Seiko Chronograph 8T63-00D0 – gloss black dial, tachymeter bezel, 10 bar, stainless steel on a Seiko calf strap with deployant clasp, running A Seiko 8T63 quartz chronograph in stainless steel, the black-dial version of Seiko's Japanese domestic chronograph line, on a Seiko leather strap with a SEIKO deployant clasp. THE WATCH The dial is a gloss black with silver applied faceted bar markers, doubled at 12, and silver hour and minute hands with white luminous lines. Three black registers with silver rings carry a 60-minute counter at 9, a 24-hour indicator at 3 and the running seconds at 6, and the date sits at 4.30, white on black. The dial reads SEIKO and CHRONOGRAPH. The fixed black bezel carries a white tachymeter scale from 60 to 400. The case has polished sides and brushed lug tops, a grooved crown at 3 and two round pushers at 2 and 4, and a screw-down caseback engraved with the reference and serial. The strap is a black embossed Seiko calf strap, stamped SEIKO CALF on the back, with a push-button deployant clasp engraved SEIKO. WORKING ORDER The watch was running when checked and the seconds hand was observed advancing normally. The chronograph hands sit correctly at zero. Timekeeping accuracy, the date change and the chronograph functions have not been tested with equipment, and the battery life is unknown.
