SEIKO SUPER 15 Jewels Manual Wind Mechanical Super Anti-Shock Red Movement

Product Description:
Brand, Manufacturer: SEIKO
Color: Case is silver. Dial is white. Indices are gold.
Size: Approximately 31mm.
Year of Manufacture: 1950s

Product Condition:
Usage Status: It is operational. It was overhauled in 2025, but the daily difference was a loss of 4-5 minutes at that time. I was fine with that as it was a small workshop run by my grandfather alone. It is still in that condition.
The movement is the red movement. It runs for approximately 35 hours when fully wound. It is currently operating well and energetically, but as it is an antique watch, I cannot guarantee its operation upon arrival.

The SUPER series is known for its diverse dials, but this unique dial with its unusual numeral placement is extremely rare. As shown in the images, the case is beautiful for its age. There are faint age-related stains across the entire dial. The strap is a black leather strap. It is clean but shows some signs of wear.
Thank you for looking.
