GRAND TONNEAU JUMP HOUR - MNL.02

We have always been fascinated by the Jump Hour complication. The Jump Hour mechanism is a rare and fascinating complication that first gained prominence in the early 20th century, celebrated for its clarity and mechanical ingenuity.

Unlike traditional watches, where the hour hand moves continuously, this movement allows the hour to “jump” precisely at the turn of the hour—a mesmerizing mechanical feat.

For the Grand Tonneau Jump Hour collection, we have in-house modified the automatic Jump Hour movement (ST1721). This movement has been expertly engineered to showcase time through two rotating discs, seamlessly aligning with the collection’s distinctive design language.

Before assembly, each movement undergoes a rigorous two-week in-house testing process, ensuring flawless performance and reliability.
