User experiences

  1. "Stainless steel bezel and a stunning dial, coupled with a basic but reliable and robust movement."
    "Bisel en acero inoxidable y una esfera sensacional, unido a un movimiento básico pero fiable y robusto."
    Roberto Alcaín · August 23, 2025

    The watch meets my expectations. It had an unbeatable price. It came very very well adjusted from the factory.

    • The dial is sensational.
    • Like all Seiko of this level, it does not have a machined clasp, only a pressed sheet metal one.

    El reloj cumple mis expectativas. Tenía un precio inmejorable. Venía muy muy bien ajustado de fábrica.

    • La esfera es sensacional.
    • Como todo Seiko de este nivel, que no lleve el cierre mecanizado, solo de chapa prensada.
