Speedtimer is Seiko's motorsport timing line, and the Seiko Prospex HBJ002P1 puts it behind a champagne gold dial — a warmer reading of a format usually kept monochrome. The 41.4mm case and bracelet are stainless steel, and curved sapphire sits over the dial rather than a flat crystal.
The timing hardware is the point. A tachymeter converts an elapsed time into a speed, and the stopwatch runs to 60 minutes in 1/5-second steps with split timing for intermediate readings. Power comes from calibre V192, which charges from any light source and holds approximately six months on a full charge, with an indicator on the dial showing what is left. There is a date, a 24-hour indicator, and LumiBrite on the hands and hour markers.

Why You'll Love It
- Champagne gold is the warm option in a line that usually runs black, white or green, and the curved sapphire follows the dial rather than sitting flat across it.
- A tachymeter on the dial, which is what turns the chronograph from a stopwatch into a speed reading.
- Timing to a fifth of a second across a full hour, with split timing so an intermediate reading does not end the measurement.
- No battery to replace. Calibre V192 charges from any light source and runs about six months from full, and the dial indicator tells you where the charge stands.
- LumiBrite on the hands and hour markers, and a date at a glance.
Key Features
- Tachymeter scale — a fixed scale on the dial that reads average speed directly from a timed run over a known distance, with nothing to set.
- 60-minute stopwatch in 1/5-second increments — with split timing, so an intermediate figure can be read off while the measurement carries on underneath it.
- Calibre V192, solar — charged by any light source, holding approximately six months of running when full. Seiko Boutique Singapore gives its accuracy as ±15 seconds a month over a normal temperature range of 5°C to 60°C.
- Champagne gold dial behind curved sapphire — with LumiBrite applied to the hands and hour markers.
- Power reserve indicator, date and 24-hour indication — reading alongside the hour, minute and seconds hands.

Frequently Asked Questions
How do I read the tachymeter?
Start the chronograph at a known distance marker and stop it at the next one. Where the chronograph hand lands on the tachymeter scale is your average speed over that distance — kilometres per hour if you measured a kilometre, miles per hour if you measured a mile. It is a fixed scale, so it needs no setting.
What is the 24-hour indicator for?
It shows the time on a 24-hour cycle alongside the normal hands, so morning and evening are distinguishable at a glance. Seiko lists the hand indicators for this reference as hour, minute, seconds and 24-hour.
How does a solar watch work in practice?
The dial passes light to a rechargeable cell, so there is no battery to replace on a service schedule. A full charge runs the watch for approximately six months, and the power reserve indicator on the dial shows how much is left rather than leaving you to find out when it stops. Normal indoor and daylight exposure keeps it topped up.
How accurate is it?
Seiko Boutique Singapore states ±15 seconds a month across a normal temperature range of 5°C to 60°C. Being quartz, that holds whether the watch is worn daily or left in a drawer.
Can I wear it in water?
It is rated to 100 metres, 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 rating is measured pressure, not a depth you are invited to reach, and the crown and pushers should not be operated while the watch is wet.
Does the bezel rotate?
No. Seiko lists the rotating bezel as not applicable for this reference, so elapsed time is read from the chronograph rather than by turning the bezel.
Can the bracelet be sized?
Yes. Links can be added or removed to fit the stainless steel bracelet to your wrist. City Chain offers complimentary bracelet sizing at any outlet — bring your warranty book along for the service.
