Company history
Valbray co-founder Côme de Valbray was, and is, an enthusiastic photographer who had used Leica Cameras for many years. He was inspired to create a watch with a Shutter (photography) diaphragm similar to the cameras he was using. After two years of development created a watch dial that the brand calls "Oculus", which is composed of thin blades that open and close by rotating the bezel.

Patent
The "Oculus" dial system is composed of 16 very thin 0.05 mm blades operated. Rotating the bezel transforms the dial from being completely closed to completely open and vice versa. The invention was awarded a patent in 2010.
