Case and Crystal The 37mm stainless steel case features wide, faceted lugs that reflect the light beautifully, showcasing the distinct architectural style of late 1960s Seiko design.

The unique crown features an integrated hexagonal push-button, a signature of this specific reference. The crystal is clear and presents well, allowing for an unobstructed view of the dial. Movement Powering this watch is the high-grade Caliber 5106A automatic movement, boasting an impressive 33 jewels. This sophisticated movement is clean and visually appealing. Timegrapher testing indicates a daily deviation of between -57 and -61 seconds per day, which indicates a continuously running movement with a steady mechanical beat.

The strap is in excellent, unworn condition and complements the silver tones of the case and dial, adding a warm, vintage character to the overall presentation. Condition This timepiece is rated in Excellent vintage condition. The dial is the highlight, appearing exceptionally fresh and free from damage, with only small marks. The case retains its factory geometry and robust feel, though it bears the honest scars of history in the form of surface scratches and marks throughout the metal surfaces. The movement is clean, and the overall presentation is that of a well-cared-for survivor from 1967. Dimensions The case measures 37mm in diameter excluding the crown, offering a wearing experience that feels slightly larger than typical vintage dress watches due to the broad lug design. Remarks The "P" in Seikomatic-P stands for the unique "Push" date quickset system, an ingenious feature where pushing the hexagonal button in the center of the crown instantly advances the date. This 33-jewel variant is a highly collectible specification, bridging the gap between standard automatics and the Grand Seiko lines of the era. The presence of the original specific hex-crown adds significant value to this collector's piece.
