SOLD - Seiko Speedtimer 6138-8010 Holy Grail






Introducing one of the most beautiful JDM Chronographs from the 6138. The Seiko 5 Sports Speedtimer 6138-8010. Nicknamed the Holy grail, it is one of the hardest Speedtimer models to hunt for as they rarely show up for sale, and finding a good example is even rarer.


The iridescent blue dial is striking and has a faceted 2D shape with the mirrored layer connecting both hour and minute registers. The chronograph hands have retained its original bright orange and lumed baton hands which stand out beautifully against the surrounding the Tachymeter ring and the thick bezel.


The case is 42mm which makes it thicker than other Speedtimer models, yet it has a very good presence on the wrist.


The bracelet is unique for this model: Coded XjA231 on the end links, it's vertically brushed and wears comfortably on the wrist.


Observing this beautiful example, you might get hints of other Seiko Panda models such as the 6138-8020 and the JDM Baby Panda 6138-800X series. You're actually right, this was initially designed by the same designer who created one of the most iconic pieces by Seiko such as the Pogue, Bruce Lee, and the Panda/Baby Panda models.


If you're looking for the holy grail, this is one of the best-preserved models you can probably find on the web and it will make a great addition to the collection.
