June 1978 – Seiko 6138-8021 Panda. Serviced and Guaranteed 100% original

Price: (SOLD)

For your consideration is a June 1978 6138-8021 “Panda” Automatic Chronograph. This is probably one of the most desirable Vintage Seiko Chronographs. All components are 100% original to the watch (dial, hands, and all mechanical components). I have replaced the crystal, but I will include the original crystal with the sale.

History of the Watch

This 6138 is part of my personal collection of watches. I do not know the origin before my ownership. Two prior services. I serviced this watch in the last week and it is running perfectly.


The watch is completely original unto itself and I would rate the cosmetic condition as a 9.5/10. The case is unpolished and shows age and wear commensurate with a 40+ year old watch. The dial is original to the watch and has a date stamp one month prior to the case date (85 – see images). The dial is the most amazing linen pattern with the beautiful off-green subdials. The dial and hands retain the very clean factory applied lume. The hands reset exactly to their vertical positions. Bracelet is an original Seiko with the original end links and shows some minor imperfections


I serviced this watch ~1 week ago. 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 240-250 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.
