| The new Seiko Prospex Speedtimers ditch the chronograph complication entirely. |
Seiko has officially listed all four of its new Prospex Speedtimer mechanicals on its US online store, and the lineup presents watch enthusiasts with an interesting dilemma: sometimes less really is more.
The Japanese watchmaker has priced its HBC003 and HBC004 models at $995 and $950 respectively, while the two HBD chronographs command significantly higher sums at $2,500 and $2,400. But here's the twist—the cheaper pair might just be the more compelling proposition for discerning collectors.
When a Speedtimer Isn't a Chronograph
Here's something you don't see every day: Seiko has built a Speedtimer without a chronograph function. That might sound counterintuitive, but bear with us.

The HBC003 and HBC004 feature a second crown positioned at 4 o'clock that operates an inner ring carrying a countdown scale. Rather than pressing a pusher to start and stop a timing mechanism, you simply rotate that inner ring by hand and line it up against whatever interval you're tracking. Nothing starts. Nothing stops. The hands sweep past a number you've set yourself.
This approach mirrors how drivers and navigators kept time before affordable stopwatches became ubiquitous. It's a nod to practical, analog timekeeping that predates the chronograph craze. Perhaps more importantly, it keeps the dial remarkably clean—something a traditional sub-register layout simply cannot achieve.
Impressive Specifications at an Accessible Price
Despite the lower price point, the HBC models don't skimp on substance. Both are powered by Seiko's 6R55 caliber, operating at 21,600 vibrations per hour with an impressive 72-hour power reserve. That's three full days of autonomy when you set the watch down on Friday evening.
The steel case measures a versatile 39.5mm across, 12mm thick, and 44.5mm lug to lug—dimensions that should sit comfortably on a wide range of wrists. Water resistance is rated at a capable 200 meters, making these perfectly suitable for swimming and recreational diving.
Curved sapphire crystal protects the dial, enhanced with an anti-reflective coating on the inner face for improved legibility in challenging lighting conditions. LumiBrite covers both the hands and indexes, ensuring visibility in low-light situations.
Two Distinct Personalities
The HBC003 and HBC004 offer buyers a choice between two very different aesthetic directions.
The HBC003 ($995) features a light blue vertically brushed dial paired with orange accents on the chapter ring and seconds hand, mounted on a matching bracelet. It's a sporty, contemporary look that feels right at home in the Prospex lineup.
The HBC004 ($950) takes a different approach with a dark grey dial and embossed cow leather strap. According to Seiko, the design is meant to evoke the interior of a classic car—a fitting tribute for a watch inspired by vintage motorsport timing.
The Higher-Priced Chronographs Make Their Case
For buyers willing to spend more than double, the HBD001 and HBD002 offer traditional chronograph functionality with some trade-offs.
The HBD001 measures 42mm × 14.6mm × 49.5mm and drops to 100 meters of water resistance—a notable step down from the HBC models. Its 8R48 column-wheel chronograph movement delivers only 45 hours of power reserve, a full day less than the cheaper watches.
What the HBD models do offer is enhanced magnetic resistance at 4,800 A/m, meeting the exact ISO 764 threshold. They also include a tachymeter scale along with 30-minute and 12-hour registers for comprehensive timing capabilities.
The Value Proposition
American buyers appear to be getting a favorable deal compared to their UK counterparts. Seiko UK lists the HBC003 at £870, which initially looks like a significant premium over the $995 US price. However, once you account for VAT differences, most of that gap disappears—a reminder that international price comparisons require careful analysis beyond simple currency conversion.
For collectors seeking something genuinely different from the typical chronograph offerings flooding the market, the HBC003 and HBC004 present a compelling case. They're mechanical, well-specified, attractively priced, and offer a user experience that's refreshingly analog in an increasingly digital world.
Sometimes the most interesting watches aren't the most expensive ones—they're the ones that make you think differently about what a watch can be.
