Seiko 5626-7113: What Matters Before You Buy

The 5626-7113 belongs to the 1973-1974 King Seiko range established by the watches handled here. Its automatic caliber 5626B drives a day-date display, and known examples combine that practical calendar with dauphine hands carrying black central stripes. This is a precise, formal daily watch rather than a sports case disguised by a silver dial.

At 36 mm excluding the crown, the case wears compactly, but its angular surfaces give it more presence than a round case of equal width. The silver sunburst finish changes with light, while applied indices and black-striped hands preserve legibility. Exact thickness is not established by the available evidence, so cuff clearance should not be claimed from measurements we do not have.

The dial takes priority because damage around the applied KS emblem is conspicuous and cannot be treated as attractive patina. We have handled examples ranging from clean silver surfaces to significant dark corrosion around that emblem, with lesser faults including edge wear, spotting and trapped debris. Between a sharp watch with light edge ageing and a brighter redial, take the sharp watch with its period dial intact.

Case geometry comes next. Distinct brushed and polished planes, crisp transitions and defined facets carry the design, while polishing makes those boundaries soft and cannot be reversed by servicing. A signed crown and English and Kanji day wheel strengthen a coherent example, but neither proves that every component left the factory together. No production total is established, so rarity claims for the reference or a particular day wheel are not justified.

Handled 5626-7113 examples date from 1973 through 1974, which is the bounded production range supported for this reference here. The broader caliber 5626 production window runs from 1968 through 1975, but that window dates the caliber family rather than every watch carrying it. It should not be used to stretch the reference beyond the years established by complete examples.

A movement marked 5626B is the expected mechanical match for the 5626-7113 watches described here. The service history remains unknown unless dated documentation accompanies the individual watch, and a timegrapher result alone does not establish what work was performed. Without such paperwork, the movement's identity and current performance can be stated, but its prior maintenance should not be guessed.
