I received this watch today, and as soon as I unboxed it, I was truly impressed. The build quality is outstanding, the calling sound quality is excellent, and all of its features are amazing.
I’m very happy that I purchased this watch from Olevsstore.com. The build quality exceeded my expectations, and I really like all of its features.
I highly recommend this watch. If anyone is thinking about buying it, you can purchase it with complete confidence. Considering its price and the quality it offers, it provides incredible value for money. It’s truly an amazing product.

The experience has been nothing short of five stars. If I could give more, I absolutely would. Tony is a fantastic guy who was incredibly helpful throughout the entire buying process on his website. I purchased two watches, and I'm delighted with both of them. They look absolutely stunning, the quality is excellent, and they far exceeded my expectations. Honestly, a $100 watch looks like it could cost $50,000. The craftsmanship and attention to detail are truly impressive. I was also very happy with the fast shipping and the outstanding customer service. From start to finish, the experience was smooth, professional, and enjoyable. I would definitely recommend this shop to anyone looking for a high-quality watch at an incredible value. Thank you, Tony!

Was very surprised - saw a review on Reddit for the e400 and so on a whim I tried it out. Received in exactly 2 weeks. Now that I've charged it and tried it out, it's awesome! The blood glucose exactly matches my meter when I pick my finger! The o2 sensor works great! And the ecg also works great! Absolutely could not recommend this smartwatch any higher - you won't be disappointed! & I did not / will not receive any thing for this review!

Beautiful product, fast delivery. I only received it recently, but it still works. Since it is an automatic and thus a mechanical watch, time deviates a bit but that is normal. To take into account: the number of years only goes so far, and the date (right dial) is not the easiest to read. But hey, that's something you can see on the picture yourself too. The watch hasn't been wet yet (and as with very watch, I intend to keep it that way), so I can 't speak of waterproofness. Only sad it says that its a chronograph on the dial, because it isn't a chronograph. Left dial shows the day, the below dial shows the hours (24) and in the upper part of the dial you can see the sun and the moon move along. The right dial - a bit hard to read, see above - shows the date. All in all, at this point in time (pun intended) really satisfied with the watch. It is beautiful and does what is has to do, showing the time.


Edit: please note: buy the watch at the correct company: Olevsstore.com! As mentionned on their website, all the others are fake!!! So don't buy on Aliexpress, Olevs.com, or wherever you can find them. They advertise it on their website too, but sometimes a search shows you the fake ones first!!!
Edit 2: one small think I don't really like is that there is no micro-adjustment on the bracelet like with some other watches. Luckely for me, when I removed the necessary links (with the provided tool!!) it fits without needing the micro-adjustment. But others might need the micro-adjusment. The provided tool worked for taking the links out, but is is still a plastic tool, so I had to resort to something else to get finisch it decently in the end. Nonetheless, a tool was provided and that's something you don't get with other brands as far as I'm aware of.
