  1. Evul Jeenyus

    A little bit about me: I am a fairly average guy. Not a triathlete and probably not training for a marathon. I am just a middle-aged guy fighting against the natural descent into dad-bod slothdom. I go to the gym 3-4 days a week and mostly swim and do some weights, kettlebells, etc. I “run” once in a while but most of the time just do a brisk walk around the track a few days a week. Ok, enough about me. Let me share my thoughts on the watch.My desired requirements:More activity tracker than a smartwatch. Good battery life. Reasonably accurate activity tracking (hopefully it will improve with more calibration). Lap swimming – more importantly, I wanted a watch that would be able to guide me through a workout.PROS:Nice shape and sizeGreat displayI like the fact that it is not a touchscreenExcellent swim training mode (it buzzes and dings on the last length of an interval/set, so you don’t necessarily need to keep track)Great battery life (so far)Music storage (I have not used this yet)CONS:Garmin Pay is not functioningWhile I do not like touchscreens, getting used to the buttons takes a little timeNot the cheapest watch out thereOther watches tried:Garmin Fenix 5 with sapphire glassPROS – amazing features. Bomber construction. Great design. Accurate tracking. Swim features were great. A multitude of pre-installed activities.CONS – display a little dark because of sapphire glass. Limited app selection on Garmin Connect. Even though this is a lot smaller than the predecessors, I still think it is a pretty hefty watch. The last nail in the coffin for this incredible watch was close to 50% price difference for a watch that didn’t hit everything I wanted.Samsung Gear Sport 2PROS – reasonable price point. Great display. Samsung Pay worked well. Pretty nice design. Good variety of apps available. Can store music on board.CONS – More smartwatch than a fitness tracker. Fitness tracking was inaccurate. Battery life was not great. Better than an Apple Watch, but not bad compared to the Fenix 5. Only had swim tracking, not workout guidance and tracking is inaccurate.Samsung Gear Fit 2 ProPROS – excellent price point. Display nice and sharp. Battery life was pretty good.CONS – Inaccurate activity tracking – it was .5 miles off over 2-mile run. No Samsung Pay. Not wild about the shape or aesthetic. Only had swim tracking, not workout guidance and the tracking was inaccurate.Garmin Vivoactive 3 HRPROS – Decent pricing for what you get. Nice size and shape. A good set of options.CONS – Lacking swim workout function. Battery life could be better. Touchscreen overly sensitive.

    This watch is exactly what I’ve been waiting for, I’ve had it for almost 3 weeks and it’s perfect for my needs. I typically run 20-25 miles per week and was sick of carrying my phone to listen to music. Within 10 minutes of opening it, I had it loaded with my running playlist and was out the door. Since this is my 3rd Garmin watch I already have an account with them plus have Garmin Connect on my phone which saved time. My (Mac) computer recognized the watch as soon as I plugged it in and launched the software. The iTunes library popped up when prompted and I simply checked the playlist I wanted to add. I didn’t realize that this watch had only been tested with a limited number of earbud brands but luckily the 2 pairs I own are on the list. My primary pair are Trekz Titanium and they paired instantly when in pairing mode. Being left handed I wear the watch on my right wrist and I have had zero interruptions while music is playing. You may want to check to see if your earbuds are on the approved list before purchasing, I would have been bummed if mine wouldn’t have worked…The GPS connects much quicker than my previous watch, the Forerunner 245. The watch is lightweight, has a large and easy to read screen and looks a little dressier than my previous sport watches because of the metal rim around the face plate. I’ve had no issues with the battery, I took it for a 13 mile run yesterday and continued to play music for 2 hours while walking around downtown after my run. The battery still had a good charge and was at 70% when I got home. The home screen gives you 4 different pieces of customizable data: time, weekly mileage, date and time of sunset (I changed time of sunset to calories burned and added a step counter on the home screen). I wish I could change weekly mileage to monthly mileage but hopefully that option will come with an update. The 645 music is a little smaller than the Forerunner 245 and a lot smaller than my husband’s Fenix (I will include comparison photos) which I love because my wrists are small. Overall I am very happy with this watch and would highly recommend it!

    Doesn’t pair well with my Beats headphones but that is the only complaint. Absolutely love the watcb

  4. Leo B

    Once you remember where all the buttons are, the menus are very logical.Tons of features and they all work well. Small and lightweight. Ive owned this for about a month, and know complaints.Used Garmin Pay- Very easy to setup and use.Haven’t really used music yet. My bluetooth headphones are too old to work well. It was easy to load music.All Garmin running features work great as usual. built in HRM is great.Very Happy

  5. Dad

    Thought this watch was discounted 30.00 for amazon. Come to find out after many calls to Garmin it’s a Asian version that is not compatible for many headphones, music and updates. I never saw any disclaimers on the description. I would have paid the extra 30.00 for a USA compatible watch.

  6. Zachary Cornell

    This is a very solid watch, no touch screen which is nice when sweating.

  7. Robin Jespersen

    This was a gift for my son for Christmas. He is a long distance runner… half marathons, marathons & even 100 mile relays. I waited until he was able to use and, very happy! Convenient run tracking as well as music. Unsure of battery life since new but he is thrilled with this watch!

  8. Eduardo

    O modelo mudou bem em relação ao Garmin Forerunner 630. A pulseira é mais fina e flexível o que gera maior conforto no pulso. A tela também está com uma melhor visualização e cores o que ajuda muito no momento dos treinos/corridas. O sensor cardíaco no pulso além de fornecer excelentes informações dá mais liberdade e conforto se comparado com o uso da sinta cardíaca. Outra novidade é o abandono da função “touch” e uso dos botões para acessar os menus e funções. Recomendo a compra.

  9. Jason M.

    I would like to return.

  10. Jennifer Lentz

    I wear my Garmin every minute of the day as I have my previous 2 other Garmins I have owned. They become part of my body! I run every day and love some of the new features on the 645. Heart rate not always accurate though. Indoor treadmill running not terribly accurate but when outside using the GPS functionality, I feel it is pretty accurate at measuring distance and time. Garmin makes a quality product.

  11. Baxter

    I ordered the FR645 Music and received the version without the music! All order and delivery details say FR645 Music. While I did get in the BF sales, I am feeling absolutely conned to say the least!

  12. Not Happy

    Similar to another reviewer I feel robbed! Ordered a 645 Music and the 645 arrived.

    **just spoke to customer service at amazon and they can’t do anything. I would not make large purchases from amazon if I were you. Should have gone to Best Buy. Avoid at all costs. I purchased online last May 2019. It has not even last 1 year. It no longer syncs with my phone, I cannot recieved text messages. It constantly disconnects from my phone even where I am right next to it. The music cuts in and out Avoid this seller there is no warranty like if you purchased in a store. I’m so disappointed. It worked great for the first 6 months is all I can say about it. Save your money buy in store.

Garmin Forerunner 645 Review: Paying a Premium for Music ...

Garmin Forerunner 645. The long-awaited feature isn't as easy to use as it could be, but the ability to track runs, cross-train with a variety of built-in workouts, pay for items on the go and listen to pumped-up playlists on one device makes the new Forerunner worth the high price tag — for some athletes.
