Background
Cologny is one of the wealthiest municipalities in Switzerland. Chemin de Ruth is among the most expensive streets in the country. High-end real estate is seen as a safe investment, while Swiss watchmaking is going through a crisis.
The key points
Thierry Stern, head of Patek Philippe, has bought a villa on Chemin de Ruth for CHF 38 million. Business magazine Bilan revealed the transaction, which Blick reported on 6 November 2026.
The property comprises two buildings, with more than 500 m² of living space, on a 5,628 m² plot. The seller, Thierry Halff, sits on the board of Maus Frères, owner of Manor and the Lacoste brand.
Thierry Stern has headed the Geneva manufacture since 2009. According to Blick, Patek Philippe is weathering the watch industry crisis without faltering, thanks to a strategy of scarcity.
