Sea Quartz 30 – Eclipse Edition
A Legend Reimagined with Solar Power
First released in 1977, the original Sea Quartz 30 made history as the world’s first analog quartz diver’s watch, famously worn by Tom Selleck in Magnum P.I. and trusted by divers around the globe. Now, that iconic legacy returns with the Eclipse Edition, blending vintage design with cutting-edge solar technology.
Timeless Design, Modern Power
The Eclipse Edition stays true to the original with its distinctive vintage case, compact lug-to-lug fit, sapphire crystal, and dive bezel. What’s new is under the hood: a solar-powered Japanese quartz movement (Epson VS43A) that charges in any light. No more battery changes just reliable, maintenance-free timekeeping with quartz precision.

Inspired by Icons
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.
