Obsession.
In 1889, Édouard Vallat left the Patek Philippe atelier with a single conviction: that a movement should be built to outlast its maker. In a narrow workshop on Rue du Rhône, Geneva, he began hand-turning components that would define a house for generations.
Today, the Vallat family's fifth generation oversees a manufacture of forty-two artisans, each trained for a minimum of seven years before touching a finished movement.

The Living Calibre
Time,
Time,
as it
happens.
Every Aurum Tempus movement is regulated to ±2 seconds per day — better than COSC chronometer standards. What you see to the right is not an animation. It is the current time in Geneva, rendered through the geometry of our Calibre AT-1889.
The sweeping seconds hand runs at 28,800 vibrations per hour — indistinguishable from continuous motion to the human eye.
