Monobloc Actuator

Introduced in 2018, the Monobloc Actuator is the most technically ambitious collection made by Porsche Design since the opening of the Solothurn manufacture. The name literally describes its main feature: instead of traditional pushers, the chronograph is operated by a single rocker lever integrated into the case, which the brand presents as a watchmaking translation of the mechanical valve-actuation system used on Porsche racing engines, such as that of the 911 RSR.

The case, entirely in titanium and made as a single monolithic block — hence the name "monobloc" — integrates the actuation mechanism into one body instead of having separate pushers screwed to the case, following a construction logic closer to motor engineering than to traditional watchmaking. Some executions feature a black titanium carbide coating, in keeping with the dark aesthetic that has accompanied the brand since 1972.

At the heart of the collection is the WERK 01.200, a caliber developed in-house in Solothurn from a deeply reworked Valjoux/ETA 7750 base, with a flyback function. Initially launched as a limited edition, the line later expanded with variants featuring a 24-hour totalizer and a second time zone, while retaining the same single-lever construction principle.
