Seiko Prospex Speedtimer Solar HBJ001P1

Motorsport at your fingertips. The two-tone aluminum bezel with a tachymeter scale underscores the watch's sporty character: a distinctive feature from the Speedtimer archive. The wide indices and characteristic hour and minute hands, both coated with LumiBrite, ensure excellent legibility even in low light conditions. The contrasting sub-dials stand out clearly against the main dial, making the chronograph readings easy to read at a glance. The sporty metal bracelet is custom-shaped for the 41mm case and tapers from the lugs towards the clasp, giving the watch a balanced yet impactful presence on the wrist.
