One of the most exciting and popular Seiko releases of the past few years has been the brand’s solar-powered Speedtimer line of chronographs.
First introduced in the fall of 2021, the Prospex Solar Speedtimer instantly became a fan-favorite for its combination of a wearable 39mm case size, a laundry list of specs including a sapphire crystal, Lumibrite lume and 100m of water resistance, and a Rolex Daytona-adjacent design, all for an ultra-competitive sub-$1,000 price tag.
One reference in particular has become something of a modern classic. The reference SSC813 has been given the nickname “Seitona” due to its resemblance to the modern Rolex Daytona “Panda,” a result of the watch’s stark-white dial, thick black tachymeter bezel and black subdials.
Now, the “Seitona” has some competition in Seiko’s Solar Speedtimer lineup, as the Japanese brand has debuted a new version of the chronograph that looks a whole lot like a vintage Rolex Daytona Panda.

Seiko’s new chronograph is the Prospex Speedtimer ‘Motoring,’ and while it’s largely the same watch as the SSC813 “Seitona” and other Solar Speedtimers, it has some unique touches, too.
First, let’s talk about the design. Like the “Seitona,” it has a panda dial, but it’s a decidedly more retro one. Instead of going with contemporary, optic white for the dial like the SSC813, the ‘Motoring’ opts for a cream-colored dial that gives the watch an aged look. The chronograph registers remain black, and the date wheel is now black as well, adding a bit more character to the dial.
