Description
For your consideration is a May 1974 6139-7070 “Mini Jumbo” Automatic Chronograph. This is the black dial variant and is in very good used condition.
Condition
The original dial and case back date stamps are both (45) and the dial and hands are all in excellent condition with the original luminous material still intact. All of the components of the watch are original and as they were from the factory. The case is in very good condition with minor scrapes on the case back as shown in the pictures. The crystal glass is a new aftermarket style, but the retaining ring is original.
The bracelet is an original and NOS Seiko 8056 mesh style adjustable clasp style bracelet and although not original to this model, it is a very appropriate accessory that suits the watch very well.

Service
I have fully serviced the movement of this watch. That process includes a full cleaning and evaluation of all movement components and proper lubrication plus the addition of two American made arbor port jewels. Lubricants used were Moebius synthetic varieties appropriate for this watch movement type. The case back, pushers and crown all have new, and factory correct seals.
This watch comes with a limited 1-year limited warranty on the movement from the time of sale. Shipping is to CONUS through USPS 2-day. International is a flat fee using USPS international priority.
