Thank you for viewing. This is the Crown Special, an upgraded model of the Crown, released with minor changes to the "First Grand Seiko." It's a model that features details similar to the "First Grand Seiko," such as a 14K gold-filled case, mountain-shaped Dauphine hands, and multi-faceted cut indexes. The 6 o'clock position features the "AD dial mark," indicating the use of SGP hard gold plating for the indexes. The movement is a hand-wound caliber with a hacking function. The leather belt is from SEIKO, but shows signs of wear. I purchased this in 2023 after it had been overhauled (disassembled and cleaned). Considering its age, I believe it's in good condition, but there is some aging commensurate with its years. There may be scratches and stains that are not fully captured in the photos. Please review the description and photos before considering a purchase. It is currently running well, but it is a product that is over 60 years old, so please purchase only if you understand this.
