Seiko Expands Speedtimer Line with Four New Mechanical References

Seiko has added four new mechanical watches to its Prospex Speedtimer collection, comprising two chronographs and two time-and-date models. The new references feature lighter dial colors, including sky blue and silver grey, alongside updated case designs. The chronographs are powered by the 8R48 movement, while the time-and-date models use the 6R55. These additions are part of Seiko's 145th anniversary celebrations and are available immediately.
Key points
- Seiko released four new Speedtimer references: HBD001, HBD002, HBC003, and HBC004.
- The HBD001 and HBD002 are mechanical chronographs with 42mm cases and the 8R48 movement.
- The HBC003 and HBC004 are time-and-date models with 39.5mm cases and the 6R55 movement.
- New dial colors include sky blue, silver grey, and light blue with vertical engraved lines.
- Prices range from EUR 1,000 to EUR 2,780, with the chronographs priced higher than the time-and-date models.
Background
The Speedtimer name has historical significance for Seiko, originating from the 1969 launch of the brand's first automatic chronograph. In recent years, the collection has expanded beyond chronographs to include time-and-date models. In August 2026, Seiko marked its 145th anniversary with a limited-edition solar Speedtimer featuring an Edo purple dial. The current release expands the mechanical lineup with new colorways and case designs.
How outlets are covering it
Monochrome Watches emphasizes the retro-styled design of the new chronographs, noting the 'helmet-like' center section inspired by 1970s models. Fratello Watches highlights the detailed dial designs and the comfort of the new bracelets, while also noting a preference for the bracelet over the leather strap for the HBD002. Oracle Time focuses on the practical applications of the countdown bezel on the time-and-date models and compares the chronograph prices to other brands like TAG Heuer and Breitling. All sources agree on the technical specifications and pricing, but differ in their emphasis on design aesthetics and market positioning.
Why it matters
The expansion of the Speedtimer collection with new mechanical references and lighter dial colors broadens Seiko's appeal to collectors and enthusiasts seeking motorsport-inspired watches. The introduction of new colorways and case designs adds variety to the lineup, while the use of in-house movements like the 8R48 and 6R55 reinforces Seiko's commitment to mechanical craftsmanship. The pricing positions these watches competitively within the mid-range market, offering alternatives to luxury chronographs.
What to watch
The four new Speedtimer references are available immediately as part of Seiko's permanent collection. Oracle Time also noted that three previous Solar Speedtimer models are receiving SKU refreshes, including a new Racing Green edition, all priced at £670. These updates may affect availability and pricing for existing models, potentially impacting collectors and buyers.
