El reloj es de excelente calidad y una apariencia deportiva, pero sobria. Luce muy bien y su construcción es muy fuerte. La caratula blanca es delicada y las marcas de hora azules cambian a un celeste brillante, según la incidencia de la luz. El mecanismo es muy preciso. Lo compre de hace un mes y he estado verificando la hora con un reloj de referencia en linea y no ha tenido variación. Lo mantengo en una caja enrrolladora automática.

Excellent watch!

Rapid delivery and processing (domestic US). It's a Hamilton...I was surprised by the weight of this timepiece compared to my Seiko GMT. I love the 24-hour on the dial when dealing with military time.
