The elegant, streamlined form, innovative indications, and ergonomic functions of Chapter One belie the incredible complexity of its unique movement.
A tour of the dial reveals central coaxial hours, minutes, and chronograph 60-second counter; tourbillon and day of the week roller at 6 o’clock; retrograde GMT at 9 o’clock; 60-minute chronograph counter and precision moon phase roller at 12 o’clock; and retrograde date at 3 o’clock.
The two rollers work simultaneously with the time, date, GMT, and chronograph and are large enough to be easily read and small enough to be ultra-light and homogeneous with the case.
A small window between day roller and tourbillon allows a unique view of the superbly finished gyrating tourbillon cage.
Mirror-polished angled surfaces bring the multi-level dial to life, and even the locking corrector pushers are from curves meeting at an imaginary point to follow the graceful flow of the case.
