The Seiko Prospex HBJ005P1 is a limited edition chronograph created to celebrate the 145th anniversary of Seiko, honouring the brand's beginnings as a Tokyo clock and watch repair shop in 1881. Inspired by the legendary Seiko Speedtimer first introduced in 1969, this commemorative model pays tribute to one of Seiko's most significant milestones in chronograph innovation. Its striking Edo Murasaki (Edo Purple) dial reflects a traditional Japanese colour that symbolises hope for the future and the refined beauty of Tokyo's historic Edo period, giving the HBJ005P1 a distinctive and sophisticated character.
Designed with heritage-inspired details, the HBJ005P1 features a bi-colour black and purple aluminium bezel that frames the dial with bold contrast. The hour and minute hands are styled after the original 1969 Speedtimer, while 12 Lumibrite markers provide excellent visibility in darker conditions. A chronograph second scale surrounds the dial, and the iconic tachymeter bezel allows speed measurement, preserving the unmistakable design elements that made the original Speedtimer a classic.
Powering the Seiko Prospex HBJ005P1 is the in-house V192 solar-powered quartz chronograph movement, delivering impressive accuracy of ±15 seconds per month with the convenience of eco-friendly charging from both natural and artificial light. Once fully charged, the movement provides a six-month power reserve, offering dependable everyday performance. As part of the renowned Prospex collection—combining "Professional" and "Specifications"—the HBJ005P1 is built to deliver the reliability, durability and precision expected by sports enthusiasts, collectors and fans of Seiko's iconic chronograph heritage.
