For the past four months, the KOSPET Tank T4 has been on my wrist through some of the most demanding environments in Rio de Janeiro, Brazil — and it has never once let me down.
My routine is not conventional. It includes paragliding over ocean cliffs, scuba diving in the Atlantic, skydiving from altitude, kite surfing in strong coastal winds, and long sailing sessions under intense tropical sun. These are not controlled test conditions — they are real, unpredictable, high-stress environments. And in every one of them, the Tank T4 has proven itself exceptional.
From the moment I take off during a paragliding flight, the dual-band GPS locks in with remarkable precision. During dives, the water resistance inspires total confidence. Under direct Brazilian sunlight, the AMOLED display remains crystal clear and responsive. And perhaps most impressive of all, the battery life consistently powers through multi-day adventures without compromise.
What truly sets the Tank T4 apart is not just durability — it is trust. In extreme sports, trust in your equipment is everything. After six months of saltwater exposure, altitude pressure, impact, vibration, and constant movement, this watch performs as reliably as it did on day one.
The KOSPET Tank T4 is more than rugged — it is engineered for real-world endurance. It represents strength, precision, and reliability at the highest level.
For these reasons, I strongly believe the Tank T4 deserves recognition as a leader in the rugged smartwatch category.
My wife likes this watch and all of its features. Unfortunately, I had to get her another one after a little over a year because it decided to crap out and couldn’t take a charge!
I have had my T-4 for about 2 months , this is an awesome watch and I would highly recommend this and already have.
It is a good wat h but their chargers are always sold out
Out of the box I could tell the T4C is well built and well designed. It feels great on my wrist. Battery life if terrific and the overall operation is quick and efficient. It’s a watch I want wear everyday.
LONG read.
To start off I really wanted to hate this watch. I originally got this watch and had some issues with tech support, made me mad and I sent it back for a refund. They called and apologized and said that they wanted me to try their watch again. I agreed only if they had resolved the problem I initially had, (metric vs imperial units) they promised that is would be resolved, it was. I received the watch and the set up was not user friendly for an old guy, computer is not my native language. I have been using the watch for several months now and I have to say that overall I am impressed, it does have some issues. the integration with the app on my phone could use some improvement but it does work, my main issue is that the weather does not update with my new locations, I travel quite a bit for work and have to remember to change location for correct weather information, also I can read messages on watch but cannot respond to the messages. It tracks my work out activities better than my Samsung watch did when I used it.
I finally had the chance to take the watch diving, this was the main reason I wanted the watch was to have a dive smart watch. I had some difficulty, probably my fault, getting the watch set up to work how I wanted for diving, but after I got everything set up it worked GREAT, it displayed all of the pertinent information that is needed to dive safely, algorithm is fairly conservative, which I liked, after the dive the information quickly syncs with APP and gives great graphic display of dive information of the dive. one of the con's is that the information is small, have to use my bifocal part of my mask, but by being small it allows for all the information to be seen at one time which I like, also at the end of the dive you have to manually "stop" the dive activity, as it didn't stop automatically, it will start when it senses that you descend in the water, once you get it set accordingly. I also like that it is the size of a normal watch that can be worn all the time and not look like a "dive geek". so overall I highly recommend this smart dive watch for anyone wanting a smart watch dive computer combo.
I think a better, more in-depth owner/user manual would go a long way to help getting watch set up and use for different activities
Keeps battery for a while. However, using the flashlight uses up the battery faster. I’ve had this for about 3 years and it still works like its brand new.
Excellent battery life, clear screen, syncs right away. Terrific watch for the money.
great high quality product and beutiful looking
Watch is flawless. Big, bright, beautiful. Easy to use. Has All the features! Battery lasts longer than expected. Just love it!
Un smartwatch robusto, sistema operativo que un smartwatch tiene que llevar y es muy bonito.tuve un problema y el servicio técnico me lo solucionó muy rápido.
I purchased the Tank 3 Ultra2 watch but the band it came with kept coming undone. This replacement works great.
I never received the charger that I bought on the official site.
I bought this watch as a gift for my husband and he is thrilled. He loves the look and all the features.
Received watch 3 days ago love the build and feel especially the large bright screen last 2 watches were more expensive and round screens. So far everything seems good like using the rotating crown to go through menus like the os it's fast and responsive.
Only noticed one con used GPS first time today for a outdoor door walk around local park was slow to lock on but when it did track was really good.Auto detect worked to detect activity
Satisfied customer
I enjoy the large screen and heart rate monitoring. Easier to read the time and messages. In the spring, looking forward to using the GPS capabilities. Easy to set up.
