The 61GS series launched in 1967 and there were a vast variation of models that were produced throughout the production run of the series (51 models in total) that lasted until 1975.

This is an all original vintage 6145-8000 Grand Seiko employing the famour G.O.D (grammar of design) case design first introduced in the 44GS.

Overall, this piece is in great vintage condition. The case has some light scratches but we believe it has just been polished a couple of times in the past given that it retains sharp edges with a beautiful Tanaka grammar of design profile. The original silver/white dial is in very clean condition with just some minor blemishes along the edge of the dial but nothing major. The handset and crown are all original and in good condition. The original caseback and the gold medallion is in great condition with  some slight loss of gold in the gold medallion. The movement was just serviced by our watchmaker in February 2021 and is running at -5.2 seconds per day.
