Sea Quartz

Before founding Momentum, Simon owned and operated a brand called Chronosport. Chronosport famously made watches worn by Tom Selleck in Magnum PI, Sylvester Stallone in Rambo III, and many military groups around the world. Chronosport is also credited with making the first quartz dive watch, the Sea Quartz 30.

The Sea Quartz Collection are watches inspired by the Chronosport, under the Momentum brand.
