Seiko - Open-Face Quartz Large Arabic Dial - 7550-0010 - 1980-1989

Introduction

A Seiko Quartz open-face pocket watch powered by the Seiko calibre 7550, presented in a large chrome-finished round case with a polished bow and crown. The white dial carries bold Arabic numerals and a long sweep seconds hand at centre, with 'SEIKO QUARTZ' printed below 12 o'clock and the Seiko logo mark at the lower centre. The caseback is stamped with reference 7550-0010 ACRP, confirming a white base-metal plating finish, made in Japan.

Historical / Era context

ACRP on the caseback is a white base-metal plating designation used on Japanese-market Seiko pocket watch cases of this era. With its large, highly legible Arabic numeral dial and sturdy round case, this piece represents Seiko's reliable quartz pocket watch line aimed at practical, everyday use.

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 case retains its overall round form and the bow and crown are intact. The exterior caseback shows significant plating loss across much of its surface, with mottled bare metal visible beneath. The bezel and mid-band show scattered fine scratches consistent with age and use.

Dial: The white dial is clean and legible, with all Arabic numerals and printed text reading sharply. No staining, fading, or damage is visible on the dial surface.

Crystal: The crystal is clear and free of cracks. Light surface scratches are present but do not obstruct dial reading.

Movement: The watch is running. With the caseback opened, the Seiko Quartz movement is visible, signed 'SEIKO QUARTZ JAPAN' on the movement plate with 'FIVE 5 JEWELS' indicated. The movement is clean with no obvious damage to the components.

Accessories: No box, papers, or chain/fob are included. The watch is offered as shown.

Please review all photographs carefully for the detailed condition.
