Experience Precision and Heritage: Seiko's Latest Speedtimer Collection Unleashed!

Unveiling the Prospex Speedtimer Mechanical Chronographs: HBD001 & HBD002

The latest additions to the mechanical chronograph lineup, the HBD001 and HBD002 models, draw inspiration from the iconic Speedtimer chronographs of the early 1970s. These pieces feature a redesigned, more aesthetically pleasing case measuring 42mm in diameter and 14.6mm in thickness, crafted from hard-coated steel with a meticulous blend of brushed and polished finishes. A striking "helmet-like" central section pays homage to vintage models, while a sapphire crystal protects the dial. The robust, engraved solid steel caseback, in a departure from transparent designs, enhances its vintage appeal and ensures a practical 100m water resistance, a notable feature for a chronograph.

Dial Dynamics and Aesthetic Distinctions of the Chronograph Models

For 2026, the dials of the HBD001 and HBD002 introduce an intriguing element: vertical engraved lines on their base. The HBD001 showcases a vibrant sky blue background complemented by contrasting black elements for the tachymeter scale and chronograph sub-dials at 6 and 9 o'clock, ensuring clear readability. The small seconds counter at 3 o'clock is subtly lighter, blending seamlessly with the main dial, accented by a crisp white seconds track. In contrast, the HBD002 offers a more refined palette with a warm silver tone for its base, set against sky blue chronograph counters, and is presented on a grey leather strap. The HBD001, meanwhile, is paired with a hard-coated steel bracelet.

The Heart of the Chronographs: Calibre 8R48 Movement

Both HBD001 and HBD002 models are powered by the sophisticated Calibre 8R48, an automatic movement celebrated for its vertical clutch and column wheel mechanisms. This combination guarantees an exceptionally smooth operation of the chronograph functions and precise hand actuation. Beating at a frequency of 4Hz, the movement benefits from MEMS technology, which contributes to a lighter and more resilient escapement. These exquisite chronographs are slated to join the permanent collection, with the HBD001 priced at EUR 2,780 and the HBD002 at EUR 2,680.

Introducing the Prospex Speedtimer Mechanical HBC003 & HBC004 (Time-and-Date)

Beyond the chronographs, the Speedtimer collection welcomes two new time-and-date models, the HBC003 and HBC004, designed for everyday versatility. Building on the success of previous time-and-date Speedtimer releases, these watches maintain a strong motorsport aesthetic without chronograph functionality. They boast ideal proportions with a 39.5mm diameter and 12.0mm thickness, complemented by an internal rotating bezel that enhances their sporty appeal. A sapphire crystal protects the dial, and a solid steel back ensures an impressive 200m water resistance, making them robust companions for daily wear.

Design and Movement of the Time-and-Date Models

The HBC004 model introduces a leather strap variant, sharing its dark grey (almost black) dial and vibrant orange accents on the inner flange with the bracelet-equipped SPB515. The HBC003, on the other hand, features an eye-catching light blue vertically brushed dial, also with orange accents, and comes paired with a stainless steel bracelet. Both timepieces are equipped with the dependable Calibre 6R55, an in-house automatic movement offering a substantial 72-hour power reserve. With a frequency of 21,600 vibrations/hour and a magnetic resistance of 4,800 A/m, these watches are engineered for durability and precision in various conditions. The HBC003 is priced at EUR 1,030, and the HBC004 at EUR 1,000, both becoming permanent fixtures in the collection.
