How to Build the Watchy E-Paper Smartwatch

The Watchy Kit includes:

• Assembled circuit board
• Battery
• Double-sided tape
• Wrist strap
• Injection-molded plastic case
• E-Ink display

What’s not included is a micro-USB cable, which you will need to have in order to charge and connect the Watchy to a PC.

While the package for Watchy does come with instructions, they’re merely pictures. I recommend downloading or bookmarking the Getting Started guide on the Watchy website. This includes all information you might need in order to assemble and run Watchy.

The battery will easily plug right into the shown slot on the circuit board. Once you feel confident that the battery is connected, move on to the next step.

Connect the display screen to the FPC connector. The shiny gold pins on the ribbon cable should be facing up, and the ribbon cable goes through the PCB slot like in the image above. Make sure to lock the ribbon in with the small locks located on the sides of the FPC connector.

While the instructions say to not use the included tape, I do recommend using it for those who are new to DIY tech. The case that will go around the Watchy components will be secure, however, it’s difficult to keep everything in place all at once. Thus, don’t be afraid to use the double-sided tape!

The screen should be placed so that it doesn’t extend above or below the strap holes; see the graphic below.

Once you’re confident in your screen placement, you’re ready for the case!

We’re going to deviate from the directions here, but don’t panic. Start by aligning the top part of the case around the display, as it needs more manipulation than the bottom.

Place the small plastic button pieces into their slots on the sides.

Finally, snap the bottom half of the case into place, making sure that the USB port and buttons are snug. It will take some finagling to get everything into place (particularly the battery).

Pull the pin on the strap inwards (to the left) and align it to small holes located on the top and bottom of the case. The pin will snap locked once it’s in its proper place, the pin lock will be outwards (to the right) when complete.

You are now ready to charge, setup, and use the Watchy, e-Paper smartwatch!
