    Great battery life, super screen and well built, shame there’s no maps but all in all I think it’s worth it as the amoled screen is great and the GPS is amazingly accurate.Previous I had a Fenix 5X this is a great replacement at a fantastic cost and I find the button controls are much more practical to use compared to touch screen given it’s a Outdoor watch.

  2. Charlie Johnston


    I bought this watch to replace an old Samsung Galaxy. The lack of a touchscreen took a little getting used to but once I got used to the watch it wasn’t an issue. The battery life is excellent, 18 days charge is amazing. I have changed the strap as I don’t like silicon ones, which is a personal choice. There are many features I haven’t used yet. I do think this is good quality and good value for money.

  3. Mr. Simon J. Connah


    After owning this for a few months now, I am glad I went for the Garmin rather than an Apple Watch. Battery life is 28 days and does all the notifications I require.

    It’s rugged, doesn’t feel like you’ve got a block of glass strapped to your wrist that might shatter at any moment. The battery life and UI are great for me, simple but plenty capable, I went to a more full featured smart watch for a while from a big phone brand and couldn’t stand having it on charge all the time, and found no use from all its extra abilities. I would, and have in fact, recommend Garmin watches to my family and friends.

  5. Joe Warrington


    Excellent brand. Really solid products. Had the previous model for 5 years. Wouldn’t go anywhere else. It’s amusing that people pay double the price for apple products that need to be charged every 10 mins.

    Great watch, lots of settings to master tho’

  7. David R. Grist


    Shocked at how good this watch is. I only set it up this morning, which was simple and quick.I like how the watch looks fairly basic and old fashioned, but underlying those minimal details are so many different additional options.Not sure on the other reviews I’ve read about people finding it difficult to navigate using the buttons. I agree, it’s not as straightforward as the Vivoactive 5 I had, but it took me about 10 minutes to be able to fully learn and navigate the whole system.I’d definitely recommend this watch. Whether you want it for outdoor or indoor activities, this watch covers everything. If you want the glam of the modern swipe watches, I’d avoid buying this as you’ll be disappointed with the old standards of button pressing.

    Absolute rubbish. Won’t connect to the app. Waste of time. Tried all the trouble shooting hints just rubbish. Another tech that failed.

    Great fitness watch
    Love this watch, has everything you need. I was looking at the data as I use for running and it has the same run features as the more expensive 265.The torch and redshift actually come in handy too.Battery life is fantastic, getting 2 weeks and that’s also using it for 1-2 hr daily activities

  11. VJ

    Great No Nonsense Watch
    I am using this watch for 10 days now. It has everything I wanted. It is giving me a great battery backup. GPS Accuracy is amazing. Will surely recommend it. Just remember it has no touch feature, it uses buttons.

    Top top top
    Wat is dit een top aankoop geweest had hiervoor een apple watch maar de batrij hiervan gaat wel 18 dagen mee dus niet zoals me oude elke avond opladen hierdoor blijft hij veel langer om me pols en merk ik hem bijna niet je kan een hele hoop dingen meten en inzien en werkt echt top echt wen aanrader
