Zeblaze Crystal 3 IP67 Waterproof Smart Watch

The full title for this watch is the Zeblaze Crystal 3, 1.3 inch Heart Rate Blood Pressure  Smart Watch and it is USB charging and light-weight – also the straps are detachable and one of the receptacles on the watch for the strap is also a USB plug. Dead easy as is the setup with the freely downloadable app “Happy Sports”. The presentation box is really nice and is reminiscent of more expensive watches. I’ve done a short video to go with this.

The watch has a range of 4 watchfaces, handles pulse rate, blood pressure, blood oxygen, sleep monitoring and tracking, various sports (step count) functions and calories. The sleep info is broken down into deep and light sleep. I found it simple to set up and simple to use.

The watch has high precision sensors and up to 7 days battery life (I’ll confirm that later). Did I mention remote photography, music control, smart alarm clock, real-time weather and a timer along with bluetooth 4. Charging takes around 2 hours. The manual (unlike some) contains 8 pages of useful English plus the title page.

Possibly most importantly the price is £14.15 just after Christmas 2019 with free shipping. Take a look (it’s all in the link at the top).

I must say that like many other smart watches, the display would not be too visible in bright mid-summer Spanish sun but other than that it is fine. Certainly in typical weather in the UK and some European countries it is good to go. Note how the strap tucks in – a neat trick which others should use (add-on straps for my Samsung watch use a similar design).

  1. Mine keeps disconnecting from the phone and wont connect automatically. Are you facing the same issue?

    1. I had no issues with the Zeblaze Crystal 3 but I’m fairly sure I left it in the UK (I’m in Spain) and so can’t comment other than to say it connected to my Xiaomi Pocophone F1 no problem. Sorry.

  2. These Crystal 3 watches are garbage. Almost impossible to get it to connect. Half the apps on the watch don’t work. It constantly disconnects. Touch screen doesn’t work a lot of the time. It is always forgetting the info it has collected.

    1. Would it be more accurate to say YOUR Crystal 3 is garbage? I had no problems with mine – other than not being the brightest of displays. The first thing I do with any watch is to make sure I have the latest updates. I sold mine (as I only have 2 wrists) and got no negative feedback so my experience is more like “nothing special” but “nothing particularly bad”.

  3. Thank you!! I will keep reaching out and see if I can find someone. I’m just not understand why it won’t connect to my phone.

  4. Help, I have no book and can not get my phone and watch to talk to each other. I don’t think I’m using the right app. The watch was a gift and I lost the book can u walk me through setting it up.


    1. Sorry to hear that – by book you mean the instruction leaflet. I no longer have mine – my favourite watches remain the Xiaomi Mi 4 and Samsung Galaxy watch and I only have one available wrist:-) so I can’t advise – maybe someone else who has this watch can?
