The Martin M-130 China Clipper flew across the Pacific for the very first time in 1935, forever opening the skies to commercial flight. The aircraft was built by Glenn L. Martin Corporation in Baltimore, MD.

Our Martin Collection offers a series of timepieces based on vintage navigational instruments. Each limited edition below is rooted in American culture, history and innovation.


In 1999, a NASA astronaut commissioned Hartwig Balke to make a watch for his STS-99 mission. Our chronometers helped prove the efficacy of automatic movements in outer-space. Ever since, the same 7750 calibers have been used in each of the Mission Chronographs below.

Towson Watch Company Founders

“I started life as a watchmaker in 1948. Hartwig started out as an engineer. We work together well because he essentially does the design and engineering work that I can’t do. But I’ve had a lot of experience doing restoration of antique watches for museums. These are 200 to 300 year-old timepieces. We have both ends of the technical spectrum covered, from current engineering to an understanding of watchmaking 500 years ago.”
