The Seiko HGH004P1 is a limited edition women's quartz watch created to celebrate Seiko's 145th anniversary — featuring a purple/violet dial with Roman numeral markers, a gold-toned seconds hand and Seiko logo, a sapphire crystal, and a stainless steel bracelet with a safety folding clasp. Powered by the 6N01 quartz calibre with ±15 seconds per month accuracy and a 3-year battery life, it delivers the reliability of Seiko's quartz engineering in a refined 29.6 mm case that is just 6.19 mm thick — slim, comfortable, and understated enough for everyday wear while carrying the significance of a numbered anniversary edition.
