The model 6556 was called the "Trubeat" and the "Metropolitan" depending on the market they were sold in. The "dead beat" second movement was introduced on wristwatches during the 1950s and many companies ranging from Doxa to Longines also produced such watches. Based on the systems used in Marine Chronometers the "dead beat" escapment was claimed to enhance readability. The model name would usually be on the dial but this has been replaced.
