Watch the Pinhole

Kwanghun Hyun is a Korean artist who's made a pair of mechanical-watch based pinhole cameras. They're more impressive as creations then actually cameras, since they are far more precise and overbuilt then a pinhole camera needs to be, with no improvement in the actual pictures taken. The intriguing part is that the timing mechanism is a Unitas 6497, one of the modern workhorse manually-wound calibers. On his Heartbeat 1, the movement is basically unchanged, with a series of tiny leaf springs handling the stop and stop functions from the watch. For the Heartbeat 2 he reorganized the wheels of the caliber on custom baseplates to fit the camera case better.
