The measure of a manufacture’s watchmaking capabilities is no longer confined to the sophistication of the movements it produces or the precision of its finishing. As profound environmental challenges demand solutions, attention turn to practices that reduce the ecological impact of every aspect of the watch industry. Panerai is committed to developing strategies for a sustainable future, including reducing waste and promoting reuse of materials. The Panerai Submersible QuarantaQuattro eSteel™ recognizes the critical importance of sustainability goals while maintaining the brand’s established design codes and technical finesse: 72g of the Submersible QuarantaQuattro eSteel™ is made of recycled materials, corresponding to 52% of the total weight of the watch (that is 137g). They will be available exclusively in Panerai boutiques and online at panerai.com.
eSteel™ has the same properties as conventional steel, including identical chemical behavior, physical structure and resistance to corrosion, making the metal a natural companion for the iconic Submersible collection of diving watches. An engraving on the crown protection device and inscription on the dial indicate the presence of eSteel™.
The dial and bezel of the 44mm Submersible QuarantaQuattro eSteel™ match in color. Deep blue, gray and green comprise the moody palette of options.
The Panerai Submersible QuarantaQuattro eSteel™ is original in more ways than one. Never before has the brand used polished ceramic material, but the high gloss surface on the unidirectional bezel is the first of its kind in Panerai history. And the gleaming mechanism frames another standout element: the dial has a polished finish and color gradient that steadily deepens from top to bottom, giving its appearance a surprising dimension.
The P.900 is an automatic caliber that is only 4.2mm thick and supports a date indication and three-day power reserve.
The Submersible QuarantaQuattro eSteel™ is water-resistant to 30 bar (approximately 300 meters). Two straps are included with each watch, both in the same color as their companion dial. The focus of Panerai on sustainability is not confined to eSteel™; the first strap is composed of fabric made recycled PET, while the second strap is made from recycled rubber. A tool that allows interchangeability of the straps and a screwdriver for removing the buckle also accompanies every watch.
