As expected from the prestigious firm of Haas Neveux, one of the foremost Swiss manufacturers, this watch is of very high grade throughout. The complexity of a jump hour is the regulation of power and the precision of keeping time correctly at the same time. Unlike a traditional time display which uses a constant force, the jump hour needs also a power peak for ‘jumping’ the hour disc.
