Seiko 5 Sports SpeedTimer 6139-8040






The Seiko 5 Sports SpeedTimer Ref.6139-8040 is the ultimate choice for those seeking a vibrant yet understated 6139 variant. Its distinctive case styling, characterized by rolled hooded lugs, tapered corners, and impeccably flared edges, is simply perfect for any wrist size. The subtly inset bezel frames the original hardlex crystal, unveiling a vibrant blue purple sunburst dial that effortlessly captures attention. 


What we love about this one is its immaculate condition as the original finishes on the case and bracelet are still visible without compromising on the immaculate condition of the dial and hands.

This 6139 variant not only exudes aerodynamic design but also retains its original price tag and comes complete with an instructions manual, which is really the icing on the cake.

The watch currently works flawlessly and it will be sold as-is. Please let us know if you wish to service it.
