Dial and Hands
The watch features a striking silver sunburst dial that catches the light beautifully, showcasing the meticulous finishing characteristic of late 1960s Seiko. The dial furniture includes applied faceted baton indices, with a prominent double baton at the twelve o'clock position, and an applied serif Seiko logo. The text SEIKOMATIC-P and DIASHOCK 33 JEWELS is crisply printed in black. A framed day-date aperture at three o'clock displays the day in Kanji, adding distinct domestic-market appeal. The faceted dauphine hands exhibit a subtle, honest oxidation visible under magnification, consistent with the age of the timepiece. The dial itself remains in exceptionally clean condition, with only minor edge discoloration present near the six o'clock marker, preserving a stunning overall aesthetic.
Case and Crystal
The thirty-four millimeter stainless steel case features a classic profile with brushed upper lug surfaces that transition cleanly into polished case flanks. The smooth polished bezel frames a classic domed acrylic crystal, which presents clearly with only faint surface micro-abrasions typical of vintage wear. The case retains strong lines and factory geometry, displaying honest, superficial scratches and scuffs commensurate with careful use over the decades. The distinctive faceted crown, designed for the caliber's unique push-quickset function, sits flush at three o'clock. The screw-down caseback is sharply engraved with the factory specifications, the reference 5106-7000, and a charming Kanji presentation engraving dated December 1967.

Remarks
The Seikomatic-P represents a fascinating era of Seiko's mechanical innovation, specifically with the introduction of the push-crown quickset date mechanism.

History
Introduced in the late 1960s, the Seikomatic-P line was positioned as a premium automatic offering, bridging the gap between standard automatics and the elite Grand Seiko and King Seiko ranges. The P designation highlighted the innovative push-button crown mechanism used to advance the date, a hallmark of the sophisticated 5106 caliber. With a high jewel count of thirty-three, these movements were designed for superior durability and precision. Today, the Seikomatic-P is celebrated by collectors for its elegant design language, advanced mid-century horological engineering, and enduring aesthetic appeal.
