Overview
The Panerai Submersible QuarantaQuattro eSteel Verde Smeraldo (PAM01287) is a 44 mm diver's watch built from eSteel, Panerai's proprietary recycled stainless steel developed in partnership with a specialist European steelmaker. Its polished green gradient dial — named for the Italian word for emerald — gives the piece a distinctive chromatic depth that sets it apart within the Submersible family. The calibre P.900, manufactured in-house, powers the watch with a movement architecture well suited to professional diving use.
History
Panerai introduced eSteel as a sustainability-oriented material initiative in the early 2020s, incorporating post-consumer recycled steel into case construction without compromising the mechanical properties expected of a serious dive watch. The Verde Smeraldo variant, released in 2022, represents one of the more visually expressive expressions of the QuarantaQuattro case — a 44 mm format that sits at the traditional heart of the Submersible line. Collectors have noted the dial's gradient finish as a departure from Panerai's historically restrained palette, reflecting a broader industry trend toward chromatic experimentation in sports watches.
