Triple-axis tourbillon
On the dial side, a sapphire dome tops the triple-axis tourbillon and its triple mirror-polished titanium carriage shaped with two interlaced "Hs", symbolizing the union of Émile Hermès and Julie Hollande in 1900.
This tourbillon features three separate axes and rotation speeds (one full turn in 300, 60 and 25 seconds) and operates within a curved, eccentric hour-circle.
The hours-minutes display is punctuated by Arabic numerals inclined like a galloping horse. Claw-shaped hands appear around the rim of the chapter ring. Their blue hue complements the 48-hour power-reserve indicator appearing at the base of the dial.
