Fans of Seiko have almost certainly heard the fascinating story of inter-company competition between King Seiko and Grand Seiko during the 1960s and 1970s. Back then, Seiko had two separate factories creating its watches, with Grand Seiko produced at the Suwa factory and King Seiko produced by the Daini factory. Seiko’s objective behind having its two factories compete against each other was to promote progress through competition, with the end goal of building the best timepieces possible.
Of course, while King Seiko put out some amazing and insanely cool watches in the 14-ish years they were producing, Grand Seiko ultimately won out the competition and has gone on to be the crowning jewel in the Seiko portfolio. And with pieces like the 4520-7000, part of the famed 45GS family, it's little wonder why. Taro Tanaka's "Grammar of Design" is alive and well here – just look at the angles and incredible polishing on the case. And that deep, inky blue dial is just begging to be stared at, regardless of what time it is. It also features a fantastic “Hi-Beat” movement, which refers to the manually-wound cal. 4520, which beats at a frequency of 36,000bph and offers truly remarkable precision.

CASE & BRACELET
The 35mm stainless steel case is in excellent overall condition and retains its crisp lines, sharp angles, and the distinct broad lugs that define Seiko’s Grammar of Design philosophy. It includes its original "GS"-signed crown. The case back features the gold GS medallion, and all the original markings are present and highly legible. Completing the watch is a 2-piece leather strap.
DIAL & HANDS
The original dark blue dial is in exceptional condition with a touch honest aging between 3 and 6 o'clock. The dial features thin, applied silver hour markers. All of the dial fittings, along with the faceted dauphine hands, are finished to Grand Seiko's exceptional standards, and since neither the dial nor the hands feature any luminescent material, there is nothing to interrupt their brilliantly polished surfaces.
ACCESSORIES
None. The watch is running and functioning correctly, though the service history is unknown. A movement service can be purchased upon request.
