Description
SEIKO SELECTION HFJ004P nano・universe SPECIAL EDITION
The SEIKO SELECTION HFJ004P is a women's solar watch created under the supervision of nano・universe. A black dial, gold-tone rectangular case and black leather strap give this Japanese Domestic Market model a compact, vintage-inspired appearance.
Classic Black and Gold-Tone Design
Distinctive contrast: The black dial is paired with gold-tone Roman numeral markers and slim hands. Its rectangular shape and rail-style minute track create a composed, classic look.
Leather detailing: A black cowhide leather strap with crocodile-style embossing complements the dial and fastens with a pin buckle.
Solar Caliber V115
Light-powered movement: Caliber V115 converts light into electrical energy stored in a rechargeable battery. It provides approximately 12 months of operation when fully charged, with an average accuracy of ±15 seconds per month.
Overcharge protection: The movement includes an overcharge prevention function. Regular exposure to light helps maintain sufficient charge.
Compact Stainless-Steel Construction
Slim proportions: The stainless-steel case measures 27.4 mm in length, 18.0 mm in width and 5.9 mm in thickness. Hardlex crystal protects the dial, and the watch weighs approximately 16 g.
Everyday protection: The HFJ004P offers water resistance for everyday use and magnetic resistance. It is not intended for swimming or diving.
