Panerai Submersible QuarantaQuattro eSteel

Panerai presents Submersible QuarantaQuattro eSteel, a series of diving watches certifying the brand’s commitment towards a sustainable future, including reducing waste and promoting reuse of materials.

The Panerai Submersible QuarantaQuattro eSteel™ maintains the brand’s established design codes and technical finesse.

72g of the watch is made of recycled materials, corresponding to 52% of the total weight of the watch (that is 137g). An engraving on the crown protection device and inscription on the dial indicate the presence of eSteel™.

The brand is now offering three versions of the 44mm Submersible QuarantaQuattro eSteel™ watch: Deep blue, gray and green.

Finished in Deep blue, gray or green, the dial has a polished finish and color gradient that steadily deepens from top to bottom. The watch is mounted with a unidirectional bezel and the color of polished ceramic bezel-insert matches with that of the dial.

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 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.

The Submersible QuarantaQuattro eSteel™ series is available exclusively in Panerai boutiques and online at

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.
