A poetic reinterpretation of Seiko’s asymmetrical design heritage, the Seiko 4N00-3740—endearingly known as the “Halfmoon Piano”—captures the essence of sculptural timekeeping with a refined, avant-garde spirit. Drawing inspiration from the now-iconic Halfmoon series that defined Seiko’s bold 1990s experimentation, this piece mesmerizes through its undulating gold-tone bracelet that echoes the lyrical flow of piano keys. Its gently arched case cradles a luminous mother-of-pearl dial, offering a visual symphony of texture, light, and movement. More than a watch, it is a statement of quiet opulence—an objet d’art for the wrist that speaks to those who value rarity, grace, and timeless expression.

Fits wrist size up to 19 cm
