Dial and Hands
The exceptionally clean and attractive dial features a silver sunburst finish that remains very well-preserved. Applied indices and the Seiko and KS logos are bright and intact, complementing the crisp printed text which shows no visible loss. The Dauphine hands retain their black central stripes, though they display noticeable surface oxidation and spotting, particularly on the minute hand.

Case and Crystal
The stainless steel case retains its classic 'Grammar of Design' profile, remaining generally well-defined despite signs of regular wear. Honest wear consistent with age is present, displaying visible scratches and scuffs on the polished flanks and lugs. The smooth integrated bezel shows light scratches consistent with the rest of the case. The watch features its original KS-signed crown, which shows normal wear to the knurling and face. The flat crystal is clear with no significant scratches or chips, and the screw caseback engravings remain clear and fully legible.

Movement
Powered by the Seiko caliber 5625B, this 25-jewel automatic movement operates at a hi-beat frequency of 28,800 beats per hour. The movement appears clean with no obvious signs of corrosion or heavy oxidation, while the rotor and bridges retain their factory finishing. Engravings for Seiko, 25 Jewels, and Japan 5625B are clearly visible. Recording -15-18s/day on the timegrapher, it is exhibiting remarkable accuracy and consistency, performing brilliantly for a vintage timepiece.

Strap
The watch is fitted with a black textured leather strap that shows light wear and creasing.

Condition
Good vintage condition. The watch presents with honest wear consistent with age, notably visible scratches and scuffs on the stainless steel case flanks and lugs, alongside light scratches on the bezel. The dial is exceptionally clean and attractive, though the Dauphine hands display noticeable surface oxidation and spotting, particularly on the minute hand. The crystal is clear, and the caseback engravings remain fully legible. Supported by the recorded timegrapher result, the movement is performing very strongly.

Remarks
This King Seiko offers a highly legible and well-preserved silver sunburst dial paired with its original KS-signed crown. Driven by the robust automatic Hi-Beat caliber 5625B, it represents a strong example of Japanese watchmaking from the era.

History
The King Seiko 56KS series was produced by Suwa Seikosha and remains highly regarded by collectors for its impressive build quality and precision Hi-Beat movements. The 5625-7111 reference is characterized by its distinct screw case back featuring the KS lettering and its classic sharp case geometry. These models demonstrate Seiko's dedication to high-frequency automatic calibers during the early 1970s, providing a robust and elegant alternative to the Grand Seiko lines of the period.
