Seiko - Precision Second Setting Open Face Pocket Watch - 6110-0010 - 1970-1979

Introduction

This is a Seiko Precision open-face pocket watch with a bold white dial carrying large black Arabic numerals, blued sword hands, and a subsidiary seconds hand at the 6 o'clock position. The dial is signed 'SEIKO PRECISION 21 JEWELS' and carries the text 'SECOND SETTING', indicating a keyless second-setting mechanism for precise time synchronisation. The movement is a hand-wound caliber 6110A, 21 jewels, made in Japan.

Historical / Era context

The Seiko Precision open-face pocket watch belongs to a long lineage of high-grade Japanese pocket watches developed by Seiko (formerly Seikosha) from the Meiji era onward. The 6110A caliber is a robust 21-jewel hand-wound movement, and the open-face format with large Arabic numerals was well suited to quick, legible reading. The case reference 6110-0010 stamped on the caseback identifies this as a standard production variant of this caliber family.

Condition

The watch is running and keeping good time. The watch was checked lying flat (dial up) after a full wind. This is a spot check at the time of listing; as a vintage mechanical watch the rate in actual wear varies with position and winding state, and long-term accuracy is not guaranteed. As a vintage timepiece it may benefit from a service.

Case: The case carries the ACRP stamp, a white base-metal plating mark. The exterior surfaces show heavy scattered pitting and spot corrosion across the caseback, and the bezel rim shows wear with loss of surface finish in multiple places. The mid-band also has scattered blemishes consistent with age and use. The crown and bow ring remain present and functional.

Dial: The white dial is clean and legible, with all numerals and text crisp and well-preserved. I can see no staining, cracking, or significant discolouration on the dial surface.

Crystal: The crystal has a crack. This is visible in the dial photos and should be noted carefully by prospective buyers.

Movement: The watch is running. With the caseback opened, the movement is visible: caliber 6110A, 21 jewels, signed SEIKO JAPAN, with a nicely finished gilded mainplate, ruby jewels, and a free-sprung balance. The movement is in good working order.

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

Please review all photographs carefully for the detailed condition.
