A stunning example of this rarely seen Grand Seiko that combines a super funky 1970's vibe with exquisite styling and a fabulous movement. I'll let the photos speak for themselves but the graduated green dial is flawless underneath it's new, very hard to find 9 faceted crystal. The case and case back are in fantastic condition, never machine polished and the GS medallion is as close to mint as they come. Freshly serviced by our master watchmaker and running at Chronometer grade accuracy.
