October 1974 | Automatic | 23 Jewels | Blue Dial | Brown Leather Strap
A vintage Seiko with a beautiful blue dial that changes character with the light.
Manufactured in October 1974, this Seiko 5 Actus 6106-8660 represents the distinctive design and craftsmanship of Seiko's 1970s automatic watches.
Its most striking feature is the richly colored blue dial.
Under bright light, the dial reveals a vivid cobalt blue. From different angles or in softer indoor lighting, it takes on a deeper navy tone.
The simple baton hour markers and slender hands complement the dial without overwhelming its beauty.
Paired with a brown leather strap, this watch offers a warm, classic appearance that works equally well with casual clothing or a jacket.
The blue dial is beautifully preserved, retaining its vivid color and attractive finish.
The hands and hour markers show no significant visible deterioration.
The rounded stainless steel case features the characteristic proportions of 1970s Seiko design.
Minor scratches and signs of previous use are present, consistent with its age. The original case lines and lugs remain well defined, with no major dents observed.
The original crystal has been replaced with a new crystal by StoryWatch.
This provides clear visibility and allows the beautiful blue dial to be appreciated without distracting surface wear.
This watch is powered by a Seiko Caliber 6106 automatic movement with 23 jewels.
The movement has undergone a basic service by StoryWatch, including inspection and rate adjustment.
The watch has been checked and is currently running.

At StoryWatch, we believe that restoring a vintage watch is not about making it completely new.
Our goal is to preserve the character developed over decades while carefully preparing each watch for its next chapter.
The movement has been inspected and adjusted, and a new crystal has been installed to restore the clarity of the dial.
Inside the case back, we have placed a StoryWatch service-date stamp as a record of the work performed.
This small detail documents the watch's journey through our workshop.
Manufactured in October 1974, this Seiko has been part of history for more than half a century.
For someone born in 1974, it may be a meaningful birth-year watch.
For another collector, it may simply be a beautiful example of vintage Japanese watchmaking.
