Panerai Mare Nostrum, Ref. PAM00008

When you buy something, whether it's clothing, cars, or jewelry, you probably like it because of the way it makes you feel. It's a ridiculous need we have for identity. We send out signals socially and broadcast to those around us. Whether I drive a Porsche or a Toyota, the brand says a little bit about me. Buying watches is no different, and brands like Panerai tap into this need. Why pick a Panerai? Well, first, it will be rare to find someone else with one. Rolexes abound and you may even see a few every week. Panerai, not so much. The Mare Nostrum, even less so.

So, why would anyone select one if objects like watches project something about us? Well, being obscure, rare, bold, and somewhat utilitarian could be the brand you're going for, whether you know it or not. And among those few that care, this one is pre-Vendome, before Panerai was corrupted by the world of large corporate interests. I'm mostly joking, but these watches are considered to be from the golden age of Panerai, before 1998.

Personally, I love this watch and also have the PAM00716. I would also love to have the PAM00007, the one with a white dial, but I had to draw the line somewhere, right? Sounds like I'm the dude broadcasting that I am like a Mare Nostrum, a utilitarian throwback, maybe lost in time.

Brand and history

Panerai was founded in Florence in 1860 as a watchmaking school and shop. The company became a supplier to the Italian Navy, producing luminous instruments, depth gauges, compasses, and timing devices for military operations. That naval relationship lasted most of the 20th century.

The Mare Nostrum's origin story is where things get interesting. According to Panerai, they developed this chronograph in 1943 for Italian Navy deck officers. The name translates from Latin as "Our Sea," the Roman term for the Mediterranean that Mussolini's regime had revived. Only prototypes were supposedly made before the war halted production.

But independent research, particularly by Jose Pereztroika of Perezcope.com, raises serious doubts about that 1943 date. When you compare the Mare Nostrum's case design to other Panerai instruments across decades, early compasses from 1940 and 1944 look nothing like it. Place the Mare Nostrum next to depth gauges from 1955 onward and the match is immediate: identical lug shapes, identical inter-lug geometry. A Panerai compass marked "GPF 4/55" has the same design language. The case design belongs to the 1950s, not the 1940s.

Almost all records were destroyed when Florence flooded in November 1966. A single photographic plate survived, showing the watch in three-quarter view. That plate became the only reference for every reproduction that followed.

In 2005, a Mare Nostrum prototype surfaced at Christie's Geneva. Angelo Bonati, then CEO of Richemont's Panerai division, purchased it for CHF 132,000. It now sits in the Panerai Museum. Here is where it gets strange: the prototype's caseback is nearly identical to the caseback on the 1993 replica. The designers of that 1993 version were working only from the front-and-side photographic plate. They had no image of the original's rear. Mario Paci, Panerai's quality assurance manager until 1997, confirmed to Pereztroika that the 1993 caseback was improvised. The odds of accidentally matching a convex shape and slotted tightening method that closely seem remote.

The modern Mare Nostrum story begins with Dino Zei, a naval engineer who took charge of Panerai after the last family member, Giuseppe Panerai, fell ill in the 1970s. The Italian Navy wanted to keep its instrument supplier alive, but military contracts eventually dried up. Zei sensed opportunity in the early 1990s when vintage Rolex collecting surged. Many Panerai military watches had been built by Rolex with Rolex movements, which put Panerai on collectors' radar.

On September 10, 1993, Zei launched Panerai's first civilian watches: the Luminor (ref. 5218-201/A) and the Mare Nostrum (ref. 5218-301/A). The 52mm prototype was shrunk to 42mm. A tachymeter bezel was added. Approximately 990 cases were made for the 5218-301/A. Of these, about 492 became true pre-Vendome pieces with blue dials. The rest were transferred to the Vendome Luxury Group when it acquired Panerai in March 1997.

Vendome reworked 398 of those cases with new dials, bezels, casebacks, and straps. The minute track moved to the outside of the hour markers and the bezel got a polished inner ring. Three references came out of that rework, distinguished only by dial color: the PAM00006 (blue, 120 pieces), PAM00007 (white, 90 pieces), and PAM00008 (black, 172 pieces). Production stopped when the parts ran out.

