The Panerai Luminor Power Reserve Automatic Acciaio PAM00090 is a 44 mm steel automatic watch built on the Luminor case, with a small seconds display, a date, and a linear power reserve indicator added to the standard Luminor layout. It sits in the Luminor collection as a steel, automatic, function-added alternative to the time-only Luminor models.
The reference uses the cushion-shaped Luminor case and the patented crown-protecting bridge that clamps the winding crown. It carries the asymmetric dial arrangement created by placing the small seconds, date, and power reserve indicator around a single dial.
Panerai produced the PAM00090 from 2001 to 2016. It was discontinued in 2016 and replaced in the collection by the PAM01090. The example documented here is dated to 2009, which falls inside that production window.

The dial is black with a flat finish. Hour markers are luminous batons, with luminous Arabic numerals at 12 and 6. The hands are luminous stick hands. The layout is asymmetric: a small seconds sub-dial sits at 9 o’clock, a linear power reserve indicator sits between 4 and 6 o’clock, and a date window sits at 3 o’clock under a magnifying lens.
The power reserve arc is graduated toward a 40 mark and shows how much running reserve remains as the mainspring winds and unwinds. Printed dial text reads LUMINOR PANERAI with Automatic below the 12, Power Reserve above the 6, and SWISS MADE at the base of the dial flanking the 6 numeral.
The overall face is built for legibility, with high-contrast luminous furniture on a plain black ground and no printed minute track interrupting the markers.
The case is a cushion-shaped Luminor case, 44 mm in diameter, in polished stainless steel. The defining external feature is the crown-protecting bridge at 3 o’clock, a hinged lever device that closes over the winding crown and locks it down against the case.
The bezel is smooth polished stainless steel, fixed, with no timing or measuring scale. The crystal is a slightly domed (cambered) sapphire crystal with anti-reflective treatment. The caseback is a solid stainless steel screw-down back.
Water resistance is rated to 300 meters. The lug width is 24 mm.
This example is fitted on a black Panerai rubber strap with molded branding and a ridged surface, on a 24 mm lug width. It is secured by a stainless steel folding (deployant) buckle with a double push-button release.
The reference was also supplied on leather and crocodile straps over its production run. Full sets frequently included both a rubber strap and a leather strap together with a strap-changing screwdriver, so the watch could be swapped between the two.
The strap attaches to the Luminor case with screw-bar lugs, which is what the supplied screwdriver is used for.
The movement is the Panerai caliber OP IX, an automatic movement based on the Valjoux 7750, stripped of its chronograph works and fitted with a power reserve module. It runs at 28,800 vibrations per hour, carries 21 jewels, and provides an approximate 42-hour power reserve. It is COSC chronometer certified.
Functions are hours, minutes, small seconds at 9 o’clock, date at 3 o’clock, and a power reserve indicator between 4 and 6 o’clock.
Setting and winding are done through the crown at 3 o’clock. The crown-protecting bridge is unlatched first, the crown is then used to wind the movement and set the time and date, and the bridge is closed and clamped again afterward to seal the crown.
The overall material character is a polished steel tool-watch build with a sapphire crystal and a rubber strap, using no precious metals or ceramic.
A full set for this reference and era typically includes:
Because the OP IX is an ETA-based movement, the chronometer paperwork for this reference takes the form of a separate external COSC certificate rather than certification printed inside the warranty booklet. A complete set should therefore carry both the warranty card and the COSC certificate.

The PAM00090 used the pearwood presentation box throughout its retail life, across three generations of the same box style. A 2009 example belongs to the 2007 to 2012 updated pearwood box with the revised interior.
A Panerai service box on this reference is a replacement rather than the era-correct retail box. A full set is judged against the pearwood box that matches the watch’s production year, so a service box or a wrong-era pearwood box leaves the set short of era-correct even when the box is genuine Panerai.
At the time of sale, the PAM00090 carried the Panerai International Limited Warranty of 24 months (2 years) from the date of purchase, valid once the warranty document was completed and stamped by an authorized point of sale. The chronometer certification was documented by a separate COSC certificate supplied with the watch. For a 2009 example the warranty took the form of a plastic warranty card, the format Panerai used from 2008 onward, rather than the earlier paper certificate booklet.

A 2009 example falls in the 2008 to 2016 window and shipped with the plastic warranty card rather than the earlier paper booklet, together with its separate COSC certificate.
The original 2-year warranty on a 2009 example has long expired, and the reference is outside the two-year eligibility window of the Pam.Guard 8-year extension launched in November 2019. The stamped and dated warranty card and the COSC certificate remain relevant as original sale and authenticity documentation for a full set rather than as active coverage.
The PAM00090 was discontinued in 2016 and replaced in the Luminor Power Reserve line by the PAM01090.
The 44 mm cushion case gives the watch a large footprint on the wrist, and the crown-protecting bridge adds visual and physical bulk at the 3 o’clock side. It wears as a full-size watch and suits medium to large wrists.
The 24 mm strap width matches the broad case and keeps the proportions balanced. On the rubber strap the watch is a daily-wear steel automatic; on a leather strap it takes a slightly dressier character while keeping the same case presence.
This is a watch for a wearer who wants a full-size Luminor with added functions (small seconds, date, and a power reserve readout) rather than the time-only layout.
Across its 2001 to 2016 run the PAM00090 held the same core build: a 44 mm polished steel cushion case, a black dial with luminous baton markers and Arabic 12 and 6, and the automatic OP IX movement. What changes between examples is the strap and buckle fitment and the production-year dating.
