F.P. Journe Classique Chronomètre Souverain Platinum 40 MM - Black Leather Strap - Silver Dial - Chronomètre Souverain

40 mm, platinum case. The Chronomètre Souverain is a precision chronometer that was inspired by the marine chronometers of the early 19th century. Constructed in the purest chronometric tradition, it has an extra-flat movement that is 4 mm thick; its base plate and bridges are in 18K rose gold. The two barrels of the homogeneous movement deliver a highly linear force to the escapement for over fifty-six hours. The escapement beats at a frequency of 21,600 vibrations per hour.
