The Original Magnum P.I. Watch
In the early 1980’s, CBS launched the TV series Magnum PI. Set in Hawaii, it starred Tom Selleck. The series consistently ranked in the top 20 U.S. television programs for several years, finishing as high as number 3 for the 1982–83 season. And the watch that Tom Selleck wore for the first 3 seasons? Of course, it was the original Chronosport Sea Quartz 30.
We believe in sustainability through durability. Solar-powered watches require less servicing and result in less batteries used over the product's lifespan. With solar watches, we also provide a 6-year warranty out the box, no 2-year service intervals required. The solar movement charges in any light, allowing the Eclipse to run for up to 6 months in pitch darkness.
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.
