are wearing gloves or when you do not want to swipe through a workout. The 165’s touch interface is attractive for everyday navigation, but you can still use its buttons for many workout operations.
Rank #2
- Easy-to-use running smartwatch with built-in GPS for pace/distance and wrist-based heart rate; brilliant AMOLED touchscreen display with traditional button controls; lightweight design in 43 mm size
- Up to 11 days of battery life in smartwatch mode and up to 19 hours in GPS mode
- Reach your goals with personalized daily suggested workouts that adapt based on performance and recovery; use Garmin Coach and race adaptive training plans to get workout suggestions for specific events
- 25+ built-in activity profiles include running, cycling, HIIT, strength and more
- As soon as you wake up, get your morning report with an overview of your sleep, recovery and training outlook alongside weather and HRV status (data presented is intended to be a close estimation of metrics tracked)
The weight difference is only 2 g: 39 g for the 165 and 37 g for the 55. Both have a 5 ATM water rating and use 20 mm quick-release bands. The rating and band dimensions do not, by themselves, establish suitability for any particular water sport or guarantee that every replacement band listing is compatible; confirm the exact model before buying an accessory.
Training support: how the two watches help you progress
Starting with a 5K
Both watches can support a first 5K through suggested workouts and Garmin Coach options. On the 55, Garmin describes free adaptive plans for 5K, 10K and half-marathon distances. The 165 Series adds race-adaptive planning and personalized daily suggestions. In either case, enter a realistic goal and follow the prompts as one input into your training rather than treating the schedule as a promise of a particular finish time.
Understanding the extra 165 metrics
Running power, running dynamics, Training Effect, courses and completion-time predictions give the 165 a wider training vocabulary. They can be useful once you understand pace, effort and recovery, but they are not prerequisites for beginner progress. A new runner can begin with time, distance, heart rate and perceived effort, then use additional metrics when a specific training question arises.
What the 55 leaves out
The 55 has a narrower feature set, but that can reduce the amount of information you must interpret. It still includes PacePro, cadence alerts, recovery time and finish-time estimation according to Garmin’s launch information. If your goal is simply to follow a structured plan and record runs, the missing 165 features may not affect your decision.
Battery life in real use
| Mode | Forerunner 165 | Forerunner 55 |
|---|---|---|
| Smartwatch mode | Up to 11 days | Up to 2 weeks |
| Battery Saver smartwatch mode | Up to 20 days | Not stated in the cited comparison |
| GPS-only GNSS mode | Up to 19 hours | Up to 20 hours in GPS mode |
| All-Systems GNSS mode | Up to 17 hours | Not stated in the cited comparison |
These are Garmin’s quoted maximum estimates, not a promise of a fixed interval between charges. The 165 owner manual says actual battery life depends on enabled features, including activity tracking, wrist-based heart rate, phone notifications, GPS and connected sensors. Screen settings, notifications and the selected satellite mode can therefore change the result.
Rank #3
- Easy-to-use running watch monitors heart rate (this is not a medical device) at the wrist and uses GPS to track how far, how fast and where you’ve run.Special Feature:Bluetooth.
- Battery life: up to 2 weeks in smartwatch mode; up to 20 hours in GPS mode
- Plan your race day strategy with the PacePro feature (not compatible with on-device courses), which offers GPS-based pace guidance for a selected course or distance
- Run your best with helpful training tools, including race time predictions and finish time estimates
- Track all the ways you move with built-in activity profiles for running, cycling, track run, virtual run, pool swim, Pilates, HIIT, breathwork and more
The 55 has the longer stated smartwatch estimate—up to two weeks versus up to 11 days for the 165—and a one-hour advantage in the quoted GPS figures. If you dislike charging or routinely take long GPS activities, that difference favors the 55 on paper. If you enable the 165’s always-on display, use frequent notifications or select more demanding GNSS settings, expect less than the maximum estimate.

Features listed for the 165
Garmin’s comparison lists sleep score and insights, Pulse Ox measurements, and Garmin Pay for the 165. Pulse Ox can be configured for spot checks, during sleep or all day. The 165 announcement also mentions sleep monitoring, nap detection, a morning report and smart notifications.
Pulse Ox and sleep data are wellness features, not medical diagnoses or proof of measurement accuracy. If a health reading concerns you, use an appropriate medical device and speak with a clinician rather than treating a watch estimate as a diagnosis. Garmin Pay availability can also depend on supported cards, banks and country.
Features listed for the 55
The 55 announcement emphasizes all-day activity and wellness tracking, including stress, relaxation reminders, Body Battery and menstrual-cycle or pregnancy tracking in Garmin Connect. Garmin’s side-by-side comparison does not list corresponding entries for sleep score and insights, Pulse Ox or Garmin Pay on the 55.
This is not a statement that the 55 has no wellness information; it means the cited Garmin comparison identifies a different set of features for each model. Review the exact regional specification if one particular health or payment function is essential to you.

