Remember darkrooms, developers, red lighting and chemical baths? Back before you could take pictures with your phone, you had to use a type of camera that required rolls of "film." Light would be let through the lens of the camera and would coat the film, capturing an image that appeared on the other side of the lens. Then you'd have to go into a darkened room (called a "darkroom") to open up the film cartridge and mix it with chemicals to create a film negative. Stick with us here. Then you would use equipment to shine light through the negative onto photographic paper, which was then put through a series of chemical baths. You would need to time these processes in order to properly develop a photograph, and to time them, you'd need a timer. One that looks a lot like this watch. Our watch brings it all back for photography enthusiasts. Glows in the dark.
