As far as background goes, in its first days Panerai had already used 8-day power reserve sequences powered by Angelus movements. This was to meet military requirements in a bid to produce the watches more reliable over a longer period of time and, reportedly, to not demand constant adjustment of the time and rewinding of their movement, saving the crown gaskets from early wear.Speaking of that, I entrusted it for you men out of fascination: it takes about one minute and 45 minutes to completely wind a stopped motion – and boy, is that a lot of twisting! Winding isn’t one of the enjoyable experiences the PAM561 can offer, either. Since the crown hardly extends over the plane of the concave top of the crown shield, you have to let go and grab hold of this crown innumerable times while the sharp edge of the shield itself and also the coined edge of the crown make things a bit less comfortable.The movement itself is in line with Panerai manufacture grade aesthetics: it’s rocky first, intriguing second, and lovely third. It’s one of the most rugged-looking calibers out there, with just one massive plate covering the gear train and the 2 barrels, and a single bridge that holds the balance wheel secure. Revealed is a massive – and I do mean huge – third wheel that is secured by a skeletonized bridge. Deep underneath it, near the barrel, is the centre wheel while nearer to the balance wheel, and again deep in the guts of the movement, is the fourth wheel along with the escapement.The balance wheel itself is obviously a free-sprung structure, meaning its accuracy is corrected through the old-school and more elegant means of variable moment of inertia screws in the periphery of the balance wheel. Panerai explains that the bridge supporting the balance is fixed by two screws beneath that are threaded rings which turn in both directions. The purpose of this is to correct the “end-shake” of this equilibrium staff pivots. This technical solution helps 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.
