Vintage Seiko UFO Chronograph

Description

Vintage Seiko UFO Chronograph “Big Eye Small Eye” | Cal 6138 | Automatic | Day/Date | 1970s

A bold and iconic vintage Seiko automatic chronograph from the 1970s, affectionately nicknamed the “UFO” for its distinctive flying-saucer-shaped case, and the “Big Eye, Small Eye” for its asymmetrically sized subdials — one of Seiko’s most beloved vintage chronograph designs. Powered by the legendary Caliber 6138 automatic movement running at 21,600 BPH, with day/date complication for everyday practicality. The deep black dial with contrasting silvered subdials delivers striking visual punch, complemented by long sword hands, a vivid orange central chronograph seconds hand, and a black tachymeter bezel on the polished case. A genuinely sporty and unmistakably 1970s Seiko, highly sought after by chronograph collectors and vintage Japanese watch enthusiasts alike.
