The newest offering in the Submersible Collection, the QuarantaQuattro eSteel™, represents the natural evolution of the brand’s ethos with an emphasis on sustainability and ecological consciousness. More than half of the total weight of this watch is made from recyclable materials, with the same physical structure and corrosion resistance as conventional steel. Even the straps, which come in the same color as their companion dial (Grigio Roccia, Blu Profondo, Verde Smeraldo), are made from recycled materials.
