Story & heritage
Seiko USA says this limited edition is inspired by Seiko’s—and the world’s—first analog quartz chronograph, which featured a 1/100-second stopwatch.
The official listing notes a 4,000-piece edition commemorating the World Athletics Championships Budapest 23, for which Seiko was official timer.
Materials & craft
The official specification lists the solar chronograph 8A50 movement with 1/100-second stopwatch timing, measurement up to 60 minutes, and split-time function.
It is powered by light energy, needs no battery change, and has a six-month power reserve once fully charged.
How to choose & style
Treat it as the graphic statement chronograph in the Seiko lineup; the dial density is the point.
Keep the rest of the outfit quiet so the subdials, indices, and timing scale read intentional rather than busy.
