The Sonata is an amazing multifunctional mechanical instrument and developed in-house and inspired by Dr. Ludwig Oechslin, constructed by Pierre Gygax and Lucas Humair.
The engineers and technicians of Ulysse Nardin spent nearly seven years on the development of this patented self-winding calibre. It combines the novel alarm setting with a countdown indicator and the dual time system with the instant time zone adjustor conceived by Dr. Oechslin and featured in many Ulysse Nardin watches.
This patented dual time function permits time zone adjustments forward and backward by simply pressing the pushers plus (+) or minus (-) to change the position of the hour hand. The original home time (reference time) stays displayed while the date, the alarm and countdown adjust automatically when a time zone adjustment is made.
