Seiko Automatic Day-Date Watch Head (Movement 7009-8331 F)

The item is a standalone watch head, specifically a vintage Seiko automatic day-date model, identified by the visible caseback markings. The case appears to be made of stainless steel, consistent with the additional context provided. It measures approximately 35-40mm in diameter, judging by its proportion in the hand, and features a classic circular shape with integrated lugs, though the spring bars for a strap are absent. The crystal covering the dial is heavily scratched, scuffed, and appears to have significant internal or external fogging/discoloration, obscuring clear visibility of the dial beneath. The dial itself is severely discolored and corroded, exhibiting a mottled yellowish-brown hue with dark spots, suggesting extensive moisture damage or prolonged exposure to harsh conditions. The hour markers are largely obscured, although some faint metallic indices might be discernible. The watch hands, including hour, minute, and a possible second hand, are present but also heavily corroded and almost indistinguishable against the degraded dial. A day and date window is visible at the 3 o'clock position, but the characters are illegible due to the overall deterioration. The watch crown is missing. The case itself shows significant wear, corrosion, and scratches, indicating considerable age and lack of maintenance. The lugs are intact but show signs of dirt and grime accumulation. Based on the movement number '7009-8331 F' and the 'Japan-SC' designation, along with the '044693' serial number, this watch likely dates from the late 1970s to early 1980s. The overall condition is extremely poor; it is non-functional and requires extensive restoration or can be considered for parts. The craftsmanship, though originally high-quality for Seiko, is now overshadowed by severe degradation.
