*Preorders will reopen soon.* 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 will be our first watch of many to come that will be assembled, and the movement regulated, in the USA.

We offer free shipping on all orders over £246.00. All orders placed before 1 pm CST Monday - Friday will ship that day. Orders placed after 1 pm CST will ship on the following Business day.

Checks Every Box

The Strat-o-timer GMT is loaded with top of the line specifications and was completely designed at our studio in Texas. This watch was held to the highest of standards.

Miyota Caliber 9075

This self-winding movement has a 42 hour power reserve, 24 jewels, and 28,800vph. Its functions include a GMT with jumping local hour, which is functionally identical to a Rolex GMT-Master II and is generally only reserved for watches in higher price ranges.

Regulated & Assembled in America

We are bringing watch assembly closer to home in order to have full ownership over quality control. Every Strat-o-timer GMT has been regulated to an accuracy of +/- 5 seconds per day. Without regulation, the movement’s stock accuracy is +30/-10 seconds per day.

Vintage Inspired Sapphire

The Strat-o-timer GMT sports a sapphire crystal that is raised above the bezel by a few millimeters as an homage to vintage watches that used acrylic crystals. We’ve recreated this look with a sapphire crystal in lieu of acrylic to increase the durability and reduce any potential scratching. Multiple layers of AR coating have been applied to the underside of the crystal.

Read the Lume

To increase low-light legibility, Swiss Super-LumiNova® has been added along the bezel, dial, and hands. The bezel has 7 layers of printed lume and the indices are filled with lume for a deeper, longer lasting glow.

The Perfect Fit for All Wrists

The 7-row, 316L stainless steel bracelet has a comfortable 20mm to 16mm taper and is equipped with solid, quick-release end links. The micro-adjust buckle seals the deal and ensures a great fit on wrists of all sizes.
