From Jack Mason

The Strat-o-timer GMT celebrates one of the most iconic watches in history. Housing the highly anticipated Miyota 9075 automatic GMT movement, the Strat-o-timer marks the beginning of a new era of GMTs that features a jumping local hour hand. With a vision of becoming a legacy brand in our home state of Texas, the Strat-o-timer is assembled, and the movement regulated, in the USA.
