It patented the oscillating pinion in 1887, a chronograph coupling still in use today, made its name with dashboard timers for motoring and aviation, then introduced the \u003cem\u003eCarrera\u003c\/em\u003e in 1963. On 1 January 1964, Ed. Heuer \u0026amp; Co merged with Leonidas, another Saint-Imier house that had become Switzerland's leading supplier of sports timers to the American market; movements carried the Heuer-Leonidas SA signature from then on. That merger produced a range of chronographs aimed at a wider public, positioned below the \u003cem\u003eCarrera\u003c\/em\u003e and \u003cem\u003eAutavia\u003c\/em\u003e ranges: chrome-plated cases with steel backs, cam-actuated Valjoux calibres, direct two-register reading. Until 1985 these watches carried the Heuer signature alone, before the company became TAG Heuer.\u003c\/p\u003e\n\u003ch3\u003eCharacter\u003c\/h3\u003e\n\u003cp\u003eThe registers are snailed in concentric circles, the only texture on an otherwise matt dial. At twelve the index doubles, marking where the reading begins. Beneath the tachymeter runs a fifth-of-a-second track — exactly the rate at which the calibre beats.\u003c\/p\u003e\n\u003cp\u003eServiced. Patina and wear visible.
