Seiko – Speedtimer Solar Chronograph Limited Edition Black Case – SFJ007
Sports timing tradition inspires a new solar-powered calibre

Limited Edition of 4000 Pieces

On the eve of the 2023 World Athletics Championships
in Budapest, Hungary, Seiko is rolling out a new
sports-timing calibre in its latest Solar Speedtimer.

Called Calibre 8A50, this 1/100th of a second
chronograph is capable of timing multiple sporting
events (ie: multiple lap times) with incredible
precision and accuracy.

In keeping with Seiko’s rich history of timing sporting
events, this distinctive Speedtimer is built around four
timekeeping displays (two 1/100 totalizers at 3H and 9H,
and a 60 second totalizer at 12H), a tribute of sorts to
Seiko’s vintage Sportura models.

Like the rest of Seiko’s Solar-powered movements,
this Speedtimer can run autonomously for approximately
six months when fully charged, and maintains an accuracy
rating of ±15 seconds per month.
