Ask any vintage Citizen fan to name one of the most coveted chronographs, and chances are they’ll point you straight to the “Speedy.” Nicknamed for its striking resemblance to the legendary Omega Speedmaster.
Originally available only in Japan, this reference captivates with its sharp dial layout and an outer tachymeter scale bezel insert that instantly grabs attention. While you might assume that all these design elements would create visual chaos, Citizen somehow makes it all work beautifully. The result? A clean yet bold aesthetic that strikes the perfect balance between utility and flair. The case itself is a work of art: Brushed and polished in all the right places, creating subtle contrast and a sleek, compact form tailored for Japanese wrists.
But this watch isn’t just a pretty face. Under the hood is the legendary in-house 8110A movement: a high-beat, 28,800 vph automatic chronograph with flyback functionality. It features both day and date displays and can be manually wound.
Though also offered in a white dial, this black dial version is the one to beat, and it comes factory-fresh. Completely unworn, it still has its original tags and instruction manual, waiting to start its journey with a new owner. A true masterpiece of Japanese craftsmanship, “Made in Japan” through and through, and ready for its next chapter.
The watch currently works flawlessly and will be sold as is. Please let us know if you wish to service it.
