Seiko Prospex Speedtimer HBJ002P Solar Chronograph Wristwatch

The Seiko Prospex Speedtimer HBJ002P is the standard catalogue companion to the limited-edition HBJ005P — sharing the same Speedtimer architecture, the same Caliber V192 solar chronograph movement, and the same 41.4mm tachymeter-ringed case, now presented in a distinct dial colourway as an ongoing catalogue piece rather than a numbered limited release. The Speedtimer name traces directly to the 1960s and 70s, when Seiko produced some of the most respected chronograph designs in the world for motorsport and aviation applications. The HBJ002P carries that lineage with a tachymeter aluminium bezel, a solar chronograph capable of 1/5 second measurement to 60 minutes, a power reserve display, a 24-hour hand, and a solar cell that eliminates battery replacement. The Caliber V192 runs for approximately 6 months on a full charge. Curved sapphire crystal with inner anti-reflective coating. Stainless steel bracelet with one-push triple fold clasp. Screw caseback. 10ATM water resistance. Anti-magnetic. Core Shop exclusive. Releasing September 2026. Made in Japan. *Pre-Order! Estimated release and shipment from September 2026.* Key Features: Speedtimer Tachymeter Architecture — Motorsport Chronograph Heritage: The aluminium tachymeter bezel display ring, the sub-dial layout with 60-minute chronograph counter, the power reserve display, and the 24-hour hand continue the Speedtimer's 1960s–70s motorsport design language. A watch built for timing, with every element of the dial organised around that purpose. Solar Caliber V192 — 1/5 Second Chronograph, 6-Month Drive: Solar-powered via a cell beneath the dial, the V192 converts any light source into stored energy — approximately 6 months' drive on a full charge, eliminating battery replacement entirely. 1/5 second stopwatch with 60-minute counter, power reserve display, 24-hour hand, date window. ±15 seconds per month accuracy. Curved Sapphire Crystal with Inner AR Coating — 10ATM: The curved sapphire crystal follows the case's profile, with inner anti-reflective coating for clear legibility in any light. 10 bar (100m) water resistance with screw-lock crown and screw caseback. Lumibrite on hands and indices. Anti-magnetic. Stainless Steel Bracelet — Core Shop Exclusive: Stainless steel bracelet with one-push triple fold clasp, maximum 205mm wrist circumference. Available exclusively through Seiko Global Brand Core Shops. 41.4mm x 45.9mm x 13.0mm case, 168g. Made in Japan.
