The Seiko HGK003P1 is a limited edition men's quartz chronograph created to celebrate Seiko's 145th anniversary — featuring a purple textured dial with contrasting silver sub-dials and gold accents on the logo and hands, a sapphire crystal, LumiBrite on the hands and indices, and a stainless steel bracelet with a safety folding clasp. Powered by the 8T63 quartz chronograph calibre, it delivers a 1/5-second chronograph measuring up to 12 hours, a 24-hour hand, and a date display — all in a strikingly angular 40 mm satin-finished case with an integrated bezel, 11.5 mm thickness, and 100 m water resistance. This is the sport-oriented counterpart to the women's HGH004P1 — same 145th anniversary purple-and-gold theme, but in a chronograph format with full lume and twice the water resistance.
