Pre-V=Pre-Vendome (Acquisition)
From
http://www.paneristi.com/reference/prevendome.htmlWatches made between the "rebirth" of Panerai in 1993 to the acquisition of the company by the Vendôme group in 1996/97 are usually called "pre-Vendôme" models. The basic pre-Vendôme range consisted of some 44mm hand-wind watches with the classic 44mm Luminor case, and some 42mm Mare Nostrum chronographs. The line also included limited edition Slytech watches, endorsed or commissioned (depending on who you believe) by the film star Sylvester Stallone. The Slytechs are distinguished by the signature of Mr Stallone engraved on the caseback, and some writing on the dial.
All the pre-Vendôme models came on straps with the large "bottle opener" or "fancy" buckle, although the Mare Nostrum buckles were smaller than the full-sized ones.
Most watches came in an oak box, with additional paperwork and straps, however the Slytechs came in a very large box with all manner of gadgets such as the miniature submarine model.
