Seiko Prospex Speedtimer HBJ003 Men's Green Solar Chronograph Watch

Overview

The Seiko Prospex Speedtimer HBJ003 brings classic motorsport style to a modern solar chronograph. Its rich green dial, contrasting black subdials and black-and-green aluminum tachymeter bezel create a distinctive racing-inspired look, balanced by a stainless steel case and matching bracelet. Its hands echo the original 1969 Speedtimer. The LumiBrite hands and hour markers provide clear visibility in low light, while a discreet date window adds everyday convenience. Powered by Seiko's V192 solar movement, the watch converts light into energy and runs for approximately 6 months when fully charged. With an accuracy of +/-15 seconds per month, it offers reliable timekeeping without manual winding. The chronograph measures elapsed time up to 60 minutes in 1/5-second increments, complemented by a 24-hour display, small seconds and a power reserve indicator. An overcharge prevention function helps manage charging. Measuring 41.4mm across, 13.0mm thick and 45.9mm from lug to lug, the case gives the watch a sporty presence with proportions suited to daily wear. A curved sapphire crystal with an anti-reflective coating on its inner surface protects the dial and reduces distracting reflections. The stainless steel bracelet secures with a three-fold clasp and push-button release. Water resistance to 100 meters, a screw case back and magnetic resistance of 4,800 A/m add practical durability. Inspired by Seiko's chronograph heritage and the character of classic racing cars, the HBJ003 pairs bold green color with useful timing functions. From weekday outfits to relaxed weekends, it delivers a confident blend of vintage character, modern technology and versatile steel styling.

Gold Jewelry
Keep your gold pieces looking their best by cleaning them regularly with a soft cloth to remove oils and buildup. For a deeper clean, soak in warm water with a few drops of mild dish soap, gently brush with a soft-bristled brush, then rinse and dry thoroughly. Remove gold jewelry before swimming, showering, or applying lotions and perfumes, as harsh chemicals can dull its shine over time. Store each piece separately in a soft pouch or lined box to prevent scratches.

Diamond Jewelry
Diamonds are brilliant by nature, but everyday wear can leave them looking cloudy. Restore their sparkle by soaking in a solution of warm water and mild dish soap, then gently cleaning around the stone and setting with a soft brush. Rinse well and pat dry with a lint-free cloth. Avoid touching the diamond directly, as natural oils from your skin can diminish its brilliance. Have your settings checked periodically by a professional to ensure stones remain secure.WatchesWipe your watch down with a soft, dry cloth to remove dust and moisture after wear. Keep it away from extreme temperatures, magnets, and prolonged direct sunlight, which can affect performance and appearance. If your timepiece is water-resistant, avoid pressing buttons or adjusting the crown while underwater, and rinse with fresh water after any exposure to salt or chlorine. Store your watch in a protective case or box, and have it serviced periodically to keep it running smoothly for years to come.

General Tips
Always remove your jewelry and watches before exercising, cleaning, or handling harsh chemicals. When you're not wearing them, store each piece individually to avoid scratches and tangling. With a little regular care, your pieces will retain their beauty and brilliance for a lifetime.
