Import duties and customs fees are not included and will be collected by the carrier upon delivery, except for shipments to the USA where these fees are included at checkout.
The Seiko Prospex Speedtimer Solar Chronograph HBJ004P is the black-dialled companion to the HBJ001P — the same Caliber V192 solar chronograph platform, the same tachymeter bezel, the same curved sapphire crystal with inner anti-reflective coating, the same power reserve display, the same Core Shop exclusive distribution. The difference is the dial: where the HBJ001P wears blue and silver, the HBJ004P goes black and green — a darker, more assertive expression of the Speedtimer's motorsport identity, closer in character to the instruments of endurance racing than to the open-road touring aesthetic of the blue model. The black dial maximises contrast against the green accents and the luminous Lumibrite treatment on hands and indices, making the HBJ004P the stronger legibility choice in bright light. Solar Caliber V192, 1/5 second stopwatch to 60 minutes, 24-hour hand, power reserve display, date. Stainless steel case with Dia-Shield coating, 41.4mm diameter, 168g. Core Shop exclusive, releasing September 2026.
Key Features:
- Black Dial — Endurance Racing Instrument Aesthetic: The black dial places the HBJ004P at the darker end of the Speedtimer palette — closer to the instrument panels of endurance racing machines than to open-road GT cars. Green accents provide the contrast, matching the tachymeter scale's character. A dial optimised for legibility in direct sunlight, where a black background against luminous hands is faster to read than any lighter alternative.
- Solar Caliber V192 — 1/5s Chronograph, Power Reserve Display: Identical to the HBJ001P. 1/5 second stopwatch to 60 minutes, 24-hour hand, power reserve indicator, date, overcharge prevention. Solar-powered with approximately 6 months' drive on a full charge.
- Tachymeter Aluminium Bezel — Same Motorsport Tool Function: The tachymeter scale is the same as the HBJ001P — a genuine speed calculation tool carried from the original Speedtimer lineage unchanged. Start at a distance marker, stop at the next, read average speed directly from the bezel.
- Curved Sapphire with Inner AR — Dia-Shield Case, 168g: Stainless steel case with Dia-Shield coating, 41.4mm x 45.9mm x 13.0mm, 168g. Curved sapphire crystal with inner anti-reflective coating. Lumibrite on hands and indices. Screw caseback. One-push triple fold, max 205mm wrist. Core Shop exclusive.
