According to our smartwatch expert
With the Garmin Forerunner 45S, you're always aware of your heart rate. The built-in heart rate sensor automatically measures your heart rate throughout the day. You'll also stay up to date on your burned calories, number of steps, and your sleep. The watch case is 1.56 inches, so it's also suitable for a thinner wrist. The smartwatch automatically recognizes the moment you begin your training. Nobody around to join you in your exercise? With the virtual partner, your watch will always give you a worthy opponent. You can easily connect the smartwatch to your Android or Apple smartphone via Bluetooth. That way, you can see notifications of WhatsApp, Facebook, and Instagram coming in on your wrist.
Note: a charger isn't included. Do you want to charge the watch via a socket? If so, order a charger separately.
This watch is recommended for a 13 to 15cm wrist circumference.

Bought a Garmin running watch as a backup and it does exactly what I minimally need: time, heart rate, distance, speed, laps. Also general activity and sleep tracking, but that is not a goal in itself. Works fine.

Nice watch for a nice price with many running functions. You can set up all kinds of training programs via the Garmin app, but also, for example, via TrainingPeaks (via Garmin app). Watch charges quickly and battery lasts long enough. The watch has a beautiful design, so you can also wear it as a "normal" watch.

Good watch to record your run. If you follow a schedule you can set it as a workout, then you will receive feedback while walking if your pace/heart rate/cadence value is higher or lower than your set goal. Afterwards, the route and data are clearly visible in the Garmin Connect app and, if necessary, linked also in strava. I believe you can also download ready-made Garmin workouts.
