Vacheron Constantin Injects Even More Power into its Traditionnelle Twin Beat Perpetual Calendar
Vacheron Constantin has updated its Traditionnelle Twin Beat Perpetual Calendar, extending its standby power reserve to 70 days. The watch features a unique dual-heartbeat system designed to solve common mechanical issues in high-end horology.
Why it matters
This represents a technical advancement in luxury watchmaking, addressing the balance between complex complications and user convenience.
Perpetual calendars are incredibly sophisticated creatures with an intricate mechanical memory that can display the correct day, date, month and leap year until 2100 without intervention, provided they are constantly wound. Notoriously power-hungry and fragile complications, if you forget to wind the watch, you face the laborious task of resetting the day, date, month and leap year, usually with a fiddly tool. According to Christian Selmoni , the brand’s longstanding Style and Heritage Director, this was one of the main directives guiding the development of the Twin Beat.
