The Ultra-Complicated Calibre 1150

At the heart of this creation beats Calibre 1150, a new hand-wound movement counting 1,099 components, which brings together 40 functions (among which 22 are complications)*, including a minute repeater, perpetual calendar, split-seconds chronograph and flying tourbillon.

*These numbers may vary depending on sources and interpretation. Under the Federation of the Swiss Watch Industry (FH) standard, the total may reach 60.
