Caliber Octa is an invention of F.P. Journe

In 2001, a watchmaker Francois - Paul Journe released a line of Octa. It is a collection of mechanical wristwatches with large power reserve (120 hours) and automatic winding. All models of caliber Octa regardless of the complexity of functions are the same size. This was the opening of Journe, which immediately gained success. Octa collection will fit perfectly lovers and fans of innovative, unique and mechanical watches, which are very easy to use. Francois - Paul is a true master of the Journe of watchmaking and is constantly improving its creation. The collection is able to deliver a variety of joy to collectors, due to various complex functions, such as the moon phase indicator, the annual calendar. Journe told that coming up with this kind of caliber, which would remain complicated and did not increase in size (30 mm in diameter and 5.7 mm in thickness), it was very difficult, and it was engaged in the development of 5 years. But it was important to create an exquisite variety of innovative watches on the base caliber, which would ensure the stability of the chronometric and accuracy, based on a variable inertia and automatic winding. For example, Paul developed new caliber with automatic plant. For the first time the movement of Octa was used in the model with power reserve Octa Reserve de Marche (2001), and then graduated Octa Calendrier (2002) and Octa Lune with indicator of lunar phases (2003). Soon came a new Octa caliber 1300 3. It permits to use the plant for the slightest movement of the chronograph hands. Talented Journe has created a new rotor, which is put only in one direction, unlike the previous caliber. The system of ceramic ball bearings, blocks the movement in the opposite direction and allows the rotor to move only in one direction. When the chronograph in the same position, the rotor is again in its original position. It turns out that the most minor action arm is used for factory watches. Although the caliber of Octa 1300-3 - the latest development watch house F.P. Journe, he retained some old features: a five-day power reserve (120 hours) and the balance with variable inertia, which ensures maximum stability. In the collection of watches, which have a caliber Octa, are: Octa Calendrier, Octa Chronographe, Octa Lune, Octa Reserve De Marche, Octa Divine 36, Octa Divine 38.
