Presented here is the Citizen Seven Star Deluxe 23 Jewels, Ref. 4-520173TA. Launched in the 1970s, the Seven Star collection was originally targeted at young professionals. Despite being positioned as an accessible line, the series featured a vast array of specifications and designs. Today, it remains a favorite among collectors due to the existence of rare variations that are seldom seen on the market.

This particular model is the "Deluxe," a higher-tier version within the series. It features a sophisticated brushed grey dial paired with multi-width bar indices and sleek baton hands. The unique vertical day-date display at the 6 o'clock position adds a distinctive touch of character. The design is further elevated by a fixed inner chapter ring, providing a luxurious and classic aesthetic. The stainless steel case sports a soft, rounded tonneau shape and features a "C" marked crown. The screw-back case ensures durability and airtightness. It comes equipped with an authentic Citizen stainless steel bracelet. This timepiece is a masterpiece of 1970s Japanese vintage design, condensing Citizen's technical skill and aesthetic philosophy into a watch that remains stylish even today.
