This article discusses a rare prototype watch designed by André Beyner and Maurice Grimm, the creators of the ultra-thin Delirium quartz watch. This automatic prototype, part of the 'Delirium Vulgare' project, aimed to create a more accessible automatic version of their groundbreaking thin watch. Its significance lies in its potential influence on both the high-end luxury market, by foreshadowing the Audemars Piguet 25643 (the first serially produced automatic tourbillon), and the lower-end market, through its integrated movement architecture, a concept later echoed in brands like Swatch and Casio G-Shock.

- Estimated between €40,000-€80,000
- Auctioned on the 10th
The prototype is an automatic version of the Delirium, with the project named 'Delirium Vulgare'.
The watch integrates the movement into the caseback, a design principle later seen in Swatch and Casio G-Shock.
The movement's architecture is considered a precursor to the Audemars Piguet 25643, the first serially produced automatic self-winding tourbillon.
The watch does not look pristine but is in phenomenally good shape, though the weight lacks etching seen on a Phillips example.
The shield logo beneath 12 o'clock, representing Beyner's and Grimm's former employer, is broken.
The textured bracelet is described as incredible.
