Seiko Quartz Railwayman's Pocket Watch (1985) – Ref. 7550-0010

Rare and historically significant Seiko Railway Pocket Watch (鉄道時計), made for the Japan National Railways (国鉄 – Kokutetsu).
This example dates from 1985 and was manufactured for use by railway staff of the Okayama Railway Division (岡鉄).
It is one of the last official service watches of the Japanese State Railways before its privatization (1987) and was issued exclusively to train drivers and conductors.

Historical background

The following is engraved on the back of the case:
昭60 (Shōwa 60) = 1985
This clearly places this watch in the late JNR era, just two years before the dissolution of Japan National Railways.

The engraving岡鉄stands for “Okayama Tetsudō” – the Okayama Railway Division in western Japan.
Such service engravings were found exclusively on officially issued Seiko railway watches, which were produced according to precise specifications for railway personnel.

These pocket watches were subject to strict accuracy regulations and were regularly checked and adjusted by Seiko.
