Seiko - Precision 19 Seiko 21J Second Setting - 6110-0010 - 1970-1979

This is a Seiko Precision 21 Jewels hand-wound pocket watch, reference 6110-0010, produced in 1973 and powered by the highly regarded Seiko Cal.6110A.

This model belongs to an important lineage in Japanese watchmaking history: the professional pocket watches widely associated in Japan with the famous “19 Seiko” name.

The name “19 Seiko” can sometimes be misunderstood outside Japan. The “19” does not refer to the number of jewels. It comes from the traditional 19-ligne size, approximately 43 mm in movement diameter, used for the large professional pocket watches that became closely associated with Japanese railway timekeeping.

In 1929, Seiko pocket watches of this lineage were adopted by Japan’s Ministry of Railways as official railway watches. For decades, these watches played an important role in supporting the remarkable punctuality and safety of Japanese railway operations, where accurate timekeeping was essential.

The present watch represents a later generation of this tradition.

Inside is the Seiko Cal.6110A, a substantial 21-jewel hand-wound mechanical movement. Compared with the earlier railway pocket watches, this later movement represents the continued development of Seiko’s professional timekeeping instruments, combining robust construction with centre seconds and a practical Second Setting mechanism.

The dial is clearly marked:

SEIKO
PRECISION
21 JEWELS
SECOND SETTING

The Second Setting function is working correctly. When the crown is pulled out, the seconds hand stops, allowing the time to be synchronized precisely.

This is exactly the kind of practical feature that reflects the professional background of the Precision series, where accurate time setting was an essential part of the watch’s purpose.

The serial number 348892 is consistent with production in April 1973.

Another particularly attractive feature of this individual watch is the inscription on the case back:

無事故表彰記念
1973.8.21

This translates approximately as:

“Commemorative Award for an Accident-Free Safety Record – August 21, 1973.”

In Japan, an accident-free award carries a particularly positive meaning. It commemorates safe and conscientious service and can also be appreciated as an auspicious symbol associated with safety, protection and returning home without incident.

This gives the watch a wonderful individual story. A professional-style Precision pocket watch descended from Seiko’s railway timekeeping tradition, presented to commemorate an accident-free record, creates a particularly fitting combination of precision, safety and Japanese history.

The white dial has a beautifully functional appearance, with large black Arabic numerals, bold minute markings, centre seconds and classic hands designed for excellent legibility.

The case measures approximately 50.4 mm in diameter, giving the watch the substantial presence expected from a traditional Japanese professional pocket watch.

The watch is running properly at the time of listing, and the Second Setting function has been tested and is working correctly.

The service history is unknown. Accuracy and power reserve have not been measured.

When winding the watch, no clearly defined hard stop is felt at full winding. The watch winds and is currently running normally, but this point should be taken into consideration.

This watch is offered primarily as a collectible vintage timepiece. It appears suitable for enjoying in its present condition, but if regular everyday use is intended, inspection and servicing by a professional watchmaker are recommended.

Water resistance is not guaranteed. Please keep the watch away from water.

The case and case back show age-related wear, marks and surface deterioration consistent with a vintage professional pocket watch. Please examine all photographs carefully, as they form an important part of the description and show the actual condition of the watch.

For collectors of vintage Seiko, Japanese railway watches and historic mechanical timepieces, this is an especially appealing example.

It combines the heritage of the celebrated 19 Seiko railway-watch tradition, the later 21-jewel Cal.6110A, a functioning Second Setting mechanism, and the wonderfully appropriate 1973 accident-free safety award inscription.

More than simply a vintage pocket watch, it is a fascinating surviving piece of Japanese timekeeping culture — a watch connected with a tradition in which precision and safety truly mattered.

The watch will be carefully packed and shipped from Japan with tracking.
