      Great watch for teens

      Just purchased and assembled watch with 13 year old son. Had a great time teaching him soldering and components. Very easy build and code is already uploaded to IC chip, making it plug and play. Code programmed for 24 hour time, but code is provided to modify clock mode and brightness. Tip: Do NOT over tighten plastic screws, acrylic cover can crack.
