Description
The SEIKO Prospex Speedtimer SFJ007 is a bold and innovative chronograph built to commemorate the World Athletics Championships Budapest 2023. Limited to 4,000 pieces worldwide, this solar-powered timepiece is capable of measuring elapsed time with remarkable 1/100th-second precision—making it one of Seiko’s most accurate analog chronographs to date. The 42mm stainless steel case is coated in black hard coating for a stealthy aesthetic and enhanced durability. A uniquely textured black dial mimics the lanes of a running track, complemented by gold-tone chronograph hands for high visibility. Powered by the Seiko Caliber 8A50, the watch offers a 6-month power reserve on a full solar charge. With four distinct subdials for multi-function timing, a curved sapphire crystal, and 100 meters of water resistance, the SFJ007 combines technical prowess with limited-edition appeal.
