This material is also low-density, making it feel as light as aluminum.

The watch can generate enough energy to provide 44 hours of autonomy. The watch also has a shock-absorption and provides maximum protection against abrasion.

The dial is made of carbon fiber and has Arabic numerals 6, 12 and indexes that are filled with luminous material. The hour and minute hands have been coated with the same material for better visibility in low-light conditions.
