and classical beauty. Utilizing a selfwinding mechanical movement which has been carefully adjusted for precise timekeeping and reliable performance, the watchmakers at Ulysse Nardin have incorporated a unique mechanism by which the hour hand can be advanced ahead or set back in one hour jumps, with a simple push of the buttons on the side of the case band. During this operation, the minute and second hands continue normally, ensuring that the precise time is not affected as the user navigates through the hourly timezone changes. At the same time, a small window in the dial indicates the time of the wearer's home location, enabling a quick and easy reference while on the go. The date mechanism, protected by a patent, displays two numerical discs, which makes reading it an easy matter, and also allows for both backwards and forwards adjustments.
