Read the description carefully!
Serviced, Rare 1979 Seiko Grand Quartz high accuracy twin quartz in fair condition.
Completely disassembled and cleaned, including the movement.
Original Sapphire crystal is intact, no chips nor scratches.
White dial with diagonal crosslines is clean and almost flawless if not for a stain on the edge at 27 minute mark.
Stainless steel case has some scratches and nicks.
Caseback is in good condition.
Main problem with the watch is its original stainless steel bracelet. Visually, it looks pretty good, with solid steel links tightly connected. However, I was not able to remove it from the case and I couldn't push out a single pin out of the links in order to size IT. They seem to be completely seized due to corrosion.
It is sized for 19cm wrist.
ONLY BUY IF YOUR WRIST IS SMALLER THAN 18CM OR YOU FEEL CONFIDENT THAT YOU CAN SIZE IT.
New battery and rubber gaskets.

Customer Reviews
The watch came in much faster than I expected. Once I opened the box and saw the watch, it was immaculate. The pictures shown on the website were accurate when showing and defects (small stain on dial edge at 27 minute mark). The description of the watch was precise as well. What surprised me was how the watch still shined like new. I couldn’t be happier. I reached out with a question after I received it and was responded to quickly and got great service. I’ll definitely be buying another watch in the future from TokeiMedic
