With the Classic Sonata, mechanical complications are always designed with the wearer in mind, the goal being a perfect fusion of form and function. This edition of the Classic Sonata has a streamlined design. After all, simplicity is the ultimate form of sophistication. But don't be deceived, this timepiece is also incredibly functional.

Mechanical complications pared down to their most essential form make this timepiece an ideal travel companion. An alarm function which wakes the user with a pleasant cathedral chime is positioned between 12 o'clock and 2 o'clock. In the center of the counter, the 'countdown' display of the last 12 hours, allows to select a wake-up in the morning or in the afternoon.

Another exclusive Ulysse Nardin innovation, the Dual Time function, means both home time and current time can be viewed simultaneously. The watch is  driven by the UN-67 manufacture movement. It has a silicium escapement and a power reserve of 42 hours. As always, time zone adjustment can be made both forwards and backwards, just by using the pushers to change the position of the hour hand.

The Classic Sonata is ever elegant, in two editions that highlight the essential beauty of the functions: eternal black and rose gold, or stainless steel with blue markers, each with a black alligator strap. Both models have a 44-mm diameter case, water resistant to 30 meters, with a sapphire crystal case back.

The price is $24,800 for the  Classic Sonata in steel and $42,800 for the rose gold.
