The Seiko Prospex HBJ001P1 is the plainest reading of the Solar Speedtimer and the one that leaves the chronograph to speak for itself — a silver dial in a 41.4mm stainless steel case on a steel bracelet, with curved sapphire shaped to follow the dial rather than lying flat across it.
What it does is the motorsport brief Speedtimer was built for. A tachymeter on the dial reads speed straight off a timed run, and the stopwatch measures 60 minutes to a fifth of a second with split timing. Calibre V192 supplies the power from light alone, approximately six months from a full charge, with an indicator showing what remains. A date sits on the dial alongside a 24-hour indication, and LumiBrite is applied to the hands and hour markers.

Why You'll Love It
- A silver dial keeps the chronograph registers and the tachymeter scale as the things you notice, which is the point of a timing watch.
- The tachymeter reads average speed directly from a timed run over a known distance, with no setting involved.
- Timing to a fifth of a second across a full hour, and split timing so an intermediate reading does not stop the count.
- Light is the only input. Calibre V192 runs roughly six months from a full charge and shows what is left on a dial indicator.
- LumiBrite on the hands and hour markers, with a date and a 24-hour indication on the dial.
Key Features
- Calibre V192 solar chronograph — drawing power from any light source and holding approximately six months of running when fully charged, with a power reserve indicator on the dial. Seiko Boutique Singapore states its accuracy as ±15 seconds a month over a normal temperature range of 5°C to 60°C.
- Stopwatch measuring 60 minutes in 1/5-second increments — with split time capability for reading an intermediate figure mid-measurement.
- Tachymeter — a fixed dial scale that converts a timed run over a known distance into an average speed.
- Silver dial under curved sapphire crystal — with LumiBrite on the hands and hour markers.
- 41.4mm stainless steel case on a stainless steel bracelet — water resistant to 100 metres, with a pull-out crown.

Frequently Asked Questions
What does the tachymeter do?
It reads speed off a timed run. Start the chronograph at one distance marker, stop it at the next, and the figure the chronograph hand points to on the tachymeter scale is your average speed over that distance. The scale is fixed to the dial, so there is nothing to set or calibrate.
Does it need a battery?
No. Calibre V192 is solar: the dial passes light to a rechargeable cell, which holds approximately six months of running when full. The power reserve indicator on the dial shows the charge level, so normal daily light exposure is all it asks for.
What is split time on the stopwatch?
It lets you take a reading partway through without ending the measurement. The chronograph hand pauses so the figure can be read, then jumps forward to where the count has reached and carries on.
How accurate is it?
Seiko Boutique Singapore states ±15 seconds a month across a normal temperature range of 5°C to 60°C. As a quartz movement that figure applies whether the watch is worn daily or set aside.
Is it safe in water?
It carries a 100-metre rating, which covers swimming and water sports. It is not a diver's watch: the crown pulls out rather than screwing down, and Seiko does not rate it for diving with an air cylinder. The figure is a measured pressure rating rather than a depth to aim for, and neither the crown nor the pushers should be operated while the watch is wet.
Is there a rotating bezel?
No. Seiko lists the rotating bezel as not applicable for this reference, so elapsed time is taken from the chronograph rather than from the bezel.
Can the bracelet be adjusted?
Yes. Links can be added or removed to size the stainless steel bracelet. City Chain offers complimentary bracelet sizing at any outlet — bring your warranty book along for the service.
