Seiko Prospex Speedtimer Automatic – HBD001

The Seiko Prospex Speedtimer brings the spirit of Grand Touring to the wrist, inspired by the pleasure of driving, innovative technology, and unforgettable journeys. Its striking light blue dial features three dark gray subdials, creating a sophisticated contrast and excellent legibility, while sky blue accents on the central seconds hand and chronograph counters reinforce its distinctive instrumental character. The 42mm stainless steel case, finished with a super-hard coating, reinterprets Seiko’s legendary 1972 “Panda” chronograph with flowing lines and finely crafted details that blend classic motorsport inspiration with contemporary design. Powering the Speedtimer is Seiko’s automatic Caliber 8R48, which also supports manual winding and provides approximately 45 hours of power reserve. The mechanical chronograph measures intervals of up to 30 minutes and 12 hours, while a date display and stop-seconds function add everyday practicality. A double-domed sapphire crystal with internal anti-reflective coating protects the dial, while LumiBrite on the hands and indexes enhances visibility in low-light conditions. Measuring 14.6mm thick and 49.5mm from lug to lug, the watch makes a confident statement on the wrist and is complemented by a multi-row stainless steel bracelet with a safety folding clasp. With 100 meters of water resistance, the Seiko Prospex Speedtimer HBD001J1 offers a compelling combination of motorsport heritage, mechanical performance, and refined contemporary style.
