Hammerhead Hands

When you design watch hands, it's not only a case of aesthetics.  There are physical constraints, too, such as weight and moment of inertia.  But my big fight is with a thing called unbalance - the extra energy required to push it "uphill" when it's fighting gravity at the 9 o'clock position.  This is the dominant constraint for us, especially on the minute hand.

There is something that can be done to help.  Give the hands tails.  Currently we're experimenting with hammerhead hands - see the photo.  It allows us to make the hands just that little bit longer.  It also gives us a relatively unique look.  As often happens, the constraints you face end up improving the look.

Let me know what you think.
