Buttons
I love the fact that this has buttons and not a touch screen. When running, now that I'm familiar with the interface, the button navigation allows me to quickly get to the items I'm looking for and see the data that I want without having to worry about tapping a super small screen with sausage fingers. Buttons are for runners.
Accuracy
When it comes to counting steps, and miles this thing is spot on. I'm not sure how they get it done but the watch performs well for logging and tracking my steps and running. Milage is consistent and accurate. It's really great to know that even indoors walking through a large hospital going up and down multiple floors this thing keeps track of what I'm doing.
Smartphone Notifications:
Very nicely done. Once familiar with the interface it is easy to quickly respond with preset messages. The only think I worry about is privacy. I don't want everyone knowing when I'm arguing with my wife or when we're about to make up. So I'm hesitant to leave it out when I have to scrub for a long operation. I'm a private person though. You may be the type to put that stuff on blast.
Music:
Love that Spotify is available for this as an internet free option (i.e. no internet or phone required to playback the music). You are able to create playlists on spotify and download the playlists to your phone. There are other options to see playlists associated with recently played music. I use this all the time while running... it's unsafe but makes the run that much more enjoyable.
Ecosystem:
The apps and extended functionality/data screens are really for the athlete. There are a few rather clunky apps that are popular and extend the watch a little bit more than just an activity tracker. I use the minute weather app that tells me if there is going to be rain in the next 60-120 minutes more than I thought I would living in the south. The watch faces are... ok. Love the way that data screens can be customized on some of them.
Battery:
Excellent. 4d without a charge. Left my charger accidentally at work with 10% left on the watch. Just hanging around the house for 12h I was later at about 4% before having to go and get the charger. Listening to and downloading music drain the battery pretty fast. Downloading is the worst... But otherwise the efficiency of the watch during regular use is great. I'm very happy with the battery. I do charge to 100% before my runs and and I run ~ 3 x week. A 1h run will take me to >80% from full charge. I'm pleased.
Screen
Legible outdoors. Light button helps you see at night. It is always on (Apple tried to sell that as a feature...). I'm happy with the resolution for what this watch does.
Coach
Love the Garmin coach and the integration with the watch. You have to set it up on the phone app but it just rolls from there. I have used it to help me decrease my mile times and extend my distance. I have no idea how they calculate the VO2Max and, despite googling this, it remains a mystery to me. If someone knows... post. That said, it's trending in the right direction which I hope is not a gimmick but truly reflects me getting fitter. The Goals for each training setup are reasonable and allow you to target completion or times. Love it.
Alarm:
This sounds dumb but I have now switched almost exclusively to the Garmin to wake me up. It doesn't wake up my wife which my phone does... the vibrate just makes me get up... hard to explain but a big plus.
Heart rate:
Works perfectly. i've used equipment at work to check this (pulseox heart rate in a hospital setting) and it is accurate. Period.
Cons:
Bezel
Scratches really easily. Decided to buy a screen protector and something to go on top of the bezel. Wish it didn't scratch so easily.
Lagging
Rarely the watch lags when buttons are pressed and takes a while to catch up. I think this is analogous to "waking up" the watch from hibernation or something... but it isn't a problem to me.
Band:
Changed the stock band. Didn't like it too much. But there are plenty of options out there depending on your taste
Overall Loved the watch. Hope this review helps.
Once I got the replacement watch it worked just fine from the start!
There are a lot of good features like V02, recovery time recommendations, Training load, Anaerobic and Aerobic effort, nice watch faces available, and the GPS sync/tracking and music all work well!
Sleep tracking seems to work pretty good as well and syncs up pretty well with how I fell in the morning (rested or not).
Effort level (heart rate based) seems to also sync up pretty well with the effort that I feel I'm exerting during a run so I'm pretty happy with that metric too.
The main thing that I don't like is that certain Bluetooth headsets will cut out a little as you run if you keep the watch on your left hand because of Bluetooth Low Energy to save battery. On many headsets the primary earbud is in right ear so your body will get in the way as you swing your left arm back and forth while running. My solution was to move the watch to my right hand while running and back when I wear it day to day. You could also just buy a headset that is on their list of compatible headsets.
And this user's list:
Search Google for “Forerunner 645 headphone-compatibility-experience-table”
The only other thing that I'm not a fan of is the charge connector. It's the old style connector and it takes a few seconds to get it seated properly and it can shift around if you move the cable.
There are many activities that it tracks but I primary use it for running and for that it works great and does what I wanted it too!
Overall I feel that this watch has helped me perform more focused training which is why I bought it!
It gives me the information to work on my anaerobic (short bursts and speed improvement) and aerobic (endurance) fitness levels and know whether I'm maintaining, improving, or overreaching. The headset thing was a little annoying at first but given the price and features I can deal with moving it to my right wrist for runs. I also could have bought a different headset but I wanted the Jabra Elite 75t for other benefits.
The watch also has a classier look than the other running watches so I can wear it daily and it doesn't look out of place with a button up shirt and slacks at work.
I purchased a screen protector and a protector ring that have worked pretty well to keep it protected.
I cut out a small piece of an old gift card to put between the watch face and the clamp to help distribute the spring force across the watch face so it doesn't cause the screen protector to shift or come loose.
Screen protector:

Protector ring:
https://www.amazon.com/gp/product/B083CV98XM/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1
Transferring music to the watch is simple and my PowerBeats 3 connected easily. The watch looks great, is light weight, and is comfortable to wear during the day/night and on runs. Garmin Pay is still pretty limited, but hopefully that will be expanded through the year, like Garmin has promised. We'll see, but I can count on one hand the number of times I just Apple Pay on my AW, so it's not a huge deal to me. If it is to you, look closely at the banks it currently supports. It won't take long. https://www.garmin.com/en-US/garminpay/banks/
Overall, this is a great watch that hits everything I've been looking for. More importantly, it executes those things exceedingly well.

O carregamento do sinal se gps é muito rápido.
Ahora, mi plan es usarlo para bicicleta, y aún sigo familiarizándome con él. Hasta ahora no me ha decepcionado, todas las dudas que eh tenido o funciones que en algún momento asumí no tendría las eh comenzado a comprender mejor después de descarga el manual completo de la página de Garmin. Creo que me hubiera servido antes de comprarlo de hecho, para asegurar que cumple con las expectativas.
Como sea el producto es muy bueno, excelente calidad y hasta ahora no lo eh visto a un mejor precio, por lo cual estoy muy satisfecho...
Leí muchos comentarios desde que el producto no estaba nuevo hasta que la batería no funcionaba, desde que lo conecté se actualizó a la última versión, configuré Spotify, descargué mi playlist y salí a correr, todo perfecto, GPS se conectó rápido, preciso, y OJO, yo tengo audífonos JayBird X2 (muy viejitos pero funcionan como desde el primer día) y NO tuve fallas o cortes de música, todo perfecto. Segundo día le conecté un podómetro Adidas que tenía guardado y la carrera fué mucho más precisa en los pasos y distancia por obvias razones. El contraste de la pantalla ayuda muchísimo si corres en el día, si utilizas lentes como yo y tienes astigmatismo, como con todos los relojes vas a batallar para verlo en las noches o con poca luz, pero es algo normal.
