This is a great ATtiny85 watch that uses a SSD1306 OLED display and is powered by a CR1220 battery.
Today core subject, ATtiny85. Someone suggest me to use SOIC version to reduce the watch size and I found the coin cell mAh calculation method will count the battery voltage down to 2.0 V, so this watch require a low voltage version MCU to keep it stable. So I have ordered an ATTINY85V-10SU. (much expensive $_$)

Matthew Filipek from Cornell Univercity has build a nice smart watch with 1.7 inch touch screen, SD card, Bluetooth module and various apps.
One of the main inspirations for this project was Jared Sanson’s implementation of a DIY smartwatch (REF 0). With several design iterations, he was able to produce a watch in a very small package that can communicate with a PC via USB HID, features an OLED display, and has support for an accelerometer. As my project was to be completed in the span of a mere month, several of the components I got were purchased for their ease of use rather than their compactness.

陳亮 @ instructables.com shows us his ATtiny85 OLED display build on a breadboard:
This instructable show how to use an ATtiny85 to create a tiny watch core that can run over 1 year before recharge or replace battery.
The instruction to make the watch case may be in next instructable.
I have made a few Arduino watch before, but I found the watch using ATmega boards or ATmega chips are a little bit too big to wear. So I would like to make it with a smaller chips.

Benjamin Blundell has been working on his DIY smart-watch:
I have an issue with smart-watches. Watches in general fall into one of two categories: a tool to tell the time, or a fashion statement. Increasingly, I believe the latter category is larger than the first. With the advent of the iWatch, Pebble and the like, fashion and making a statement has moved into technology. It’s not quite a new thing but nevertheless, it’s something I’m not too fond of. My solution? Make your own smartwatch.
There is a precedent for this. Steve Wozniack sports a pretty fly nixie tube watch which he made himself. It’s pretty cool, but also a statement of sorts too. I’ve been meaning to up my game with electronics anyway, so I’ve been working on a few initial prototypes.

In today’s technology, especially electronics have come a long way, to the point that today can make projects a few years ago were very complicated to implement, thanks to these technological advances are now able to design and implement our houses projects.
and through this article I come to show you my new project, which consists of a wristwatch, so I called Arduino Watch Sport.

What’s inside the new Pebble Time Smartwatch?
Dave does a teardown after taking it through the torture test, and gives it a close up view with the Tagarno microscope.
How easy is it to disassemble and replace the battery?
How much do the components cost?
What is the manufacturing quality like?
How does the Bluetooth antenna work?

Hello! Welcome to another Other Machine project tutorial! I’m Sam DeRose, a former Other Machine Co. Summer Intern. I created The Nerd Watch last summer while working at OMC.
The Nerd Watch displays the time in binary when the button is pushed. The watch shows the hour and minutes by flashing two LEDs in sequence to represent two 4-bit binary numbers (in big-endian format). Here’s a great description of how to read binary numbers.
In this Instructable, I’ll show you how to build a Nerd Watch from scratch with a few electronics components, and an OMC Othermill.
This Instructable presumes you have previous experience working with surface mount electronic components, and that you are no stranger to a multimeter or soldering.

F*watch is a fully open electronic watch project featuring an integrated GPS receiver.
The development started at CERN as an after-work project to make a special present for a retiring colleague who likes hiking and timing.
The full design (electronics, mechanics and software) is available under free licenses and the design is exclusively made with free tools.
