KOSPET Tank M3 Ultra Smart Watch with GPS, 5ATM Waterproof, Compass, Altitude, Air Pressure, Extra Large Battery, Full Stainless Steel, Bluetooth Call, 1.96'' AMOLED Always-on Display, AI Voice

Good watch. Im very hard on my watches due to my job as a lawn tech. This watch has held up nicely. The battery life is excellent compared to my Samsung. The display is easy to read and you have several choices. If you are looking for a watch you are going to beat up this The one for you.

I previously had the M2 Tank watch and when the time came, I upgraded to the M3 Tank. This is a great watch. I use it for everything. I can read my SMS messages and Teams chat, track my sleep, take calls, track steps, weather, compass, and even check my blood pressure. Everything works great and the battery life is beyond amazing. The M2 has great battery life but I quickly realized the M3 has even better battery life. To prove it, I fully charged it on March 31st and here it is April 30th and I'm still at 19 percent battery! That's incredible! Well worth the cost. I highly recommend this watch.

Be aware. M3ultra does not have route back feature like the t3 ultra 2 does. Cannot back trace on my recorded routes. What i bought it for to take on hikes. Not stated in the ads, only found out in a kospet article after i chose m3ultra because of larger display. Both state they have stand alone gps. Limited at best, no route guidance. No gps coordinates. Only has compass and route tracking. Would have been easy to add functionality via hardware flash. Customer service will not exchange my m3 ultra for t3 ultra 2. My last kospet tank

To me this is a great looking watch. Connecting and syncing was simple. Tracks activity well. Shows walks and runs on map using GPS. I do wish it was Google maps as you could switch to satellite view. A little buggy when it comes to showing messages etc on the watch as it sometimes mixes up the 'header' and message body. Love the 4 buttons vs a dial to switch between menus etc. Wish it has additional watch faces. I did have one issue when the watch face was totally dark one morning when I went to take it off the charger. Had to do a "Manual Upgrade" to the system. This happened two days ago but seems to be functioning fine now. A good functioning watch at a great price. Would recommend.

Lots of insightful information and Great battery life. Easy to use if you dont mind sharing your personal information.

This watch is almost perfect. DON'T trust the the waterproof abilities of this watch. It has failed me twice.The first time I had the Tank M2 and after a swim in a 6ft pool the screen stopped functioning and eventually died. Was very happy to be refunded under warranty from Kospet almost a year later.I used the refund + $$ to buy the Tank M3 (of course it made sense to upgrade so I spent more money). That was September 2024. Now in April 2025, once again took a swim in a 5ft pool and the watch glitched for 24 hrs even though I have tried to turn it off and now refuses to turn on or even charge. I have written to Kospet to request a refund under warranty. I love this watch but the 5ATM is untrustworthy to say the least. Ideally, I should rate this as a 1, maybe a 2 star but the watch is great if you DON'T swim with it. You could get it wet or dunk your hand in water with no worries but I can't recommend leisurely swimming with it. Will provide an outcome as soon as I get a response.*UPDATE * - Kospet warranty supported by Amazon customer service continue to be the silver lining of this upsetting situation with the watch. A full refund was issued and received. Did not initially upgrade the stars because making a watch waterproof should not be rocket science in 2025, however, Kospet did reach out to me again to ensure my issue was addressed. So based on 1. The high level of customer service, 2. How much I do love this watch and all its functions, I am giving it 3 out of 5 stars.

Good watch, battery lasts days between charges sometimes I don’t charge it for a week! The watch can take a beating, worn while working and never cracked the screen. I like the screen size and ease of using it. I use mine with an iPhone.

Great watch. Customer service is excellent! My son somehow lost the charger and I contacted them and they sent a new charger free even though it was our fault
