Featuring a captivating green sunray dial and a robust 41.4mm stainless steel architecture, this timepiece is engineered for watch enthusiasts who demand both high-performance sports functionality and timeless elegance.
Advanced V192 Solar Movement
Powered by Seiko’s innovative Caliber V192 solar movement, the HBJ003P1 harnesses energy from both natural and artificial light sources. Once fully charged, it maintains a dependable power reserve of approximately 6 months, eliminating the need for routine battery replacements. Operating with an accuracy of ±15 seconds per month, it delivers consistent, maintenance-free precision.
Professional Chronograph & Track-Ready Features
Designed with motorsport timing in mind, the vibrant green dial houses a 60-minute stopwatch capable of measuring elapsed time in precise 1/5-second increments. Framed by a tachymeter bezel, it allows wearers to calculate speed with ease. Practical sub-dials—including a 24-hour indicator, small seconds hand, and a dedicated power reserve gauge—are complemented by a discreet date window at an optimal angle.
Exceptional Durability and Comfort
Built to endure daily adventures, the watch is protected by a curved sapphire crystal featuring an anti-reflective coating on the inner surface for maximum clarity under bright sunlight. LumiBrite-coated hands and index markers ensure superior nighttime legibility. With a sturdy 10-bar water resistance, 4,800 A/m magnetic resistance, and a solid 3-link steel bracelet with a secure push-button clasp, the HBJ003P1 weighs 168 grams and offers a secure, comfortable fit.
