The Artra Designs Camera One (C1), inspired by the art of photography, transcends conventional boundaries with two patents. The dial incorporates the structure of a camera aperture. Turning the crown on the upper left corner dynamically opens and closes the aperture blades, revealing the translucent film. Admiring the rhythm of the movement, one feels as if transported back to the romantic past of film photography.

The bezel is designed based on the classic "Sunny 16" principle. The luminous pearls indicating the F-number correspond to ISO and shutter speed. This universal principle in photography allows photographers using film to align the luminous pearls with the aperture value at different film speeds, and quickly match the ISO indicated below the inner bezel to the appropriate shutter speed. This allows for simple metering, integrating photographic parameters into the time-reading process and seamlessly integrating timing with the professional logic of photography.

The depth of field scale on the left and the rotor on the back, featuring the iconic image of "Horse in Motion," the first moving image ever taken by Muybridge in 1878, pay tribute to the history of photography in every detail. More than just a timekeeping tool, it embodies the art of photography on the wrist—encapsulating the inspiration and essence of photography within its compact dial. Every glance at the time feels like a touch of photographic art, embarking on a journey of photographic exploration on the wrist.
