SOLD – NOS 6139-7039 Mini-Jumbo




For your consideration is a New Old Stock (NOS) March 1972 6139-7039 Mini-Jumbo / Seiko Speedy Automatic Chronograph — perhaps one of the only NOS watches you will find from this era. All components are 100% original to the watch (dial, hands, case, bracelet and all mechanical components).

History of the Watch

This 6139 is part of my personal collection of watches. I do not know the origin before my ownership. I just serviced this watch and it is running perfectly (more below).


The watch is completely unworn and original unto itself and I would rate the cosmetic condition as a 10/10 — It really is perfect. The case is has never been out of a box and this watch has never seen any time on the wrist. It is a “double sticker” caseback and retains the blue tinted cover and the inspection sticker, though the text has faded on the inspection sticker. The hands reset exactly to their vertical positions. Watch comes as a head only, but I do have bracelets and bands if you want.


I serviced this watch on 02/26/2021. That process includes a full cleaning and evaluation of all movement components and proper lubrication. Lubricants used were Moebius synthetic varieties appropriate for this watch movement type. The amplitude numbers are 230-240 range and the rate is +/- 2 sec/day. The case back, pushers and crown all have new, and factory correct seals.

This watch comes with a 100% money back promise of originality and a 1-year limited warranty on the movement from the time of sale. At that price, shipping is free CONUS through USPS 2-day. Sorry, domestic buyers only at this time.
