The Luminor Marina 1950 3 Days PAM00422 is a 47mm hand-wound steel watch from Panerai’s Historic Collection. “Luminor Marina” denotes the small seconds sub-dial, “1950” refers to the cushion-shaped Luminor 1950 case, and “3 Days” refers to the 72-hour power reserve of the movement inside.
It was introduced in 2012 and built around the in-house hand-wound calibre P.3001, part of the P.3000 movement family Panerai presented in Florence in 2011 and showed at SIHH. The 1950 case revives the more pronounced, rounded case-band shape of Panerai’s 1950s-era transitional pieces rather than the flatter modern Luminor profile.
Within the range it sits as a regular-production steel Luminor Marina, not a limited edition. It pairs the largest of Panerai’s standard case sizes with a manually wound movement and the vintage-style “aged” lume and gilt hands the Historic Collection is known for.
The dial is black with a matte finish and uses Panerai’s sandwich construction: a lower luminous layer sits beneath an upper disc with the numerals and markers cut out, so the lume shows through the openings rather than being applied on top. The luminous compound is a warm beige “aged” tone rather than white.
Arabic numerals sit at 12, 3 and 6, with bar markers at the remaining hours and a small seconds sub-dial at 9 o’clock. The hands are gilt (gold-toned) and luminous. The dial carries the printed lines LUMINOR over MARINA below 12, PANERAI above 6, and the “L SWISS L” designation at the base of the dial.
The case is the Luminor 1950 form: a cushion shape 47mm in diameter, made of polished AISI 316L stainless steel, with the pronounced rounding at the corners of the case band that distinguishes the 1950 case from the standard Luminor. Dealer and media measurements put it at roughly 17mm thick and about 57mm lug to lug.
The crystal is domed sapphire. The crown is secured by Panerai’s signature lever-bridge crown-protecting device in brushed steel, which clamps the winding crown against the case to seal it. The caseback is a sapphire display back, through which the movement and its power-reserve indicator are visible. Water resistance is 100 metres. The bezel is fixed, smooth polished steel and carries no timing function.
This reference ships on a strap rather than a bracelet. The primary strap is natural, untreated aged-finish calf leather, fastened by a brushed steel tang (pin) buckle inspired by period Panerai buckles. A secondary black rubber (caoutchouc) strap is included in the box, along with a strap-changing tool.
The strap measures 26mm at the lugs, tapering to 22mm at the buckle. The example documented here is fitted on the included black rubber strap. Because the fitting is a simple screw-bar system, the leather and rubber straps are interchangeable by the owner using the supplied tool.
The movement is the Panerai calibre P.3001, a hand-wound mechanical movement developed and produced in-house. It runs at 21,600 vibrations per hour (3 Hz), holds 21 jewels, and uses two spring barrels connected in series to deliver a three-day (72-hour) power reserve. The movement is 6.3mm thick with a diameter of 16┬╜ lignes.
It indicates hours, minutes and small seconds, and carries a linear power-reserve indicator on the movement side, visible through the display caseback. The calibre includes a seconds-reset (zero-reset) device: pulling the crown stops the balance and returns the seconds hand to zero, allowing the time to be set to the second. Winding and time-setting are done at the crown once the crown-protecting lever is opened.
The case, crown-protecting bridge and buckle are stainless steel, with the case confirmed as AISI 316L. The case is polished while the crown-protecting lever device is brushed. The crystal is sapphire, front and back. The dial is a two-layer sandwich unit with luminous fill, and the hands are gilt-toned luminous. The primary strap is aged calf leather; the secondary strap is black rubber.
The overall material makeup is a conventional steel-and-sapphire tool-watch specification, with the finishing contrast between the polished case and brushed crown lever as its main distinguishing detail.
A full set for a current-era example of this reference includes:
Because the reference ships with a second strap and a strap tool, a “full set” listing is only complete if the extra rubber strap and the tool are present alongside the watch worn on leather (or the reverse).
Older version
Newer version
The box generation changed around 2022, partway through this reference’s production life, so an early example and a current example do not carry the same box. A 2024 example is correct with the Gen 2 blue recycled packaging; a 2012 to early-2022 example is correct with the Gen 1 wooden box. A wrong-era or generic box leaves a “full set” incomplete for that watch’s production year.
At 2024 point of sale, the watch carried the Panerai International Limited Warranty of 24 months (2 years) from the date of purchase, valid on condition that the warranty card is signed by an authorized dealer. The warranty is tied to the watch rather than the owner, so it passes to a subsequent owner for whatever term remains. The 2024-era warranty card carries a QR code: scanning it activates certified digital data and enables transferability through Panerai’s Digital Passport system, and registration through PAM.Guard extends eligibility for the warranty extension.

The warranty documentation moved through three formats during this reference’s run: a paper booklet, then a signed physical card with PAM Guard registration, then a QR-enabled card tied to the Digital Passport.
A 2024 example falls in the Gen 3 window and is correct with the QR warranty card and Digital Passport activation. The base term is 24 months from purchase, extendable through PAM Guard to a maximum total of 8 years, so the original 2-year period has expired on early examples and may still be live on recent ones, depending on purchase date and registration. A stamped, dealer-dated card (or its activated digital equivalent) is the primary authenticity document for a full set; a blank or unstamped card is a red flag.
The PAM00422 has been a long-standing steel Luminor Marina reference rather than a short-run model, and it continues to appear in Panerai’s catalogue. Exact current availability is best confirmed directly with the brand.
At 47mm across, roughly 17mm thick and about 57mm lug to lug, this is a large watch with significant wrist presence. The cushion case and the way the lugs curve down help it sit better than the raw diameter suggests, but it is best suited to larger wrists and reads as a deliberate, oversized piece rather than an everyday-discreet one.
The hand-wound movement keeps the case relatively flat for its diameter compared with an automatic Panerai of similar size. The interchangeable leather and rubber straps let the watch move between a dressier vintage-styled look and a more rugged setup. It suits a wearer who wants a bold, mechanical tool watch and is comfortable with a 47mm footprint.
This reference exists in a single core configuration:
Across its production run the watch has been offered in this one build rather than in multiple dial, metal or bracelet variants.
