Prospex Speedtimer Watch HBD002J1

The Watch

This watch pairs timeless style with a durable build. Part of the Seiko Prospex collection, it combines sophisticated design with advanced functionality. The stainless steel case has a matte, brushed finish that looks refined and stands up to daily wear. Its 42 mm diameter and 14,60 mm thickness give it a noticeable presence on the wrist without feeling overpowering. The bezel, with its tachymeter scale, lets you calculate average speed over a measured distance.

The Dial

The dial of this Seiko Prospex watch features a subtle matte finish and a harmonious mix of gray and blue tones that enhances legibility. Lumibrite-coated hands and hour markers provide a clear reading even in low light. The hour, minute and second hands sweep across a railroad minute track for precise time reading. Three subdials display the 12-hour, 30-minute and 60-second chronograph functions without crowding the dial. A discreet date window completes the design. Protected by domed sapphire crystal with an anti-reflective coating, the dial stays easy to read while the crystal resists scratches and reduces glare.

The Movement

At the heart of this watch is a Seiko 8R48 automatic movement, a fine example of Japanese watchmaking. Known for its precision and durability, the caliber offers a power reserve of 45 hours. Its chronograph function uses the three subdials to time events of up to 12 hours.

The Strap

This Seiko watch has a high-quality leather strap in an elegant gray that complements the dial. The combination creates a refined, timeless look suited to any occasion. With a lug width of 20 mm, the strap offers a comfortable, secure fit for everyday wear. The deployant clasp has a safety closure to help prevent accidental opening.

Water Resistance

With water resistance of 10 ATM (100 meters), this watch is designed to handle splashes, sudden rain and swimming. It offers protection against water and moisture, making it well suited to activities such as sailing and pool swimming. The screw-down case back helps keep water and dust out of the case, protecting the movement inside.
