Description:
The Seiko Prospex Speedtimer reference HBJ003 combines the motorsport-inspired character of the Speedtimer collection with the everyday convenience of Seiko's V192 solar chronograph movement.
The 41.4mm stainless steel case is fitted with a green-and-black tachymeter bezel insert, paired with a green dial, LumiBrite-coated hands and indexes, and a curved sapphire crystal with anti-reflective coating on the inner surface. The chronograph times up to 60 minutes in 1/5-second increments, complemented by a 24-hour sub-dial, small seconds hand, power reserve indicator, and date display.
Powered entirely by light, the Calibre V192 can operate for approximately six months when fully charged, with an accuracy of ±15 seconds per month. Water-resistant to 100m, the watch is fitted on a stainless steel bracelet with a three-fold clasp and push-button release, and features a screw-down case back.
