[Timestamp](https://imgur.com/a/0TNzFpJ) Up for sale is the iconic Seiko Helmet "Darth Vader" Chronograph from March 1977, reference 6139-7100. This legendary timepiece is powered by Seiko’s innovative Caliber 6139, one of the first automatic chronograph movements introduced in 1969. It features 17 jewels, a single 30-minute register at 6 o'clock, and a day/date indicator with Seiko's signature quick-set mechanism. Affectionately nicknamed the "Helmet," the bold, angular case design resembles a space helmet, making it a standout piece for collectors. The unpolished case showcases its originality, while the tachymeter bezel adds a practical touch for speed calculations. The black dial contrasts beautifully with vibrant yellow hands and an eye-catching yellow-and-cyan seconds counter. Paired with a hardlex crystal, this striking color scheme embodies Seiko's daring design choices of the era. 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.
