This King Seiko 4502-7001 features the manually wound, high beat (as marked on the dial) calibre 4502A. As part of the famous 45~ series of King Seiko movements, the 4502A runs in 36,000 bph, or 5 Hz, which provides greater accuracy to the wearer. The calibre 4502A also instituted an instantaneous date change for the framed aperture at three o'clock.
The gold-plated Seiko 4502-7001 carries the same sharp, disciplined design, but with a noticeably warmer and more expressive presence.

The case retains its crisp, angular geometry, yet the gold plating softens the edges visually, giving the watch a richer, more luxurious feel. Light plays differently across the surfaces, where steel feels cool and precise, the gold tone adds warmth and depth, accentuating the polished facets and brushing in a more understated, elegant way.

On the dial, the gold case pairs beautifully with lighter tones, often creating a subtle contrast that feels refined rather than flashy. The applied markers and dauphine hands, already sharply cut, take on an almost jewellery-like quality in this finish, catching the light with a gentle glow instead of a sharp gleam. The absence of lume keeps the look clean and uninterrupted, enhancing its dressy character.

A BIT OF TRIVA

The inter-corporate competition between Grand Seiko and King Seiko in the 1960s and '70s is a story that has fascinated all who have heard it. At that point in time, Seiko had two factories to create watches. Grand Seiko was produced at the Suwa factory; King Seiko was produced at the Daini factory. The rationale between having these two separate factories was to promote internal competition in order to build the absolute best watches possible. This 1970 King Seiko is an excellent example of exactly that.
The 45 King Seiko is the first 10-beat watch manufactured by Daini Seikosha Kameido Factory.

The 45 Kings became the new-generation 10 beat, thin high-end machines that were released and officially certified by the Japanese Chronometer Inspection Institute (Est 1968) As for the manufacturing method, the watch was assembled separately from the normal line, carefully adjusted and inspected before being cased.
The case features large lugs, and the linen dial is a wonderful design that gives a simple yet powerful impression. It is a masterpiece of its time, and still today its awesome.

OUR THOUGHTS

The 45 King Seiko is especially prized for its high-frequency, 36,000 vph hand-wound movement, celebrated for both its precision and build quality. Made during a period when Seiko’s in-house divisions were pushing each other to excel, it reflects a commitment to refined design and uncompromising mechanical performance. With its clean, understated styling, impressive accuracy, and place in Seiko’s history alongside its relative scarcity, it remains a standout choice for collectors in search of exceptional vintage Seiko craftsmanship.
