Seiko Prospex Speedtimer Solar Chronograph Watch

The Seiko Prospex Speedtimer HBJ004 draws inspiration from Seiko’s celebrated sports timing heritage, combining vintage chronograph character with modern solar technology. The 41.4mm stainless steel case features a curved sapphire crystal with an anti-reflective coating, LumiBrite hands and markers, and a tachymeter for classic racing-inspired functionality. Powered by Seiko’s V192 solar movement, the watch offers a 60-minute chronograph measuring in 1/5-second increments, a 24-hour hand, power reserve indicator and date display, with approximately six months of operation when fully charged. A stainless steel bracelet and 100-meter water resistance complete this versatile sport chronograph. Reference HBJ004.
