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.

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.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolar Caliber V192 — 1\/5s Chronograph, Power Reserve Display\u003c\/strong\u003e: Identical to the HBJ001P. 1\/5 second stopwatch to 60 minutes, 24-hour hand, power reserve indicator, date, overcharge prevention.
