I would have been impressed with anything functional, but to me this actually looks nicer than the vast majority of commercially produced smart watches. Awesome!

The Samsung smart watches look really nice to me, I don't know how decent they are in real life though since I don't own one.

Just got a Galaxy watch Sunday. So far I like it a lot. The rotating bezel is by far the best feature compared to other smart watches.

Looks good. Time for you to do a Kickstarter!

Right now they're very gimmicky, Apple watch has a much better app ecosystem

Here’s the Reddit thread with more feedback from the creator[0]. Amazingly gets a week between charges[1]

This is nicely done, beautiful aesthetics. There are multiple phases (HW, SW, Mechanics) which would be impressive enough on their own. Kudos!

Love the little gifs to explain how it's done, especially the stenciling of the PCB.

I'm curious, how/why did you choose the DA14683 chip?

Quoting the OP from the reddit thread:

"I picked the MCU for a couple of reasons:

-Very low power transmit/receive for the bluetooth (-Cheap

-High speed on the SPI bus. The display writes are limited by the SPI bus. It requires a 9-bit word (additional bit is used for data/command). So being able to run the SPI bus at 48MHz is clutch.

-Has PMIC integrated into chipset. I don't need to include additional circuitry for a buck-boost regulator or a lipo charger since the dialog part has it all built in!

-Cheap"
