Seiko, Ref. 3421-5170, Cal. 3421, Women’s Quartz Analog Vintage Watch, 1980

Vertical brushing on a silver dial contrasts with the horizontally finished bracelet of this Seiko watch from 1980, reference 3421-5170. Two polished baton hands keep the rectangular display simple, with SEIKO QUARTZ beneath 12 and Japan at the lower edge. Quartz caliber 3421 sits inside a 20 mm-wide steel case, with softly rounded edges and an original integrated bracelet.

Brushed silver rectangle and two-hand display

The dial’s fine vertical brushing gives the silver surface subtle movement under light. Applied slim baton hour markers and a minimal printed minute track define the readings. SEIKO QUARTZ appears beneath 12, with a discreet Japan marking along the bottom edge.

Two polished baton-style hands indicate hours and minutes. There is no seconds hand, keeping the display focused on the main time reading. The simple furniture and restrained texture remain central to this early-1980s watch’s dress appearance.

Rounded steel contours and tapered integrated bracelet

The rectangular stainless steel case measures 20 mm across. Softly rounded edges lead into the integrated bracelet, while a polished bezel contrasts with the surrounding brushed surfaces. The slim profile preserves the watch’s compact, jewellery-like presence.

A small fluted crown sits at 3 for time adjustment. Its fine ridges give grip for setting, with a size that remains proportionate to the narrow case.

The original integrated stainless steel bracelet has a horizontal brushed finish and tapers toward its clasp. The difference between the dial’s vertical grain and the attachment’s horizontal finish gives the small watch visual definition, while keeping the metal presentation continuous.
