Zenith Heritage 146

Zenith is presenting a new vintage series: the Heritage 146 chronograph inspired by a 1960s watch and now equipped with an El Primero movement. It features a retro look, a tropical brown or blue dial, a 38 mm-diameter steel case and a column-wheel El Primero movement chronometer. Subtly reinterpreting an historical model, the Heritage 146 is a unique offering combining the best of the Manufacture’s past: design, history and true rarity.

The 1960s model was equipped with Calibre 146D featuring a balance-wheel oscillating at a rate of 18,000 vibrations/hour, ensuring a 38-hour power reserve and displays of the hours, minutes, with small seconds at 9 o’clock.
Like the HODINKEE limited edition in 2016, the new Heritage 146 offers a chronograph with central sweep-seconds hand and 30-minute counter at 3 o’clock, as well as a tachymetric scale. This two-counter dial without a date window reflects a configuration typical of 1960s chronographs.
The case of this exclusive edition now frames two dial options: tropical brown or blue sunray-patterned with rhodium-coated baton hands. However, its key difference lies in the fact that it beats to the lively rhythm of 36,000 vibrations per hour, dictated by the automatic high-beat El Primero Calibre 4069.
Regulated and adjusted to meet chronometer standards, this 254-part column-wheel chronograph calibre – wound by an oscillating weight adorned with “Côtes de Genève” – drives an extremely accurate tenth-of-a-second display and has an over 50-hour power reserve. Its high-frequency mechanism is housed in a 38 mm-diameter vintage-style steel case that is water-resistant to 50 meters and features a fluted crown as well as two round pushers.
The screw-down sapphire crystal caseback has an anti-reflective treatment on both sides. The final touch is set by a racing-style strap in a choice of brown or blue rubber-lined calfskin leather.
