EXPOSED MOVEMENT

The evolution of our structural origins. The A003 reinterprets the octagonal case through millimetric refinements to its proportions. The Landeron DP20 movement remains visible, reinforcing the aesthetic identity that has defined ACTO since its earliest days.

SKELETON DIAL

The skeletonized design eliminates visual barriers, offering a clear view of the internal mechanism beneath the sapphire crystal.

CUSTOM ROTOR

The sapphire crystal case back offers a new perspective on the movement. Its open-work design was created to balance ACTO's aesthetic identity while maximizing efficiency and providing a more complete view of the moving gears.

ULTRARUBBER™ STRAP

Made from FKM Rubber, the strap offers outstanding resistance to temperature variations, sweat, and tensile stress. Its integrated 25 mm-wide design ensures mechanical stability and a secure fit on the wrist.

Caseback

The sapphire crystal case back provides a new perspective of the movement.

The new custom ACTO rotor, visible through the case back, is responsible for storing energy for the automatic movement.
