The new tourbillon chronograph models come in two classic versions crafted in pink gold or stainless steel with a white or black lacquered dial, and a contemporary version in brushed titanium with a slate grey dial.
The tourbillon complication is associated here with a legendary movement: the El Primero automatic chronograph calibre beating at the high frequency of 36,000 vibrations per hour. Its distinctive asymmetrical architecture places the tourbillon at 11 o’clock. It rotates once a minute and also incorporates a small seconds display and a patented date display appearing on a disc placed around the circumference of the tourbillon carriage.
The 45 mm-diameter case, crafted in pink gold or stainless steel for the two classic versions and water-resistant to 100 metres, is enhanced by a fluted winding crown and two round vintage-style pushpieces. The cambered sapphire crystal, glareproofed on both sides, ensures optimal legibility of the white or black lacquered dial punctuated by luminescent facetted dagger-type hands and hour-markers. The slim central chronograph hand, blued on the pink gold version and bearing the Zenith star emblem, sweeps accurately around the graduated dial circumference and its inner bezel ring bearing a tachymetric scale. The 30-minute and 12-hour counters are positioned at 3 and 6 o’clock so as to ensure optimal clarity. The sapphire crystal caseback let see the automatic El Primero movement and its gold oscillating weight adorned with a “Côtes de Genève” motif.
The titanium version features cut-out lugs and slender pushers giving it a resolutely sporty, modern touch. The brushed dial is slate grey, while the facetted hands and hour-markers are coated with a black luminescent material and the chronograph counters are framed by an anthracite grey rim.
The tourbillon chronograph movement El Primero Calibre 4035D was designed, developed and produced by Zenith. It features all the signature characteristics of the El Primero collection, beats at the exceptional frequency of 36,000 vibrations per hour enabling tenth-of-a-second precision. Comprising 381 parts, it is endowed with a 50-hour power reserve.
These three El Primero Tourbillon models are fitted with a rubber-lined black or brown alligator leather strap fastened by a triple folding clasp.
