    Relógio boa qualidade
    Envio rápido, 14 dias para chegar à minha casa no Brasil, interior de sp, qualidade do relógio é boa, nada de espetacular, mas mesmo assim vale a pena
    pelo preço pago, visto que vários lugares vendem o mesmo relógio por 200,00 , paguei 70,00 então valeu a pena, minha esposa está adorando
    vendedor rápido no envio após confirmação de pagamento.

    Relógio veio de acordo com o descrito
    O relógio é pequeno, mas para minha namorada ficou perfeito, já que o braço dela é fino! então, eu recomendo muito comprar, além de ser de acordo com o descrito, é muito confortável, bonito e leve, fora que troca a pulseira!! então, recomendo!!
