As far as history goes, in its earliest days Panerai had already used 8-day power book watches powered by Angelus moves. This was to fulfill military requirements in an effort to make the watches more reliable within a longer period of time and, allegedly, to not demand constant adjustment of their time and rewinding of their movement, rescuing the crown gaskets from early wear.Speaking of which, I timed it to get you men out of curiosity: it requires roughly one minute and 45 seconds to completely wind a stopped movement – and boy, is that a lot of winding! Winding is not one of the enjoyable experiences the PAM561 could offer, either. Since the crown barely extends across the airplane of the concave top of the crown guard, you have to go and grab hold of this crown countless times while the sharp edge of the shield itself along with also the coined edge of the crown make things somewhat less comfortable.The motion itself is in accord with Panerai manufacture caliber aesthetics: it’s rocky first, interesting second, and lovely third. It’s among the most rugged-looking calibers out there, with only one massive plate covering the gear train and the 2 barrels, and a single bridge which retains the balance wheel secure. Revealed is a massive – and I really do mean huge – third wheel that is secured by a skeletonized bridge. Deep underneath it, near the barrel, is the center wheel while closer to the balance wheel, and again deep in the guts of this movement, is the wheel along with the escapement.The balance wheel itself is obviously a free-sprung structure, meaning its accuracy is corrected via the more old-school and more elegant means of varying moment of inertia screws in the periphery of the balance wheel. Panerai clarifies the bridge supporting the equilibrium is fixed by two screws beneath which are threaded rings that turn in both directions. The objective of this is to correct the “end-shake” of this equilibrium staff pivots. This technical solution assists the escapement to keep on running more easily in case of shocks.
For the new Luminor Submersible 1950 Carbotech PAM616, Panerai has turned to a carbon fibre reinforced polymer known as Carbotech for the case, bezel and crown lever bridge, the first time Panerai has used a carbon fibre composite.
Long popular with brands like Hublot and Richard Mille, it is now Panerai‘s turn to use carbon fibre composite for a watch case. The new Luminor Submersible 1950 Carbotech 3 Days Automatic (PAM00616) is named after the carbon fibre reinforced polymer used for make the case, bezel and crown lock bridge. Carbon fibre composites like Carbotech have a characteristic wave-like pattern due to the layering process used to make the material. Sheets of carbon fibre are laid on top of each other, with a polymer resin in between to hold it together. It is then put in an autoclave, a sort of high pressure oven, resulting in a light and strong composite. The distinctive striped appearance is due to the layers of carbon fibre inside.
Rated to 300 m, like most of the other Panerai Submersible watches, the case is 47 mm in diameter, with blue accents on the dial as well as parchment coloured Super-Luminova.
While the case is carbon composite, the screw-down back is titanium due to the fact that carbon fibre composite not reacting well to torsional (or twisting) forces. The PAM616 is equipped with the P.9000 automatic movement and a rubber strap. The Submersible Carbotech is part of the regular collection, with pricing yet to be announced.
