Arceau Duc Attelé 

Haute Horlogerie and equestrian emblems meet and mingle in the Arceau Duc Attelé watch: a unique composition issued in a numbered limited edition featuring a central triple-axis tourbillon and a ‘tuning-fork’ minute repeater.

The association of these two major complications with a high-frequency movement is revealed at the heart of the watch. Housed in a distinctive 43 mm polished titanium or rose gold case, every technical and stylistic detail reveals its share of unexpected elements and meticulous care. 

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. 

Minute repeater

The dynamic striped guilloché decoration of the titanium model evokes the sound-wave propagation emitted by the minute repeater hammers sculpted in the shape of a horse. Chiming the hours, quarters and minutes, they strike the elongated U-shaped branches of the long hardened-steel ‘tuning-fork’ gong whose tones are reminiscent of cathedral chimes.

Equestrian-inspired mechanism

The Arceau Duc Attelé watch beats to a precise rhythm thanks to its Manufacture H1926 hand-wound movement equipped with a high-frequency balance (5 Hz). Its singular decor can be admired through a sapphire case-back.
The remarkable gears feature a cut-out design inspired by the wheels of the Duc attelé: a celebration of an image closely bound up with the name of Hermès and inspired by a drawing by Alfred de Dreux, which Emile Hermès acquired in 1920. 

The mainplate and bridges of Calibre H1926 feature an anthracite PVD treatment accentuating the light colour of the chiming mechanism, its horse head-and-mane racks and its toothed wheels. The openworked sapphire-crystal strikework bridge further enhances the sound of the minute repeater while revealing the movement's hand-finishing.
The watch is paired with a matt anthracite or matt abyss blue alligator strap crafted in the Hermès workshops.
