If you are a Panerai fan, you may know something about this watch. The reason is simple, that’s because it is the third iteration of the Mare Nostrum, dating from the early days of the fake Panerai. The Mare Nostrum was the first chronograph ever manufactured by Panerai, first launched in 1943 for the Italian Navy. The design was later recovered in 1993 as the first re-edition, which was in production until 1997. The watch you see here is almost completely similar to that 1993 re-edition, though with several small updates.
This watch begins with a 42mm AISI 316L stainless steel case, just like the 1993 edition, with round chronograph pushers, and a tachymeter bezel calibrated to 60 Km/h. The very first Mare Nostrum measured in at a huge 52mm, so there is a rather big difference here, and it makes the watch which is actually wearable you know. The dial, which is also rather attractive and amazing, has two different colored accents: bright white for the signature and the two registers, and beige SuperLuminova (with a slight faux-patina vibe) for the indexes, Arabic numerals, and hands.
The water-resistant, screw-down case back with the OP signature inscribed. The fake Panerai decided to use the same movement as the pre-Vendome edition, the caliber OP XXXIII, which is based on an ETA 2801-2 with a Dubois-Depraz chronograph module. It is COSC-certified and has a power reserve of 42 hours.  Panerai
It’s rather exciting and great that the Panerai replica has stuck to the archives for this watch. It’s an attractive piece that will likely be a hit with new and old Panerai collectors alike. The newest is being manufactured in a series of 1,000 pieces and comes in a wooden box which is shaped like the Luigi Durand De La Penne, an Italian Navy destroyer ship from the era of the original Mare Nostrum.
