Tag Heuer became a celebrated sporting and racing watch manufacturer back in the 1880's. Heuer developed and patented the first oscillating pinion which simplified the Chronograph and is still widely used today. This precision for timekeeping in sports, which included the first dashboard stopwatch for racing cars, continues today and Tag Heuer has a large selection of watches and is one of the world's leading luxury brands. Now available at Watches of Mayfair.
