TAG Heuer has devoted all of its avant-garde, mechanical watch-making expertise to the achievement of precision. The Calibre S has an exclusive electro-mechanical movement, developed and patented by TAG Heuer. A real innovation in watch-making, the Calibre S represents a complete break from traditional codes of ordinary chronographs, which, since 1822, have used three counters that are difficult to read.
This revolutionary movement offers an innovative and intuitive interface for displaying the times measured: the central hands (hours, minutes, seconds) exhibit the time and fulfil chronograph functions to provide a time display of unrivalled simplicity. With its complex structure comprising 230 components and 5 bidirectional micromotors, the Calibre S offers unique functions:

- In time mode, reverse-movement date display with perpetual calendar applicable until 2099.
- Intuitive, easy-to-read chronograph with 1/100th of a second precision.
- Measures simple time, split time and two periods of time that follow at very short intervals.

An outstanding feat of technology, this exclusive electro-mechanical movement combines mechanical and quartz timekeeping to offer functionality unrivalled in three centuries of watch-making. No fewer than 230 components, including 5 bidirectional motors, ensure very high-precision functions.

Functions: The LINK Calibre S offers two operating modes: "TIME" mode and "CHRONOGRAPH" mode. Simply press the crown to change from one mode to the other. Use the central hands (hours, minutes, seconds) for intuitive, easy-to-read displays in both modes. The LINK Calibre S Chronograph dial has two half moon counters positioned at 4:30 and 7:30:
- In TIME mode:
Fitted with a perpetual calendar applicable until 2099, the counters indicate the date.
- In CHRONOGRAPH mode:
The left-counter indicates tenths of a second and the right-counter, hundredths of a second.

CHRONOGRAPH" mode enables the measurement of simple time, split time and two periods of time that follow at very short intervals.
The time can be displayed at any point during timekeeping by simply pressing the crown.
