Presented for auction by Second Vintage This Seiko Seikomatic-P is a remarkable example of late 1960s Japanese horology, combining a high-jewel count automatic movement with the innovative engineering that defined Seiko's golden era. The "P" in the model name stands for the unique push-button date quickset mechanism, a feature that set this reference apart during its production. With its clean silver sunburst dial and robust stainless steel construction, this timepiece offers a sophisticated aesthetic that bridges the gap between mid-century dress watches and everyday ruggedness. It stands as a testament to the Daini Seikosha factory's capability to produce elegant, high-performance wristwatches. Brand: Seiko Model: Seikomatic-P Reference Number: 5106-8020 Serial Number: 7602587 Movement: Seiko Caliber 5106A Automatic, 33 Jewels Dial: Silver sunburst with day and date indication Case Size: 39 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1967 Condition: Good vintage condition. The watch shows honest signs of wear consistent with its age, particularly on the case, while the dial remains in attractive condition. The movement is functioning with a timegrapher reading of -20 to -25 seconds per day, indicating healthy movement mechanics. Dial and Hands The watch features a refined silver sunburst dial that catches the light beautifully. It is adorned with applied multifaceted silver baton hour markers and a framed day-date window at the 3 o'clock position. The "SEIKO" and "SEIKOMATIC-P" logos are crisp and legible, accompanied by the Daini lightning bolt symbol above the 6 o'clock position. The silver dauphine hands are sharp and maintain a classic profile. The dial surface is generally well-preserved, showing only very minor signs of aging that do not detract from its overall elegance. Case and Crystal The stainless steel case features the distinct geometry of the late 1960s, offering a substantial presence on the wrist. The case surface shows visible scratches and marks consistent with normal vintage use, particularly on the bezel and lugs, retaining its original unpolished character. The unique recessed crown, designed for the push-button date quickset, is original and correct for this reference. The caseback displays the "Horseshoe" layout with clear engravings of the reference 5106-8020 and serial number, along with the "Water Proof" designation typical of pre-1970 models. The crystal shows light wear but remains clear and serviceable. Movement Powering this timepiece is the impressive Seiko Caliber 5106A, a 33-jewel automatic movement. This caliber was a high-specification engine for its time, featuring a unique quickset date system activated by pressing the crown. The movement is currently running within vintage tolerances, with timegrapher results showing a rate of approximately -20 to -25 seconds per day, offering reliable vintage performance. Strap The watch is fitted with a distinctive reddish-brown leather strap featuring contrasting yellow stitching and a geometric pattern. The leather is supple and complements the silver tones of the dial and case, adding a warm, vintage character to the overall presentation. Condition This timepiece is in good vintage condition. It presents an honest and original appearance with case wear that tells the story of its history. The dial is the highlight, remaining clean and attractive. The movement is mechanically sound, as evidenced by the provided timegrapher data. Dimensions The case measures 39 mm in diameter excluding the crown, offering a modern wearing experience that is slightly larger than many standard dress watches of the era. Remarks The Seikomatic-P is a collector favorite due to its interesting 33-jewel movement and the quirky yet practical push-date feature. Finding one from 1967 with such a clean dial is a distinct pleasure for the vintage Seiko enthusiast. History Produced in June 1967, this Seikomatic-P hails from a pivotal time in Seiko's history, just prior to the quartz revolution. The Seikomatic line was the tier just below Grand Seiko and King Seiko, often serving as a testing ground for automatic movement technologies. The 5106 caliber inside is highly regarded for its complexity and build quality, representing the peak of mass-market mechanical watchmaking from Japan during the 1960s.
