Lanco Ref. 53010, Cal 2481

In the 1970s, Lanco (short for Langendorf Watch Company) continued to produce a wide range of high-quality watches, including both mechanical and quartz models. The company was known for its innovative designs and technologies, including the "Dynotron" movement, which used a battery-powered oscillator for improved accuracy. During this period, Lanco produced a variety of watches, from dress watches to sports watches. One notable model was the Lanco "Super Compressor," a diving watch that was water-resistant to depths of up to 600 feet (180 meters). The watch featured a patented "Super Compressor" case design that increased water resistance as the pressure increased, making it a popular choice among divers and watch enthusiasts. Lanco also produced a number of chronograph watches in the 1970s, including the Lanco sport chronographs. These watches were highly accurate and reliable, with precise timing and a range of functions, including stopwatch, date display, and tachymeter. Despite its reputation for quality and innovation, Lanco struggled to compete with larger Swiss watch brands in the highly competitive watch market of the 1970s. The company was eventually absorbed by the Swiss watchmaking conglomerate ASUAG (Allgemeine Schweizerische Uhrenindustrie AG) in the 1980s, and the Lanco brand was eventually phased out. However, vintage Lanco watches from the 1970s remain highly sought after by collectors and enthusiasts for their quality, design, and innovative technology.
