Forerunner 255 Series
Long battery; but wrist HR tracking is inconsistent.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
I went to Polar Pacer for 18 months after always being Garmin. It had to be sent for warranty repair 3 times and broke again when I finally gave up. Software issues were constant. I'll never buy another fitness watch that isn't Garmin again.
I have a Polar Pacer and my wife has the Pacer Pro. We've had them for 3 years plus and have been very happy with the performance and reliability. We are regular but not hard-core runners
Polar is great for stats especially if paired with heart rate monitor. I have Polar Pacer for watch and H9 for strap. The only downside is im unable to play music - but you said not relevant so might be good option for you.
Polar pacer is not heavy and is great for tracking sleep too. GPS, never had a problem.
Sad but they are running out of time , basic up to date watch is the M3€400, THE Pacer Pro, Pacer, and the Ignite are all out of date( i have the Pacer). Coros, Amazfit, Huawei, Suunto caught up. Pity ,but never forget what happened to Nokia, Blackberry. I wish them all the luck in the world 🙂
I ended up ordering the Polar Pacer and H9 this week. I would get the Unite, but I was worried the crappy battery life would make me angry like the A360 did. I am a huge fan of Polar's heart sensor and the app, that's what I'm here for... I never purposely used GPS but I noticed my phone would somehow track my movement during a bike ride when the watch was tracking a workout and connected (for text notifications).
Polar Pacer, because it has buttons and is quite reliable for swimming
