Officine Panerai Luminor 1950 Tourbillon GMT Ceramica PAM 00396. If you are looking for the flagship Panerai released at SIHH 2012, it has to be Luminor 1950 Tourbillon GMT Ceramica PAM00396. This watch combines the dual time with the Tourbillon complication. Dual time is displayed in the usual Panera way. A second hour hand that rotates once every twelve hours is used, instead of the more common 24-hour hand. In order to determine whether it is day or night in the second time zone, a small dial at 3 oclock has a am/pm indicator.
The watch does not have an open dial which shows the Tourbillion movement on its face. Insteas a small seconds dial, at 9 oclock, ontains an a series of dot markers, which is connected to the tourbillon and moves at twice the speed of the seconds hand, completing one revolution in 30 seconds.
What is a tourbillon? The tourbillon was invented in 1795 by Abraham-Louis Breguet. Mechanical timepieces are affected by gravity. In order to counter the effects of gravity, Abraham-Louis Breguet built a watch that counteracted gravity by rotating the balance wheel of a watch or clock through 360 degrees. This is called a tourbillon.
This is accomplished by mounting the escapement in a rotating frame, called a "carriage" which turns at regular intervals, usually once a minute. This rotation reduces the positional errors of the movement.
At that time almost Abraham-Louis Breguet invented the tourbillon almost all watches were pocket watches which stayed in one position most of the time. The only time a pocket watch changes position is when it's taken out by the owner to check the time.
The effect of gravity on a watch or clock kept in one position all the time, like a pocket watch, is particularly noticeable on the escapement, especially the balance which rocks back and forth. This can lead to inaccuracies. Breuget's solution was the tourbillon.
Today, most tourbillons are found in wristwatches. People tend to move their arm as they go about their day, which provides the changes in position required to offset the effects of gravity on the watch movement. This negates the need for one a tourbillon. Today tourbillon watches are valued as a display of watchmaking prowess, in the same way complication watches are desirable.
Ceramica. The PAM 396 has a 48 mm diameter Luminor 1950 case with a synthetic ceramic based on zirconium powder which coating. This process creates a uniform and even matt black appearance, as well as ensuring excellent performance in terms of hardness, resistance to scratches, corrosive agents and high temperatures. The case is made from stainless steel and titanium.
Movement. Inside, is the built by Panerai P.2005 which produced 28,800 vibrations per hour and has a long 6-day power reserve. The movement has a sapphire crystal on the caseback allowing you to view the movement and power reserve indicator.
