Watch V2.0 isn’t just another smartwatch. It’s a canvas for creators, developers, and enthusiasts. This fully customizable E-Ink smartwatch is powered by an ESP32 chip, offering Wi-Fi and Bluetooth LE connectivity, a 1.54″ e-paper display, and complete open-source flexibility. It’s a unique wearable platform designed for personal hacking, prototyping, or stylish functionality.
Equipped with a crisp 200×200 pixel e-paper screen, Watch V2.0 displays clearly even under direct sunlight. It sips power slowly—giving you 5 to 7 days of battery life on time-only mode, and 2 to 3 days with regular Wi-Fi API calls. Between screen updates, power usage is nearly zero.
You can wear it out of the box or 3D-print your own case using included STL files. Add external sensors via accessible IO ports, such as heart rate, GPS, or SpO2. Program it using Arduino, MicroPython, or ESP-IDF. It’s not just a watch—it’s your own portable playground.
Whether you’re into retro digital designs or cutting-edge experimentation, Watch V2.0 empowers you to build your perfect wrist companion. It even features multiple watch faces, mini games, and WiFi/BLE-based API integration (weather, Spotify, etc.). It’s modular, durable, and designed to evolve with you.
Customizable E-Ink Display – Always-on 1.54″ e-paper screen with 200×200 resolution, great for low-power, high-contrast use.
Open Source Firmware – Compatible with Arduino, ESP-IDF, Zephyr-RTOS & MicroPython.
Modular Hardware Design – Add sensors like heart rate, GPS, or temp with onboard GPIO.
Wi-Fi & Bluetooth LE – Connect to weather APIs, BLE devices, or your own IoT ecosystem.
Long Battery Life – 5–7 days without Wi-Fi, 2–3 days with live updates.
3D Print-Friendly – Design your own case or use ready-made STL files for full personalization.
Built-in Accelerometer – Gesture control and motion wake supported.
Perfect for Developers – Includes USB-to-serial adapter for easy flashing and debugging.
We believe technology should be open, accessible, and fun to modify. Our mission with Watch V2.0 is to empower creators—from students and developers to engineers and IoT explorers. Born out of the maker community, this smartwatch isn’t just wearable—it’s programmable, personal, and purpose-built for experimentation. We’re proud to deliver quality hardware with complete source code, documentation, and 3D design files—because the best technology invites you to make it your own.
Q: Can I program Watch V2.0 without advanced coding knowledge?
A: Yes! The watch supports Arduino and Micropython, both of which are beginner-friendly. Plenty of examples are included.
Q: How long does the battery last?
A: It lasts 5–7 days on timekeeping mode and 2–3 days with WiFi updates. You can extend this by customizing its sleep/wake behavior.
Q: Can I use my own 3D-printed case?
A: Absolutely. We provide open-source STL files, and the watch is designed to support custom straps and enclosures.
is an e-paper watch with open source hardware and software. You can wear the PCB watch body directly, or you can use 3D printing equipment to print the case and strap for personal customization.
This is not only a unique timepiece, but also a wearable development platform with reserved IO ports, allowing users to connect various sensors, such as heart rate and blood oxygen sensors.
Watch’s e-paper display provides clearly visible images in bright sunlight and does not require power between updates. The display has a pixel of 200×200 and displays in monochrome.
Watch supports WIFI and Bluetooth LE connections, and can connect to Internet APIs (such as weather, news, traffic, maps, Spotify, etc.) and devices that support Bluetooth LE.
Considering the needs of makers/hackers/tinkerers, we chose ESP32 because of its large community and support for various development options (Arduino, Micro python, ESP-IDF, Zephyr-RTOS, etc.)

Battery life
Watch wakes up every 60 seconds, checks the accelerometer, real-time clock, and updates the electronic paper display screen with the latest information. Some watch faces also turn on WIFI to get weather data..
The battery life of the Watch is 5-7 days when only keeping time, and 2-3 days when acquiring data over WIFI. These numbers can be extended with further optimization (e.g. sleeping during non-working hours, waking only on motion/tilt, etc.)
Note
Please be sure to select hardware version V2.0 when flashing
Wireless Network Settings
1. Click Set Up WIFI in the main menu of your watch.
2. Connect to the “Watch App” WIFI from another device (such as a mobile phone or computer/laptop).
3. Open 192.168.4.1 in your browser. On an iPhone, this page will open by itself when connected to WIFI.
4. Click on “Configure WIFI”.
5. Enter the SSID and Password. (Note: the SSID may be pre-filled from the network listed at the top of this screen)
6. Click the “Save” button and wait.
7. If the connection fails, the watch will display “Setup failed and timed out!” otherwise it will display the local IP address and SSID of the connected network and confirm it.
