Seiko 7321-5410 – Vintage Ladies Quartz Dress Watch (October 1984)

Elegant rectangular Seiko quartz watch from the mid-1980s with the precise caliber 7321A , a flat quartz movement from the successful dress watch line of that time.

The 7321-5410 model impresses with its clean lines, gold-plated case and minimalist dial design, typical of Seiko's "Dress & Business" collections of the early 1980s.

The Seiko 7321A movement is a highly reliable, ultra-thin quartz caliber with low power consumption and an accuracy of ±15 seconds per month. Weighing only 11 grams including the strap, this watch is incredibly lightweight.

The case back shows the complete serial number 4Oxxxx , which dates the watch to October 1984 (first character “4” = year, second “O” = month October).
