We’ve seen a range of eye-catching cameras, but none that have taken our breath away quite like Korean craftsman Kwanghun Hyun’s Heartbeat cameras, which uses a Unitas 6497 movement to regulate the Heartbeat’s shutter speeds. 

Hyun is an afficionado in metal craft, but specializes in the creation of pinhole cameras, like the Heartbeat. Pinhole cameras have a tiny aperture, and normally no lens. Pinhole cameras are essentially a box with only a tiny hole that lets light in. The aperture is a small hole that allows light to pass through and projects the image onto the opposite side of the box, inverting it. Timing is crucial when using pinhole cameras, due to the low light that comes through the hole.

The cross-over between the camera and the watch is intricate and quite frankly, genius. Long exposures ensure that the photos come out better, but the Heartbeat is both unique and useful in that it uses a watch movement to regulate the camera shutter speed, controlling the amount of time the shutter is open, and allowing the user to time how long the shutter is open. The design obviously reflects the meticulous mechanisms of a watch, with components like the crown exposed, and a steel finish.
