Nicolas (amanico) presents a rare and highly sought-after trio of Panerai Pre-Vendôme Slytech references, offering a glimpse into a pivotal era for the brand. This post serves as a valuable historical document, showcasing the 5218-205A Submersible, 5218-207/A Daylight, and 5218-304 Mare Nostrum. His personal reflection on owning these pieces underscores their enduring appeal among collectors.

The Panerai 5218-304 Mare Nostrum is a notable early pre-Vendôme reference, distinguished by its smooth bezel and chronograph complication. This model represents a significant reinterpretation of a historical Panerai prototype from the 1940s, adapted for a civilian market. It stands apart from other pre-Vendôme Luminor and Submersible models by offering a different functional focus and aesthetic, appealing to collectors interested in the brand's broader design heritage beyond its more commonly known dive watch forms.
This reference features a steel case, measuring 42mm in diameter. The movement is a hand-wound ETA 2801-2 base, modified with a Dubois Dépraz chronograph module. The crystal is sapphire, with a thickness of 1.6mm. Water resistance is rated at 50 meters. The watch is fitted with a leather strap.
As one of the pre-Vendôme era releases, the 5218-304 Mare Nostrum holds particular appeal for collectors focusing on the period before Panerai's acquisition by the Vendôme Group. Its smooth bezel variant is specifically mentioned as a distinguishing characteristic among the Mare Nostrum series, making it a distinct piece within the early production run. It represents a different facet of Panerai's design exploration during its re-establishment phase.
When was the submersible line introduced as a separate line with the rotating diving bezel?
Panerai is not my thing, but I could make an exception for that 304.
I think it’s 5218-301?
but from the markings on the bezel?
It is too bad the brand has gone the way that it has…all the complaining about releasing similar watches, but, that is what I loved about the brand…guess I was in the minority! Love these! Thank you for sharing, my friend!
that I realize how much of a fiasco has the Mare Nostrum been, for the maison. They have "refreshed" most of the oldies (with mixed fortunes) and even in the era of complications and chronographs...the M.N. has remained in it's coffin, away from public viewers..
