The year of manufacture is confirmed by the case back serial number “973191”, following Seiko’s official serial dating system (September 1979). The watch features a distinctive tonneau-shaped stainless steel case and an original Seiko dial with natural age-related patina, showing visible lacquer cracking consistent with vintage Japanese watches of this era. This characteristic gives the watch a strong wabi-sabi aesthetic that is highly appreciated by European collectors. The original Seiko stainless steel bracelet, signed “The Maruman / BS12D / Japan”, is still present, which significantly enhances collector value.
