No era lo que esperaba
El reloj esta bien construido, y puede ser un gran reloj si te gustan de tamaño grande. El reloj tiene 42mm de diámetro pero, al no tener bisel y sus largas asas, parece que es de 44mm en la muñeca.
NO encajo con mis gustos, y el color del titanio no es para mi. Lo recibí, me lo probé y decidí devolver, parecía un reloj de bolsillo en mi muñeca.
Como adicional, espero esta vez me reembolsen el dinero completo señores de Amazon.
