It would be enough if this beautiful Steampunk watch over at Instructables just kept time, but it also has the mechanical retracting iris that makes this watch a piece of art. The YouTube video of it in action is below, but it’s safe to say the thing is absolutely gorgeous.

Best of all, since it’s Instructables, you get to see how the thing is made, from start to finish.
