Seiko Prospex Speedtimer Solar Chronograph Men's 41.40mm Watch HBJ003J

The Seiko Prospex Speedtimer HBJ003J is a solar-powered chronograph inspired by the Speedtimer racing watches of the 1960s and 70s. It has a green dial and a green-and-black bezel with a tachymeter scale, which gives it a sporty look that stands out from the usual black and steel chronographs. Inside is Seiko’s solar Calibre V192. It charges from any light, runs for about six months on a full charge, and never needs a battery change or winding. The chronograph times up to 60 minutes in fifth-of-a-second steps, and the dial adds a 24-hour hand, small seconds, a date window and a power reserve indicator. The 41.4mm stainless steel case has a curved sapphire crystal, and LumiBrite on the hands and markers for low-light reading. Water resistance is 100 metres, so it copes with swimming and everyday wear. The stainless steel bracelet closes with a three-fold clasp with push-button release. It suits weekends, travel and casual outfits for anyone who wants a colourful, ready-to-wear sports chronograph.
