    It looks like a watch and comes in a handy plastic case like a wrist-watch... But in fact its a development platform for ESP32 applications with color-display and acceleration sensor and its own Lipo inside. Arduino code with ESP32 libraries should fit in. So its the perfect platform for standalone ESP32 devices such as Smarthome Status, OBD2 Car Displays etc. And perhaps - some people might even use it as a watch... Great little hardware, nicely made - good value!

    A tinkerer's watch. You'll need to do some work yourself to make this into the watch you want. Hardware is nice, though there are concerns about the longevity of the bands and rear cover. There is an active development scene on GitHub. The documentation needs a bit more work as it is pretty sparse. If LilyGo would release a schematic that would enable a greater understanding of the hardware. As for modifications: There's almost enough space to install Qi wireless charging in the back of the device. There are two gpios, and 1 gpi usable on the ESP32 itself, and the Axp202 pmu has two open drain gpios free. You'll need to do some micro soldering to get at these though.

    The supplied software is extremely basic but the LilyGO development library code ( is being actively maintained and expanded by an ever growing number of developers. The watch has an amazing backlight that makes the screen visible even in the strongest sunlight. The strap is a unique design that takes a bit of getting used to. I have started to develop my own watch software with many new features and a huge wish list that I will be adding when I can. The photo in my review is with version 0.2 of my software loaded.

    It's a nice, cheap watch. With a little effort, one can make it a nice useful item for everyday life, which can last for four days without charging. I wrote code for it to display a set of Back-to-the-future watchfaces. More details and download/installation instructions re posted on my blog:

    You will love this watch if you like to have something custom and is arduino based. Is an ESP32 and you can program anything you like. Just download from the github and learn from the example. My button fell off from the watch when received but I had fixed it back with some thin copper wire. Hope the other version wont be like that. Other than that I am very satisfied with the watch.

    definitely another good product from lilygo! the watch looks very well made. it has a charging/programming micro usb port and a multi function button, touch screen, etc. unfortunately it hasn't got the heart beat sensor, I hope they'll add it in another version

    Very funny for nerd programmer as me, totally unuseful as is for non programmer, so this must be clearly understood before buy. The battery has low authonomy, but it's easy swappable with easy foundable spares. Good display, wifi, general manufacturing. Highly recommended

    The watch is pretty cool. There are quite some resources out there on how to program it and also some custom solutions available. For programmers and tinkerers definitely worth it. Mind though that you really need keep thinking about battery consumption when developing for it.

    Looks ok, but it is usable as-is. Only buy if you want to tinker with the software. But for tinkering with the software... it is really cool! It has a bunch of useful IC-s, and all of them (maybe except the axp202) are well documented online. I'm using it with Micropython.

    From order to receiving the watch 9 weeks. This ESP32 based smart watch is a good starting tp makers and tinkerers. The software is very basic, but i am porting my own apps to it shortly. The battery is npt going to last long, only short operating times recomended. I think it is wort the price :)
