SEIKO UFO 6138-0012, AUTOMATIC CHRONOGRAPH, 1977

The Seiko UFO is one of the most iconic models from the Japanese brand, officially known as Seiko 6138-0011/0012. Released in the 1970s, this automatic chronograph has become a true classic among vintage watch collectors thanks to its unique design, advanced technology for its time, and prominent role in the evolution of mechanical watches.

The nickname “UFO” comes from the shape of its case, resembling a flying saucer. The case, larger than most for its time (approximately 44 mm in diameter), features a rounded and robust design that anticipated current trends of larger watches. This design made it a bold and distinctive timepiece that didn’t go unnoticed.

Internally, the Seiko 6138-0011/0012 UFO is powered by the legendary caliber 6138, an automatic chronograph movement with a column wheel and manual winding function. This caliber was known for its precision and reliability, being one of the first automatic chronographs produced in series. The watch had two subdials: one for the minute counter and one for the hours, offering great functionality to users.

The UFO was not only a functional watch but also a symbol of Seiko’s ability to compete in the global market against Swiss brands, which traditionally dominated the watchmaking sector. Its popularity grew rapidly in Asia and other international markets, establishing Seiko as a benchmark in the industry.

Today, the Seiko UFO is a highly sought-after model by collectors and enthusiasts. Its combination of daring design, fascinating history, and reliable mechanical movement make it a must-have piece for those who appreciate vintage watchmaking.
