Before starting Momentum, our founder Simon and his family owned a watch company called Chronosport. In 1977, they launched one of the first-ever analog quartz diver’s watches, the Sea Quartz 30. The brand became so popular that it was soon sold in almost every serious dive store in the US and Canada. This watch was also famously worn by Tom Selleck in the first 3 seasons of the hit show Magnum PI. For many brands, quartz dive watches are an afterthought. We are proud of our quartz watches and believe they belong in every watch enthusiast’s collection.
Powered by a high-torque Swiss Ronda movement, the Sea Quartz 30 "Orca" Edition delivers an exceptional blend of precision and performance. Known for its accuracy and reliability, this Swiss-made quartz movement is built to withstand the demands of everyday wear, offering low-maintenance operation without sacrificing style. The movement's robust torque ensures smooth operation, especially for watches with larger hands, like the bold "Orca."
St. Moritz Watch Corp. designs, assembles and services high quality sports watches under the MOMENTUM® brand. As life becomes more active and a more casual style becomes the norm, our straightforward designs, with outstanding waterproof performance and no-BS pricing, resonate more and more with active people everywhere.
