Seiko Prospex SPEEDTIMER SBER003 – Solar Chronograph 1/100 Second Power

For those who move faster than time itself.

The Seiko Prospex SPEEDTIMER SBER003 (SFJ003) is a high-precision solar chronograph that delivers timing accuracy down to 1/100th of a second — ideal for sports timing, training, or motorsport fans.

Powered by Seiko’s Caliber 8A50, it combines solar efficiency with cutting-edge stopwatch functionality.

Its curved sapphire glass with internal anti-reflective coating ensures crystal-clear legibility, while LumiBrite on hands and indexes means night-time readability.

Crafted in stainless steel, the watch is robust yet wearable, with 100M water resistance and a screw-down caseback for added security.

With a 60-minute chronograph, battery level indicator, and needle auto-correction, it’s as smart as it is sporty.

The SBER003 is built for speed, precision and endurance.

 If you need a reliable tool for exact timing and a bold, sporty aesthetic, this solar chronograph is the perfect blend of style and performance.
