We have received a "Seikomatic Selfdater" equipped with a 39-jewel automatic movement. The Cal. 395 movement featured in this model is an upgraded version of the 24-jewel Seiko automatic movement, which was the first to include a calendar mechanism. It is also the first automatic movement to feature a hacking function (seconds hand stop mechanism)

The watch boasts a refined, silver sunburst dial with an applied spinning top logo. The indices are made of solid gold, providing a luxurious feel to the SD dial. The case back is a unique 10-sided design with dolphin and crown engravings, indicating a high-end water-resistant specification capable of withstanding depths of up to 50 meters.

While there are some minor scratches on the exterior, there are no noticeable damages, and the engravings on the case back are still clearly visible. As this is a full automatic model without a manual winding function, please swing the watch to wind it before wearing.

It has a genuine buckle of this model, which is rare.
The strap is original from the period and has some deterioration.