Music: the standard 165 is not the music model
Phone-free music storage and listening with wireless headphones require the Forerunner 165 Music variant. Garmin’s announcement distinguishes that model from the standard Forerunner 165. Do not buy the regular 165 expecting to leave your phone at home with locally stored playlists.
If you normally carry a phone, the standard 165 or the 55 can still meet a run-tracking need while the phone handles audio. If phone-free listening is a deciding requirement, compare the price and availability of the 165 Music specifically; it is a separate model, not an automatic feature of every 165.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which watch is easier to use as a first running watch?
Why the 55 can feel simpler
- Physical controls avoid touchscreen gestures during workouts.
- The MIP display and narrower feature set focus attention on core run data.
- Garmin explicitly targets beginners in the 55’s product positioning.
- Its quoted battery estimates reduce how often a new user has to charge it.
Simplicity does not mean the 55 is limited to beginners. Garmin describes it as suitable for all skill levels, and the included plans and pacing tools can remain useful as your running develops.
Why the 165 can feel easier for some people
- The larger 1.2-inch AMOLED screen provides more display area.
- Touch navigation may feel familiar if you use a smartphone or smartwatch.
- Sleep score, morning report and other everyday features put more context in one device.
- More than 25 activity profiles make it more adaptable if running is only one of your activities.
More features can also mean more menus and more decisions. During setup, hide or reorder data fields you do not understand yet, then add them as your training questions become more specific.
Quick wins for a faster PC:

- Charge and pair the watch. Use Garmin’s supplied proprietary plug charger, then follow the on-screen pairing process with the Garmin Connect app on your phone.
- Set your profile and goal. Enter the personal information requested by Garmin Connect and choose a realistic 5K, 10K or half-marathon objective if you want a guided plan.
- Choose a simple run screen. Start with fields such as elapsed time, distance and pace. Add heart rate only if you know how you want to use it.
- Start an outdoor run. Select the run activity, wait for GPS to acquire a signal outdoors, then begin. Keep the watch in a consistent position on your wrist so the optical heart-rate sensor can work as intended.
- Review the result. After saving, look first at time, distance and how the effort felt. Use suggested workouts and recovery information as guidance for the next session.
- Adjust gradually. Once the basic routine is comfortable, explore Garmin Coach, PacePro, sleep information, courses or additional activity profiles that answer a real need.
The exact menu names can vary by software version and regional setup. If a training plan, payment feature or notification option does not appear, check device software, Garmin Connect settings and regional availability before assuming the watch is defective.
How to decide when the 165 is worth choosing
Because the cited official comparison does not establish a current like-for-like US price, there is no evidence-based premium that can be declared worthwhile for every buyer. Use this decision process instead:
- Check the local prices on the same day. Compare the regular 165 with the regular 55, and compare the 165 Music only with a model that includes the features you actually need.
- Identify your must-have control style. Choose the 55 if physical buttons and a MIP screen are non-negotiable; choose the 165 if AMOLED and touch are central to your preference.
- Decide whether the extra health features matter. If sleep score, Pulse Ox, Garmin Pay or nap detection would change your purchase, the 165 has the stronger listed feature set.
- Consider charging habits. The 55 has the longer quoted smartwatch and GPS estimates, while the 165 offers more battery modes and GNSS figures.
- Confirm music requirements. Select the 165 Music only if onboard storage and phone-free listening are important.
Limitations and expectations before you buy
- Specifications are not accuracy tests. The display, weight and battery figures above come from Garmin. No independent comparative test or market survey establishes that one watch records GPS, heart rate or sleep more accurately than the other.
- Battery maximums are conditional. Enabled sensors, GPS settings, notifications, activity tracking and display behavior all affect runtime.
- Health metrics are informational. Neither a sleep score nor Pulse Ox reading should be used as a medical diagnosis.
- Regional functions can differ. Payment support, pricing, plan availability and some connected features may depend on country, bank, phone and software.
- Training plans are not guarantees. A suggested workout or adaptive plan cannot promise a finish time or replace professional coaching.
- Accessories need model confirmation. Both watches use 20 mm quick-release bands, but verify the exact listing. Garmin’s charger is proprietary, so replacement chargers must be specified for the watch.
Bottom line for beginners
Buy the Forerunner 55 if you want an uncomplicated, button-controlled running watch with the core tools for structured beginner training and Garmin’s longer stated battery estimates. Buy the Forerunner 165 if you value its larger AMOLED touchscreen, sleep and health additions, broader activity support and newer training presentation. The 165 is not too advanced for a beginner, and the 55 is not merely a starter toy; each is appropriate for a different definition of “better.” Check current regional pricing and choose the feature set you will actually use.
