The design was inspired by a prototype that was the foundation of the photovoltaic eco-drive but was never commercialized, and has been brought back to life by incorporating the latest photovoltaic eco-drive technology.
The case shape, distinctive six-part dial design, and three-dimensional indexes are reproduced using handwritten drawings from the time as reference.
The unique designs of the time, such as the smooth curves of the case and the tall cut glass windshield, give it a fresh impression.
The blue dial, which reproduces the design prototype, brings back the masterpiece of the engineers of the time to the present day.
