For sale is a Seiko 6138-3005 chronograph. The 6138-3005 is an uncommon sub variant of the Jumbos compared to the 6138-3002. This watch was serviced by John Sachs (Vette Enthusiast) in November 2022 over at the watch site forum. He regularly services vintage Seiko and is a well respected member of the community. You can see his work on the forum. This watch is in great condition for its age. The case is unpolished and all the case lines are nice and crisp. hard to find one that is in this condition. The watch will come with an Uncle Seiko tapered H link bracelet, East Tech end links with some extra links. I have included a photo of the listing of a jumbo sold on blairwatchproject.com a few months ago for $1450 as a price reference. Considering the nice condition and servicing cost for these 6138 chronograph, I think the price is fair. Dimensions: 42mm case, 14mm thick, 46mm l2l, 19mm lug width.
