The two new submersible models from Officine Panerai, with the Luminor 1950 case in brushed titanium, have an automatic chronograph calibre with flyback function and they are available with a rotating bezel of titanium or black ceramic.

Many fundamental innovations which have marked the history of the mechanical watch were developed in the military field in the first half of the last century. In those years the highest possible quality was required from instruments created for use by specialist forces, which often operated in conditions of extreme danger, and their requirements gave rise to many of the functions which are found in luxury sports watches today. The new Luminor Submersible 1950 3 Days Chrono Flyback Automatic Titanio - 47mm from Officine Panerai reunites features which have in common the military context of their origins, and they appear as two contemporary watches with a strongly sporting character, with great personality and the purest Panerai identity.

Like all Panerai watches, the main world of reference is of course that of the sea. Professional underwater models that are water-resistant to a pressure of 30 bar (a depth of about 300 metres), the new Luminor Submersible 1950 watches have a large Luminor 1950 case, with a diameter of 47 mm. The iconic design of the case, immediately recognisable by the device protecting the winding crown, is integrated with an element whose historic origins go back to the model created by Officine Panerai in 1956 for the Egyptian Navy: the unidirectional rotating bezel for calculating the time of immersion.

Two versions of this are available: one with a bezel made entirely of brushed titanium (PAM00614) and the other with a special bezel of titanium to which a matt black ceramic disk has been applied, with linear markers and dots in titanium (PAM00615). Both models are supplied with a black rubber strap, soft and durable, ideal for an underwater watch and personalised with the OP logo in Panerai blue.

The other function of the new Luminor Submersible 1950 originating from requirements which arose in the military field in the 1930s is that of the flyback chronograph. Also known as the “retour en vol”, this function enables the chronograph hand that is already moving to be zeroed and instantly restarted by a single pressure, without it being necessary first to stop the hand and then to return it to zero. In the Luminor Submersible 1950 the push button which controls the stopping and starting of the chronograph is at ten o’clock, while the push button at eight o’clock operates the flyback function and zeros the chronograph hand after it has been stopped.

To ensure the simplest and clearest possible reading, the chronograph minutes and seconds hands are both positioned centrally on the central dial and distinguished from each other by being different colours: the seconds hand is blue while the minute hand is rhodium plated, advancing instantaneously with a jump every sixty seconds.

The colours chosen for the hands enhance the minimalist design of the black dial, with its dot-shaped hour markers and simple figures, and the small continuous seconds counter at nine o’clock. The two models have different elements at three o’clock: the model with the titanium bezel has the date window in this position while the model with ceramic bezel has the chronograph hour counter there.

The movement of the Luminor Submersible 1950 is the P.9100 calibre, the first automatic chronograph calibre developed and made in the Panerai manufacture in Neuchâtel. Many details bear witness to its sophisticated construction: the vertical clutch, the column wheel, the two spring barrels connected in series which guarantee a power reserve of three days, the oscillating weight which winds the spring barrels as it moves in both directions, and the variable inertia balance which oscillates at 28,800 vibrations per hour. To ensure the greatest accuracy when adjusting the watch, the mechanism has the device for stopping the balance wheel and the system which enables the hour hand to be moved backwards or forwards in jumps of precisely one hour, without interrupting the movement of the minute hand. The movement consists of 302 components and it is 133⁄4 lignes in diameter and 8.15 mm thick.

Both versions of the Luminor Submersible 1950 3 Days Chrono Flyback Automatic Titanio - 47mm are supplied with a spare strap, a screwdriver and the special tool for changing the strap.