So the PAM00008 is a strange object. It was assembled from cases originally manufactured for the pre-Vendome blue-dial version, then reworked under new corporate ownership, based on a prototype whose age is disputed. Not many watches have that kind of confused lineage.

Case and dimensions

The case is stainless steel, 42mm in diameter and 12mm thick, with a 22mm lug width. The diameter feels right. It's modest by Panerai standards, where 44mm is the baseline for most Luminor and Radiomir models. The watch looks heavier than it actually is. Weight and thickness are not noticeable on the wrist.

The tachymeter bezel is angled, which is one of the visible differences from the PAM00716. That watch has a flat bezel made with more steel. The angled bezel on the PAM00008 gives the case a slightly slimmer profile even though the two watches share the same 42mm diameter.

The caseback is closed and screwdown with slotted tightening. The crystal is sapphire at 1.6mm. Water resistance is 50 meters, enough for handwashing and rain but not for any real water activity.

The dial

I appreciate the spartan, monochromatic design. There is as much on this dial as necessary and no more than what is necessary. The black dial, black subdials, and white printing create a layout that is simple without being minimal in any designed sense. This is not Bauhaus simplicity or a Max Bill exercise in reduction. It is military tool watch simplicity. Nothing fancy.

Still, the PAM00008 has a bit more going on than the more stripped-down PAM00716. The tachymeter scale on the bezel adds visual information. The dial uses a mix of Arabic numerals and markers with stick hands. Small seconds sits at 9 o'clock, the 30-minute chronograph counter at 3 o'clock.

The lume is tritium, marked T-SWISS-T on the dial. This dates the Vendome-era pieces. Later Panerai models switched to Super-LumiNova. The tritium will continue to develop patina over time, which is either a selling point or a concern depending on your view of aging materials.

The movement

The PAM00008 runs the OP XXXIII, Panerai's designation for a modular chronograph setup. The base is an ETA 2801-2 hand-wound caliber with a Dubois-Depraz 3127 chronograph module bolted on top. Manual wind only.

A common misconception identifies this movement as a Valjoux 7733. That movement, a cam-switching manual-wind chronograph produced from 1969 to 1978, was never used by Panerai. Another mix-up involves the OP XXV, which is a completely different caliber. The OP XXV is a hand-finished Minerva 13-22 column-wheel movement with 22 jewels and a swan's neck regulator. It was reserved for the 52mm Mare Nostrum re-editions: the PAM00300 (2010, 99 pieces) and PAM00603 (2015, 300 pieces in titanium).

The ETA/Dubois-Depraz combination is practical, not fancy. It works and it keeps working. What surprised me is how fresh the movement still feels despite this watch dating to 1997. The chronograph pushers have satisfying clicks and winding is smooth and easy. Hard to believe this watch is nearly 30 years old based on how the movement operates. The closed caseback means you will never see it, which is fine. This is not a movement you buy to admire through a display back.

On the wrist

The 42mm case does feel a bit undersized for a Panerai. On my 7.5-inch wrist it wears comfortably but without the wrist presence that Luminor and Radiomir owners expect. That is part of what I like about it. When every Panerai you encounter is either a Luminor or a Radiomir, the Mare Nostrum is a diamond in the rough that even people into Panerai have often never heard of.

The black NATO strap suits the watch. It matches the monochromatic dial and fits the utilitarian character. The original strap was black alligator leather, and I'm sure that looked fine, but the NATO feels more in keeping with the military roots this watch claims.

Final thoughts

The PAM00008 is a watch I love owning. It has a strange and contested history, and only 172 were made. On the secondary market it trades between $12,500 and $16,000, roughly ten times its original retail price of about EUR 1,500. WatchCharts data shows the PAM008 gained 1.1% over the past five years while the broader Panerai market dropped 22.2% over the same period. Scarcity has given it real price support.

But would I recommend it? Unless you are a dedicated Panerai collector, probably not. The PAM00716 from 2017 covers the same Mare Nostrum design in a newer, cheaper, and more easily serviced package. It has 1,000 pieces in production and retailed for EUR 9,900. If you want the Mare Nostrum experience, the 716 is the most practical choice.

The PAM00008 is for someone who cares about the specific history and wants a pre-Vendome-era case with a tritium dial. Someone who would rather own one of 172 than one of 1,000. I'm that geek.
