SOLD — Seiko 6138-8020 Panda



For your consideration is a September 1977 6138-8020 “Panda” Automatic Chronograph — perhaps one of the most desirable Vintage Seikos. The body of the watch including the dial, hands, case, and all mechanical components are all original and it comes on a vintage Corfam Strap, but I have aftermarket correct bracelets available. Please let me know prior to purchase if you’d like to add the bracelet.


Diameter: 41mm
Width (L-to-L): 51mm
Height: 15mm
Lug width: 19mm


The watch is completely original unto itself and I would rate the cosmetic condition as excellent. The dial and hands are original to the watch and the dial back has a date stamp one month prior to the case stamp (78 — see images). The dial is the most amazing champagne linen pattern with the beautiful off-green sub-dials. The dial and hands retain the very clean factory applied lume. The hands reset exactly to their vertical positions. The crystal is a new acrylic Sternkreuz, which is an exact reproduction.


I serviced this watch on 07/29/2022. 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 values 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. Shipping is to CONUS through USPS 2-day. International buyers must contact me for a shipping quote.
