SEIKO Prospex SPB411 Special
A faithful re-creation of an archival model from 1968
For its latest watch, Seiko Prospex has re-created the model from 1968 that was Seiko’s first GMT to feature a rotating bezel. The new limited edition is as faithful as possible to the classic sports design and compact dimensions that characterized the late-‘60s Navigator Timer. A distinctive five-row bracelet glitters to complete the watch’s classic and luxurious look.
On the dial, the Seiko logo follows the design of the original model and is lower in height than the current logo. The GMT, hour, and minute hands, as well as the indexes, also follow the Navigator Timer design. With its independently adjustable GMT hand and 24-hour rotating bezel, this handsome traveler’s watch displays the time in three places at once.
The case back bears a horseshoe-shaped design similar to the original model and displays the individual watch’s serial number.
＊ In the actual product, the case back direction might be different from that of the photograph.

The first watches produced under the Seiko brand appeared in 1924. In 1969, Seiko introduced the Astron, the world’s first production quartz watch, it cost the same as a medium-sized car. Seiko later went on to introduce the first quartz chronograph.
