Seiko quartz chronograph, calibre 8T63, reference 8T63-00D0, running – gloss black dial with gold-coloured hands and markers, 60-minute, small-seconds and 24-hour registers, date at 4.30, tachymeter bezel, 10 bar, on its original Seiko steel bracelet. [IMPORTANT – PLEASE READ] The bracelet is short and cannot be made longer. As linked it fits a wrist of approximately 150 to 160 mm, and no spare links are included, so it will not fit a larger wrist without sourcing additional links. Please check your wrist size before bidding. PLEASE NOTE: the code AL20901 in the seller's own title is not engraved anywhere on the watch – it is the seller's stock number; the serial number engraved on the caseback is 610498, and that is the number quoted below. No model or line name appears on the watch – the dial reads SEIKO and CHRONOGRAPH only – so none is claimed here. The code printed at the foot of the dial, 8T63-00E8, differs from the case code 8T63-00D0 engraved on the caseback: on Seiko watches the dial code identifies the dial and the case code identifies the case, so the two are not expected to match and the difference is not a sign of a replaced part. The caseback is marked WATER RESISTANT 10 BAR, but the gaskets have never been tested or replaced, so the water resistance is not guaranteed and the watch should be kept away from water. The crystal is not marked as sapphire anywhere, so no claim is made about its material. The chronograph hands sit correctly at zero, but the start, stop and reset functions have not been operated. The case diameter has been measured with a caliper at 40 mm. The lug width has not yet been measured and is given below as an approximation. Overview A Seiko quartz chronograph on the 8T63 calibre in stainless steel with gold-coloured accents: gold-coloured faceted bar markers, gold-coloured hands throughout, and a gold-coloured crown and pushers against a brushed steel case and a fixed tachymeter bezel. The dial is a gloss black that reads as a deep black face-on and throws a cool highlight when the light catches it, carrying SEIKO and CHRONOGRAPH in gold below 12 and three registers: a 60-minute counter at 10, the running seconds at 6 and a 24-hour indicator at 2. The central chronograph seconds hand reads against a 1/5-second track at the edge of the dial. The date sits at the 4.30 position, white on black. The solid screw-down caseback is engraved with the case code and the serial number, and the bracelet is the original Seiko three-row bracelet with a polished centre row and brushed outer links, with SEIKO on the clasp.

Very fine scuffing on the brushed outer links from normal wear. The clasp closes and latches correctly. Stretch could not be assessed from the photographs. Working order The watch is running. The small seconds hand at 6 o'clock was checked against the timestamps of four photographs spanning 14 seconds: across the three intervals of 7, 3 and 4 seconds it advanced by about 7, 4 and 4 seconds respectively, so it is keeping time in one-second steps with no interruption. The central chronograph seconds hand and the 60-minute hand sit at zero in every frame, and the 24-hour hand agrees with the time shown. The chronograph start, stop and reset functions, the date changeover, the timekeeping accuracy and the water resistance have not been tested with equipment, and the battery's remaining life is unknown.
