OPEN HAM WATCH v. 1.0 - IK8YFW - 2015
This is an OpenSource project based on Arduino platform, for building a smart watch with some interesting functions: OLED Display, clock RTC, Satellite pass prediction routine, Moon phase routine, multi Alarms user and Satellite approaching alert, power safe, DST, Timezone and dual time.
This watch with use a Monochrome OLEDs based on SSD1306 drivers 128x64 size display using I2C to communicate.
The compiled code size is about 31kb, you need capable arduino device with at least 32kb of memory. All the Arduino Nano card will work well.

NOTE: This software use the Adafruit SSD1306 and GFX dispay libraries to connect the oled display. These libreries can be downloaded from Adafruit site.
TO build the software you must download the SSD1306 and GFX libray from adafruit:
