Up for sale is the iconic Seiko Helmet Darth Vader Chronograph from September 1976, reference 6139-7100. The Seiko Helmet Darth Vader chronograph traces its roots back to 1969, a pivotal year in the world of watchmaking when the first three automatic chronographs emerged. Among them were the Calibre 11, the El Primero, and Seiko's own Caliber 6139. The Seiko Caliber 6139 is a notable 17 jewels automatic chronograph movement featuring a single thirty-minute register at 6 o'clock and a day/date indicator. It boasts a unique quick-set date function: to set the day, you push the crown all the way in until it changes; for the date, a gentler press will do. The watch is affectionately known as the "Helmet" due to its distinctive case design, reminiscent of a space helmet. This bold, angular case not only makes a strong visual statement but also captures the essence of the era, making it a standout piece for collectors and enthusiasts alike. The tachymeter scale on the bezel provides a practical tool for measuring speed over distance. This model features a hardlex crystal, a black dial that contrasts beautifully with yellow hands, and a striking combination of yellow and cyan for the seconds counter. The unique color scheme really pops, making this watch a standout addition to any collection. This piece perfectly showcases Seiko's innovative spirit in the world of automatic chronographs. Overall, the watch is in very good condition. Some wear can be seen on the case, consistent with its age, as it has remained unpolished since the day it came out of the factory.
