From our pre-owned inventory: Panerai Luminor Base Logo PAM01623, a 44mm steel watch with a blue dial and the signature crown-protecting bridge.
Panerai’s lineup comes down to five families. The Luminor has the crown-protecting bridge. The Luminor Marina is a Luminor with small seconds, the Luminor Due is the thinner, dressier Luminor, the Radiomir is the older cushion-case design without the bridge, and the Submersible is the dive watch with a rotating bezel. Once you know those differences, the PAM numbers start to make sense.
Panerai is one of the brands we stock most often, and the naming confuses many buyers. Here is the plain-English version.
A quick history
Panerai’s story is rooted in the Italian Navy. The Radiomir name appears in an addendum to a French patent filed in 1916 for a radium-based luminous material, and Giuseppe Panerai commissioned watch prototypes for naval tests in the mid-1930s, according to Panerai’s history. Panerai registered the Luminor trademark in 1949, patented the crown-protecting bridge in 1956, and moved toward civilian production in 1993. Our earlier article on the Panerai Luminor’s military origins tells that story in more detail.
Luminor: the bridge
The Luminor’s defining feature is the lever-locking bridge that protects the crown and helps keep it sealed. If you picture a Panerai, you are probably picturing a Luminor.
- Luminor Base: hours and minutes only, the most minimalist dial. Our Luminor Base Logo PAM01623 is a good example.
- Luminor GMT and power-reserve models: add a second time zone or power-reserve indicator. See our Luminor 1950 3 Days GMT PAM00321 and PAM00320.
Luminor Marina: small seconds
“Marina” indicates a Luminor with a small-seconds subdial, usually at 9 o’clock. Panerai traces the small-seconds display to commandos’ need to synchronize operations and watches, and lists the current Luminor Marina PAM01312 with automatic calibre P.9010 and hours, minutes, small seconds, and date, per its Luminor collection page.
- Best for: buyers who want the classic Luminor look with a running seconds indicator.
Luminor Due: thinner and dressier
Introduced in 2016, the Luminor Due slims the Luminor down for better wear under a cuff. Launch coverage from aBlogtoWatch described the first hand-wound 42mm models as 10.5mm thick with the P.1000 calibre. Later versions include automatic movements and smaller sizes.
- Best for: smaller wrists, office wear, or anyone who finds a standard Luminor too thick.
Radiomir: the original cushion case
The Radiomir is Panerai’s older design: a cushion-shaped case without the crown-protecting bridge, often with a more vintage feel. Many Radiomir models feel lighter and dressier than a Luminor of the same diameter.
- Best for: collectors who love history and want the most elegant side of Panerai.
- Buying tip: Radiomir variants, such as the 1940, California dial, and Quaranta, differ in case shape, size, and movement, so compare carefully.
Submersible: the dive watch
The Submersible adds a unidirectional rotating dive bezel to the Luminor case. Current steel models such as the PAM01289 are 44mm, use the automatic P.900 calibre with a three-day power reserve, and are rated to 300 meters, according to Panerai. The QuarantaQuattro versions bring a slimmer profile within the Submersible range.
- Best for: divers, water sports, and buyers who want maximum Panerai presence.
Decoding PAM numbers and case sizes
Panerai identifies every reference with a PAM number. The number does not describe the model by itself, so always check the full name, case size, and movement. The same family can appear in 38mm, 40mm, 42mm, 44mm, and 47mm versions, and the 44mm Luminor wears larger than many 44mm round watches because of its cushion case and bridge. Our watch size guide explains why lug-to-lug length matters.
Buying pre-owned Panerai
- Value is strong for buyers. Pre-owned Panerai often costs well below retail.
- Enjoy straps. Panerai is famous for strap changes, so a watch with extra straps adds real enjoyment.
- Check the lume and dial. Panerai dials are simple, so any damage or inconsistency is easy to see and important to price.
- Hand-wound or automatic? Many Panerais are hand-wound. Make sure you are happy with daily winding.
Panerai questions
What is the difference between Luminor and Luminor Marina?
A Luminor Marina has a small-seconds subdial. A Luminor Base shows only hours and minutes.
Is a 44mm Panerai too big?
It depends on your wrist and the lug-to-lug length. Many wearers prefer 42mm or a Luminor Due for a smaller fit.
Is the Radiomir water-resistant?
Ratings vary by reference. Check the specific model before swimming.
