Overview
The Panerai PAM01288 Submersible QuarantaQuattro eSteel Grigio Roccia is a 44 mm diver's watch built around Panerai's proprietary eSteel, a recycled stainless steel developed as part of the brand's broader sustainability programme. Its grey polished gradient dial — "Grigio Roccia" translating loosely as stone grey — carries luminous dot markers consistent with the Submersible line's legibility-first philosophy. The reference pairs this material and aesthetic identity with the in-house Cal. P.900 automatic movement.
History
The Submersible line traces its roots to Panerai's long association with professional diving instruments, evolving from the historic Luminor Marina into a dedicated diver's collection in its own right. The QuarantaQuattro designation — Italian for forty-four — identifies the 44 mm case size tier within the Submersible family, a format that sits between the larger 47 mm references and the more compact 42 mm offerings. PAM01288 was introduced in 2022, representing Panerai's integration of eSteel into the Submersible range as the brand formalised its commitment to recycled and traceable materials. The Grigio Roccia colourway distinguished it within the eSteel Submersible releases of that period.
Notable points

- The gradient grey dial is polished and features luminous dot hour markers, prioritising underwater legibility in keeping with the Submersible line's diver heritage.
- QuarantaQuattro denotes the 44 mm case diameter — Italian nomenclature that Panerai uses consistently across this size tier of the Submersible collection.
- Introduced in 2022, the reference marks a notable point in Panerai's material evolution, bringing recycled-steel construction into an established professional diver format.
