SOLD — Seiko 6138-8020 Panda



For your consideration is a May 1974 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. It comes on the original Z027 Seiko 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 that is the same as the case stamp (45 — 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 08/26/2022. 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.
