A Seiko Mod watch is a customized version of a standard Seiko watch. The term "MOD" comes from "modification". These modifications are generally made for those who want to personalize their watch according to their own taste.

USAMOD watches are powered by genuine Seiko movements sourced from trusted, verified suppliers. Our builds commonly feature reliable calibers such as NH34 (GMT), NH35, NH70, and VK63/VK64 chronograph movements.
