Is your Luminor Due
the real deal?
The Panerai Luminor Due is the refined, slimmer sibling of the iconic Luminor. Available in references like PAM00927 and PAM01046, the Due retains the crown-protecting bridge and Italian military DNA in a thinner, more elegant package. Its growing popularity has attracted counterfeiters. Here's how to tell genuine from fake.
How to authenticate a Luminor Due
Slim Crown-Protecting Bridge
The Due retains Panerai's patented crown bridge but in a proportionally slimmer design to match the thinner case. The lever should lock down with a firm, precise click and sit perfectly flush against the case. The bridge pivots smoothly with no lateral play. Despite being thinner than the standard Luminor bridge, it should feel solid and substantial. Counterfeits often have a wobbly bridge that doesn't lock securely, excessive play when lifted, or proportions that don't match the Due's refined dimensions.
Thinner Case Profile
The Luminor Due is approximately 10.7mm thick, significantly thinner than the standard Luminor's 15-16mm. This slim profile is the Due's defining characteristic. The case sides should be beautifully polished with clean transitions. The thinner case achieves only 30 meters of water resistance (compared to 300m on the standard Luminor), so a Due claiming 300m water resistance is immediately suspect. Counterfeits sometimes use a standard Luminor case thickness, which defeats the entire purpose of the Due's design.
Sandwich Dial Construction
Many Luminor Due models use Panerai's signature sandwich dial: a two-layer construction where the top dial has cutout numerals with a luminous disc behind. This creates visible depth where you can see the lume material recessed below the dial surface. Run a fingernail gently across to feel the edges. Some Due models use a traditional single-layer dial with applied indices; verify which type is correct for your specific reference. Counterfeits often use printed dials that lack the sandwich dial's three-dimensional depth.
Caseback Engravings
The Due caseback features the model reference (e.g., PAM00927, PAM01046), serial number (two letters followed by numbers), "OFFICINE PANERAI" text, "FIRENZE," water resistance rating (3 BAR / 30m), and material designation. All engravings should be deeply cut with uniform depth and consistent font weight. The serial number is unique to each watch and can be verified with Panerai. Counterfeits often have shallow engravings with incorrect fonts, wrong water resistance ratings, or missing details.
"OP" Logo on Bridge
The crown bridge bears the "OP" (Officine Panerai) engraving. On genuine Due models, this engraving is deep, clean, and perfectly centered on the bridge surface. The letters have consistent depth and width with sharp edges. Under magnification, there should be no rough edges, burrs, or uneven depth. Even on the Due's proportionally slimmer bridge, the "OP" should be crisply defined. Counterfeits often have shallow, off-center, or poorly defined engravings.
Dial Printing and Finishing
The Due dial features "PANERAI" text below the 12 o'clock marker and "LUMINOR DUE" text above the 6 o'clock position. Under magnification, all printing should be razor-sharp with no bleeding or fuzzy edges. The Due often comes in refined dial colors including blue (PAM00927), gray, and anthracite, with a sunburst or matte finish that should be consistent across the entire surface. The small seconds subdial at 9 o'clock should have precise graduation marks. Counterfeits show blurred text, uneven dial color, and poorly finished subdials.
Luminor Due counterfeit warning signs
Too Thick for a Due
The most telling sign of a fake Due is incorrect case thickness. The genuine Luminor Due is approximately 10.7mm thick — dramatically thinner than the standard Luminor. If the watch feels chunky or measures over 12mm thick, it is likely a standard Luminor case being passed off as a Due, or a poorly made counterfeit that didn't replicate the slim profile.
Wrong Water Resistance Rating
The Luminor Due is rated to only 30 meters (3 BAR) water resistance due to its thin case construction. If the caseback shows 100m or 300m water resistance, the watch is either a misidentified standard Luminor or a counterfeit. This is a quick and definitive check that requires no tools.
Wobbly Crown Bridge
Even on the Due's slimmer crown bridge, the lever must lock down firmly with a precise click and zero lateral play. If the bridge wobbles, doesn't lock flush, or feels flimsy when operated, the watch is almost certainly counterfeit. The mechanism should feel mechanically precise despite the thinner proportions.
Flat Printed Dial on Sandwich Models
On Due references that should have a sandwich dial, a flat printed dial with no visible depth at the numeral cutouts is a clear counterfeit indicator. Look at the numerals from an angle: genuine sandwich dials show visible layering where the top dial is cut away, revealing the recessed lume disc beneath. Printed dials are completely flat with no three-dimensional character.

Frequently asked questions
What is the difference between a Panerai Luminor and Luminor Due?
The Luminor Due ("Due" meaning "two" in Italian) is a slimmer, more refined version of the classic Luminor. While both share the iconic crown-protecting bridge design, the Due is significantly thinner — approximately 10.7mm compared to the standard Luminor's 15-16mm. This is achieved through a slimmer movement and reduced water resistance (30 meters vs. 300 meters). The Due is available in 38mm and 42mm case sizes, making it more versatile for everyday wear and dressier occasions.
How can I authenticate a Panerai Luminor Due?
To authenticate a Panerai Luminor Due, start with the crown-protecting bridge — it should lock down with a firm, precise click and sit flush against the case. The Due's thinner profile is a key identifier; it should feel noticeably slimmer than a standard Luminor. Check for the sandwich dial construction on models that feature it, examine the "OP" engraving on the bridge for depth and centering, verify the caseback engravings for the correct 3 BAR water resistance rating, and inspect the dial printing under magnification.
How much is a Panerai Luminor Due worth?
Panerai Luminor Due models range in price depending on material and configuration. Stainless steel models like the PAM00927 (42mm, blue dial) and PAM01046 (38mm) typically retail between $7,000 and $10,000. Gold and titanium variants can reach $15,000 to $25,000. On the secondary market, pre-owned steel Due models typically sell between $5,000 and $8,000 in good condition. The Due has gained popularity for making Panerai's iconic design accessible to those who prefer thinner, more versatile watches.
