Seiko King Seiko ChronometervsSeiko King Seiko KS1969

Seiko King Seiko Chronometer 5626-7170 owners praise its rare grey and "Superior Chronometer" dials for their depth and sunburst finishing, which are best appreciated in person. The 36mm case is noted to wear slightly larger due to its lugs. The 5626 movement is recognized as a higher-grade chronometer-adjusted caliber than the 5606, keeping accurate time. A known issue with the 5626 movement is the quick-set date function's susceptibility to failure due to a plastic part, with no replacement part developments reported. On balance, owners value the Seiko King Seiko Chronometer 5626-7170 for its distinctive dial finishing and chronometer-grade movement, despite the potential date function issue.

Seiko King Seiko KS1969 owners and reviewers note its polished 39.4mm case and era-appropriate bracelet, with finishing that rivals Grand Seiko quality. The 6L35 automatic movement is described as a slimmed-down version of the 8L35, and its tonneau-shaped case with sloping sides makes it wear thinner. However, the price, cited between $1900 and $3200, is a point of contention, with some finding it overpriced and questioning its value proposition between Seiko and Grand Seiko. Accuracy from the 6L35 movement is reported as +15/-10 seconds per day. Some owners feel the new case shape, dial colors, and end links deviate from the classic King Seiko aesthetic. Overall, owners and reviewers find the Seiko King Seiko KS1969 well-finished but question its pricing and adherence to vintage design cues.
