High-Frequency Chronograph Watchmaking
Specialist Care for Zenith & El Primero
Zenith is particularly associated with precision chronograph watchmaking, most famously the El Primero. These high-frequency mechanical movements require careful diagnosis, correct lubrication, regulation and testing.
We inspect the movement, automatic winding system, chronograph mechanism, setting functions, crown, crystal, seals, case and bracelet before preparing an estimate. Vintage pieces are approached with particular care so unnecessary cosmetic changes are avoided.
