The Chronomètre Souverain is inspired by early 19th century marine chronometry, fitted with an ultra slim manually wound 18K pink gold movement of only 3.7 mm that beats to a frequency of 21,600 alt/hour. The two barrels, supplying a power reserve of over 50 hours, operate in parallel to provide a constant force for unequalled precision.
It is the first model in the Souverain collection to feature the brands' favourite blued hands. For the first time, the small subsidiary seconds dial is positioned to the left to 7 o'clock, while the 55-hour power reserve is placed to the right to 3 o'clock.
