A bold 1970s Heuer Calculator, powered by the automatic Calibre 12 chronograph movement. Built around Heuer’s technical slide-rule bezel, the Calculator was designed as a wrist-worn tool for quick arithmetic and timing calculations. This example features the signature oversized stainless-steel case, deep blue dial, orange chronograph hands, twin-register layout, date window, and rotating calculator bezel. One of Heuer’s most distinctive 1970s chronographs, it captures the brand’s experimental tool-watch design language at its peak
