Seiko - Open-Face Stainless Quartz - 7N01-0020 - 1990-1999

Introduction

This is a Seiko open-face pocket watch powered by a quartz movement, presented on a stainless steel curb chain with a belt clip fob. The clean white dial carries bold Arabic numerals and two slim baton hands, with the SEIKO name printed just above centre — a simple, legible layout designed for everyday use. The caseback is stamped SEIKO / STAINLESS STEEL / 7N01 0020 B0, confirming a stainless steel case housing Seiko's 7N01 quartz caliber.

Historical / Era context

The 7N01 caliber is one of Seiko's long-running two-hand quartz pocket watch movements, produced in Japan and used across several generations of the company's open-face carry watch line. With its stainless steel case, minimalist sunburst-centre dial and swivel-ring bow, this piece sits squarely in Seiko's tradition of producing reliable, no-frills pocket watches for daily use. The accompanying chain and belt-clip fob are third-party accessories rather than original Seiko issue, as noted below.

Condition

The watch is running and keeping good time. The watch was checked running at the time of listing with a fresh battery. Battery life and long-term accuracy are not guaranteed. As a vintage timepiece it may benefit from a service.

Case: The polished stainless steel case retains a good overall shape. Light scattered surface scratches are present on the caseback, consistent with normal handling. The bezel rim and band show minor scuffs but no dents or deformation.

Dial: The white dial is clean and legible with no staining, spotting or damage visible. Printing is crisp and the minute track is intact.

Crystal: The mineral crystal is clear with no cracks. Fine light surface marks are present but they do not impede legibility.

Movement: The watch is running. With the caseback opened, the compact Japanese-made 7N01 quartz module is visible, mounted in a green rubber movement ring on a white dial plate. The battery (SR621SW type visible on the cell) is installed and the watch is keeping time.

Accessories: Supplied with a third-party stainless steel curb chain with a spring-clip fitting and a belt-clip fob bar marked STAINLESS STEEL-B. No original box or papers.

Please review all photographs carefully for the detailed condition.
