Eterna Presents Calibre 39
The watch brand Eterna has released a new caliber 39. It is developed as a result of a project initiated in 2007. Feature of the mechanism is that it is a modular caliber, allowing it to produce 88 different versions - from a timepiece with two hands to split-chronograph with column wheel.
The mechanism is equipped with a 68-hour power reserve, a Spherodrive system. It is the development of Eterna, patented in 2006. It represents a new kind of a winding barrel that rotates on ball bearings to minimize friction and wear, and reduces the number of lubrication points in the caliber and significantly increase the reserve.
As stated by the company Eterna, 70% of the Calibre 39 will be released by the manufacture, which is located in Grenchen, Switzerland.
