LED Watch 3000 is a digital watchface that comes with several seven-segment display styles and color choices. It is an Android-only application that works on Android 9.0 and above. The watchface displays the time of day with seconds, the day of the week, the date of the month, and the battery percentage.

One of the best features of LED Watch 3000 is its ability to change colors. You can change the color of the watchface by tapping twice on the screen. It also has multiple watchface styles that you can switch between by tapping thrice on the screen. These styles include a modern LED watch style, an LCD watch style, and a vintage LED watch style.

Please note that this watchface will not work on Samsung Gear devices running Tizen but should work on the Samsung Gear Live, which runs Android Wear. The developer, Darren Embry, provides the source code for this application on GitHub.

If you are looking for other watchface styles, the developer has also created Pilot Watch 3000 and Cockpit Watch 3000, which cater to different preferences. You can find all of the developer's watchface styles on their website.
