A striking vintage Seiko 5 automatic timepiece featuring a distinctive square polished stainless-steel case framing a deep black dial enhanced by sparkling crystal-set hour markers. The geometric case profile gives the watch a strong retro character, while polished dauphine-style hands, a sweep seconds hand, and a practical day-date display at the 3 o’clock position complete the classic Seiko 5 layout.
Powered by the reliable Seiko Caliber 6349 automatic mechanical movement with 21 jewels, this vintage reference combines distinctive case geometry with the mechanical character of classic Japanese watchmaking.
Collector’s Note
The standout feature of this Seiko 5 is its unusual square case design paired with a deep black dial and sparkling crystal-set hour markers. The combination gives the watch a distinctive retro appearance while retaining the practical day-date functionality associated with the Seiko 5 collection.
The solid stainless-steel screw-down case back carries important factory markings, including the 6349-6000 reference, serial number 320162, water-resistance markings, and the vintage Suwa factory symbol.
