Rogbid Tank M5: The new AMOLED smartwatch promises extensive sensor technology and phone functionality, raising doubts.

Tank M5: New smartwatch with AMOLED and phone functionsTank M5: New smartwatch with AMOLED and phone functions

The Rogbid M5 is a new smartwatch that is advertised as being packed with features at a relatively affordable price. The display is based on AMOLED technology and ensures powerful color reproduction.

Rogbid has launched a new smartwatch called the Rogbid M5, which is yet to be officially released outside of China. Therefore, international buyers must switch to direct import, but delivery is not guaranteed for all countries.

The watch is equipped with a 1.43-inch AMOLED with 466 x 466 resolution, ensuring high clarity. The smartwatch is also said to be partially made of zinc alloy to ensure high durability. The range of functions is extensive, including the possibility to control music playback from a paired smartphone. It also has a microphone and speaker, so you can make phone calls directly from the smartwatch.

Rogbid advertises a variety of health features. In the best case scenario, heart rate and pulse oximetry measurements can be accurate, but when it comes to actually measuring other parameters, I think precise monitoring is nearly impossible. For example, it should be possible to measure blood pressure and blood sugar levels purely optically, which would represent a major breakthrough in optical sensor technology and would pose significant challenges for manufacturers of such medical products.

Analysis of sleep quality and sleep duration is relatively realistic, which can be done by monitoring recorded movements during sleep. Stress levels should also be measurable. The watch, which is about 12mm thick, is equipped with a 400mAh battery. As usual, charging takes place via a magnetic plug.

I have been a journalist for over 10 years, mostly in the technology sector. I’ve worked at places like Tom’s Hardware and ComputerBase, and have been working at Notebookcheck since 2017. My current focus is on single board computers such as mini PCs and Raspberry Pi. Potential. Plus, I have a soft spot for all kinds of wearable devices, especially smartwatches. My main job is as a laboratory engineer, so scientific contexts and the interpretation of complex measurements are no stranger to me.

Growing up in regional Australia, I was first introduced to computers in my early teens after breaking my leg during a soccer game, temporarily forcing me to live indoors. Soon after, I started building my own systems. I moved to Germany in 2014 to study philosophy and anthropology and currently live in Germany. I am particularly fascinated by how computer technology has fundamentally and dramatically transformed human culture, and how it continues to do so.
