CITIZEN SEVEN STAR Ref. 2812-Y, Made in 1968 Day-Date Diver 100m 21 Jewels, Blue Dial, Automatic (with manual winding function) Wrist size: Approximately 19cm No issues with the movement in any areas. The back cover shows some signs of use, but the engraving is still clear. *The serial number has been masked to prevent unauthorized image use. The watch is fitted with a valuable Citizen genuine bracelet, with an engraving on the clasp. There is a small chip on the crystal, but it's not deep enough to catch a fingernail. *See image 8, marked with ⭕️. The luminous paint is dim compared to modern watches, but it all glows properly. I usually display it carefully in a glass case. It's an antique from over 50 years ago, so I handle it with care. I think this is a truly recommendable level for those looking for this model. The crown at the 2 o'clock position is for rotating the inner bezel. The crown at the 4 o'clock position winds the mainspring. Pulling it out one step changes the calendar and day of the week. Pulling it out two steps allows you to set the time. It's a beautiful watch in good condition, but as it is an antique, please refrain from purchasing if you are looking for a new-like product or are overly sensitive. Due to the high value of the item, I will film a video of the packaging process at the Yamato Transport office parking lot and keep it until the transaction is complete. Returns are not accepted to prevent swap fraud.
