A beautifully restrained vintage Seiko Chariot Quartz reference 4720-3020, combining a slim rectangular stainless-steel case with a vertically brushed silver dial and minimalist baton markers.
This is a particularly appealing example of Seiko's late-1970s approach to quartz dress watches: compact, architectural and exceptionally clean in design. The caseback clearly carries the 4720-3020 reference, while Japanese market records identify this reference with the Chariot line and confirm the quartz configuration.

A documented example of reference 4720-3020 measures approximately 20 × 27mm, while Japanese auction records specifically describe the model as a 1970s rectangular Seiko quartz watch.
Condition
The watch presents with an attractive, honest vintage appearance.
The silver dial remains especially appealing, with its vertically brushed finish creating subtle changes in tone under different lighting. The applied baton markers and printed SEIKO QUARTZ signature remain clear and well defined. Some light age-related marks and imperfections are visible, as expected from a vintage watch.
The stainless-steel rectangular case shows surface scratches, hairlines and general signs of previous wear. The case retains its strong angular profile and the stepped geometry that gives this reference much of its character.
The caseback is similarly marked from use but remains highly legible, including the important 4720-3020 reference and serial number.
The black leather-style strap appears to be a later replacement rather than something that should automatically be considered original Seiko equipment. It presents well and complements the silver dial nicely.
No claim is made regarding recent servicing, battery age or long-term timekeeping accuracy unless separately confirmed. Given the age of the watch, water resistance should not be assumed.
Please study all photographs carefully, as they form an important part of the condition description.
The Chariot Connection
The Chariot name occupies an interesting place within vintage Seiko dress watches. Rather than the overtly sporty styling associated with many Seiko models, Chariot pieces generally pursued a cleaner, more formal aesthetic.
Japanese marketplace records specifically catalogue the 4720-3020 as a Seiko Chariot quartz reference, while surviving examples appear in both silver and gold-toned dial configurations.
The result is a watch that feels very much of its period without becoming visually excessive.
Early Quartz-Era Seiko Character
The 1970s were a transformative period for Seiko, with quartz technology moving rapidly from technological showcase to a practical alternative to mechanical watchmaking.
Reference 4720-3020 reflects the design language that accompanied that transition. Instead of making the technology itself visually dominant, Seiko packaged quartz precision inside a traditional dress-watch format: a slim rectangular case, simple dial, two hands and almost no unnecessary decoration.
Japanese auction records describe surviving 4720-3020 examples specifically as 1970s quartz watches.
A Classic Rectangular Dress Watch
The proportions are a major part of this watch's appeal.
At approximately 20 × 27mm, comparable examples have genuinely traditional vintage dimensions. The rectangular case, sharply defined shoulders and narrow dial create the elongated appearance associated with classic tank-style watches.
The silver-on-silver presentation makes this example particularly versatile, while the black strap provides a strong visual contrast.
Why Collectors Love the Seiko 4720-3020
The attraction here is simplicity.
There is no date window, oversized branding or unnecessary complication. Instead, the design relies on proportion, texture and geometry: a brushed silver dial, polished baton markers, slim hands and a sharply defined rectangular stainless-steel case.
Add the clearly identifiable 4720-3020 reference, period quartz movement and Chariot association, and this becomes an interesting piece of Seiko's 1970s design history rather than simply another vintage quartz watch.
