CITIZEN Citizen - Challenge Timer Automatic Chronograph This is an old watch. Details are unknown. If you wind the mainspring, it works properly, including the chronograph, but it has not been maintained, so please consider it as-is. There is a feeling of use, so this is limited to those who understand. (No claims, no returns) Regarding the appearance, the black paint on the bezel around the crystal is peeled off all around. Other than that, the dial is relatively clean. 【Important】 Regarding the day-date, the adjustment (done by pulling the crown one step) is for the date ◯ and the day of the week ▲. Currently, the day of the week is in "another language" (German?) and not English. Because the day of the week cannot be adjusted with the crown, it has been used in the aforementioned other language. The automatic changeover occurs for both the date and the day of the week. The day-date malfunction likely requires an overhaul. Thank you for viewing.
