This is the µWatch (uWatch), the world’s first DIY scientific calculator watch. The uWatch is programmable and it is built entirely from ff-the-shelf components.
The picture above is the second prototype, you may also want to see the first prototype after the break.
The second prototype is the one you see presented here, and it looks fairly professional indeed! A trial wearing it for a few days had people asking me were I bought it, they thought it was a commercial watch. Even when I showed it to other engineers they were surprised I built it myself, and were even more surprised when they found out it used all off-the-shelf bits.
