About Momentum
Founded in 1980 and based in Vancouver, British Columbia, Momentum (a brand of St. Moritz Watch Corp.) carved out a niche building honest, hard-wearing sports watches for active people rather than chasing luxury status. Its watches lean on Swiss Ronda quartz and increasingly solar-powered movements, sapphire crystals, and serious water resistance (often 200-300m), wrapped in models like the long-running Sea Quartz 30, the UDT and M50 divers, and the Atlas field line. Trusted by firefighters, military divers, and other professionals, Momentum has built a loyal following as one of the most underrated value-driven North American microbrands, assembling watches by hand in Vancouver and Blaine, WA.
