TAG Heuer has developed a revolutionary piece of technology, the Isograph: a proprietary state-of-the-art oscillator featuring a carbon composite hairspring and tailor-made balance wheel for high chronometer precision.
Inspired by the aeroplane cockpit, the 42mm Autavia dial features a SuperLuminova® luminous index to ensure its three hands are legible day and night, whatever the conditions. In homage to the first Autavia watches from 1933 to 1957 which were fitted to the racing car and aeroplane dashboards, the crown features a retro design for optimal ease of use. All Isograph-equipped timepieces are chronometer-certified and offer improved accuracy despite disturbances such as shocks, temperature fluctuations, and magnetic fields.
Featuring a tyre and a propeller, the engraved case back is a nod to the collection’s heritage. Its geometry is evocative of an aeroplane propeller while the movement is protected by a highly resistant layer of steel. The case material is in Stainless Steel or Bronze with Ceramic or Steel Bi-directional external bezel.
The TAG Heuer Autavia Isograph utilizes the Sellita SW200 (the Calibre 5 in TAG speak) and TAG brings it up to chronometer-certified spec. It adds a carbon-composite hairspring bringing with it some serious anti-magnetic and shock properties. The hairspring is made in-house and the “Isograph” name symbolizes the use of such technology.
