Garmin Forerunner 955

Pretty good watch so far - I've had it for 4 weeks now. Pros: - Measures many different components of health/fitness in an easily digestible way (on the app) - Reliable battery so far (lasts about a week easily) - Somewhat customisable (you can show quite a few things on the watch face like heart rate, steps, temperature, time etc.) Cons: - The watch needs to be strapped pretty tightly to record your heart rate (I find switching from one wrist to the other reduces discomfort) - The watch needs to be strapped extra tightly at night to record sleep (if it's even a little too loose you lose a whole night's data)

Good for measuring (roughly) things like: - VO2 Max - Resting heart rate - Heart rate variability - Sleep - Training readiness - Stress

Loved the watch til Bluetooth died – Was a great watch for about a year until the Bluetooth stopped working. Once that happens it’s useless. I bought it directly from Garmin and they’ve been trying to worm out of consumer guarantees as the retailer/manufacturer
