This item has been professionally serviced, including a new battery, cleaning, polishing, disassembly and internal cleaning, and ultrasonic cleaning, a value of 20,000 yen. Seriously rare! This is an ultra-rare example of a SEIKOSHA (Seikosha) PRECISION pocket watch, commonly known as the "19 Seiko," believed to be a **very early model**. The SEIKOSHA logo, used before the SEIKO designation, was limited to the period immediately after the war to the early 1950s, making it exceptionally rare compared to later mass-produced items. As the prototype for JNR (predecessor of JR) railway watches, it was also used by the military and public institutions, making it a historical masterpiece. Currently unavailable for purchase new on the market, it's a highly sought-after item for antique collectors! 【Key Features】 ・Dial: Beautiful cream color (aged patina) with an exquisite hue! The contrast with the blue hands (blued steel style) is the ultimate vintage look. ・Old SEIKOSHA PRECISION engraving → Rare specification from the early 1950s (later unified to SEIKO) ・Small seconds hand with a classic layout for a genuine feel ・Comes with the original chain, retaining the heavy feel of the time ・Working Please refrain from purchasing if you are looking for a perfect, mint condition item. However, this is an ultra-rare piece that will appeal to true enthusiasts and vintage lovers who appreciate "authentic rust," "patina that tells a story," and "the joy of restoration." 【In Conclusion】 I love vintage watches and have a large collection, mainly of Japanese-made pieces. From my collection, I am offering this carefully selected, exquisite piece. I promise careful handling and packaging with sincerity. 【Notes】 Please understand that there may be scratches and stains that do not appear in the photos. The perception of the item's appearance and condition varies depending on individual subjectivity, so please refrain from purchasing if you are particularly sensitive, unfamiliar with used items, or a collector of new-like items. • I have inspected and confirmed the operation as carefully as possible, but due to the aging and individual differences of the items, there may be slight errors or oversights. We appreciate your understanding.
