In the world of haute horlogerie, striking watches such as minute repeaters and sonneries stand out as masterpieces of both engineering and artistry. At the heart of these intricate timepieces lies a crucial component: the governor. This silent conductor ensures that each chime is perfectly timed, creating a harmonious auditory experience. Over the years, the technology behind governors has evolved significantly, bringing about innovations that enhance the functionality and acoustic quality of these watches.
The Role and Evolution of Governors
Governors are essential in regulating the speed at which the hammers strike the gongs in a striking watch. This regulation maintains the clarity and rhythm of the chimes, ensuring that they are neither too fast nor too slow. There are two primary types of governors:
- Anchor Governors: These operate similarly to a lever escapement, using an escape wheel and an anchor to control the tempo. They produce a distinct buzzing sound, which some connoisseurs appreciate for its historical charm (Revolution Watch) (Revolution Watch).
- Centrifugal Governors: These use rotating arms to create friction and control speed. They are quieter and more efficient but tend to be bulkier compared to anchor governors (Revolution Watch) (Revolution Watch).
Innovations in Governor Technology
Recent advancements have introduced new materials and designs to improve the performance and sound quality of striking watches:
- Silent Strike Governors: Vacheron Constantin’s silent strike governor combines centrifugal and centripetal forces, reducing noise and offering a compact solution. This technology is featured in their Patrimony Traditionnelle calibre 2755, enhancing sound transmission and case integration (Revolution Watch).
- Fan Governors: Seiko’s Credor Spring Drive Minute Repeater uses a fan governor that employs air resistance to regulate the chiming speed, resulting in a virtually silent operation. This innovation allows for a purer, more meditative chime (Revolution Watch) (Hodinkee).
- Sapphire Gongs: Chopard’s Full Strike model integrates sapphire gongs with the watch glass, enhancing sound clarity and resonance. This design also eliminates silences between chimes, providing a continuous and harmonious auditory experience (Monochrome Watches).
Expert Opinions and Market Impact

Collectibility and Market Value
Striking watches with advanced governor mechanisms are highly prized among collectors for their technical sophistication and acoustic beauty. Innovations in governor technology not only improve functionality but also enhance the overall value and desirability of these timepieces. Brands like Patek Philippe, Audemars Piguet, and Chopard lead the market with their groundbreaking designs and meticulous craftsmanship (Hodinkee) (The Hour Glass Official).
Notable Examples
Seiko Credor Spring Drive Minute Repeater Seiko’s Credor Spring Drive Minute Repeater represents a significant leap in the use of silent governor technology. Unlike traditional mechanical governors, which can be noisy, Seiko employs a fan governor that utilizes air resistance to control the speed of the chiming sequence. This innovation results in a virtually silent operation, providing a pure and uninterrupted sound experience (Revolution Watch) (Hodinkee).
Chopard Full Strike Chopard’s Full Strike model uses sapphire gongs integrated with the watch glass, creating a unified piece of sapphire. This construction method enhances the clarity and resonance of the chime. The watch also features a novel architecture that eliminates the silences typically heard between chimes, ensuring a continuous and harmonious sound. Additionally, the movement employs a silent governor to minimize background noise (Monochrome Watches).
Patek Philippe Fortissimo “ff” Amplifier Patek Philippe’s Advanced Research 5750 Minute Repeater introduces the Fortissimo “ff” amplifier, which uses a thin synthetic sapphire wafer to amplify the sound mechanically. This system not only enhances the volume and richness of the chime but also maintains a compact design, allowing the watch to retain its traditional aesthetics while significantly improving its acoustic performance (Monochrome Watches) (Escapement Mag).
Vacheron Constantin’s Silent Strike Governor Vacheron Constantin has developed a silent strike governor that combines centrifugal and centripetal forces to regulate the speed of the chimes. This innovative mechanism offers a quieter and more compact solution compared to traditional centrifugal regulators. The Patrimony Traditionnelle calibre 2755 exemplifies this advancement, showcasing improved sound transmission and a more efficient governor system (Revolution Watch).
In conclusion, the evolution of governors in striking watches highlights the blend of tradition and innovation in horology. These advancements ensure that the enchanting sound of minute repeaters and sonneries continues to captivate watch enthusiasts and collectors around the world.
