The Seiko Helmet Darth Vader ref. 6139-7100 chronograph begins in 1969 when the first three, automatic chronographs emerged. The calibre 11, the el Primero and the Seiko 6139 movement. The Seiko caliber 6139 is an automatic chronograph with a single thirty-minute register at 6 o'clock and day/date indicator. It has a unique quick set date function; to set the day you push the crown in all the way until it changes. To set the date you press it a bit more gently, very ingenious. There is no continuous second’s hand on the watch, which takes a moment to get used to. The Seiko Chronograph Automatic, model 6139-7100, also affectionately known as the "Helmet" due to its unique case shape that's reminiscent of a space helmet. This iconic timepiece isn't just a watch; it's a significant chapter in the history of automatic chronographs, marking Seiko's innovation in the watchmaking world. The "Helmet" features a distinctive case design, not just for aesthetics but for ergonomics and protection of the crown and chronograph pushers. Its bold, angular shape captures the essence of the era, making it a standout piece for collectors and enthusiasts alike. The tachymeter scale on the bezel, a tool for measuring speed over a known distance, adds a layer of functionality for the sporting gentleman. 🔹Features ▫ Automatic Chronograph ▫ 17J Automatic Cal. 6139 Movement ▫ Tachymeter Scale ▫ Day/Date Display ▫ Stainless Steel Case & Bracelet ▫ Hardlex Crystal ▫ Baton Hands and Stick Indices ▫ Screw down Case Back ​ 🔹Dimensions ▫ Case Size: 40 mm ▫ Case Thickness: 14 mm ▫ Lug Width: 19 mm 🔹 Normal to none signs of wear.
