Most meteorite dials in watches are cut from one of two meteorites: Gibeon, found in Namibia, and Muonionalusta, found in northern Sweden. Both are iron-nickel, and both show a crosshatched crystal pattern once the surface is etched with acid. Jack Mason, a Texas brand, is using Muonionalusta for a limited edition of the Strat-o-timer GMT, the model it’s best known for, and it has a pretty nice color to it.

The steel case is 40mm wide and 13.2mm thick, with a lug-to-lug of 47mm and 20mm lugs. Those are sensible proportions for a GMT that's also dive capable. Water resistance is 200 meters with a screw-down crown, there’s sapphire crystals front and back, and the case and bracelet get a hardened coating to better resist scratches. The bezel turns both ways with 48 clicks. On the bracelet the watch weighs 160 grams.

The dial is a slice of the Muonionalusta meteorite, etched with acid to bring out the Widmanstätten pattern. Those crosshatched lines are iron-nickel crystals that formed as the metal cooled over millions of years, so no two of the 200 dials will look alike. Jack Mason calls the color icy blue, and it looks great. Hands and markers follow the standard Strat-o-timer layout and are lumed with BGW9.

Inside is the Miyota calibre 9075, an automatic running at 4Hz with 42 hours of power reserve and 24 jewels. It’s a flyer-style GMT, so the local hour hand moves in one-hour jumps without stopping the watch, while the 24-hour hand stays on home time. That is the setup you want if you actually travel. Jack Mason regulates each movement in-house to ±5 seconds per day, and final assembly happens in the United States. The steel bracelet tapers from 20mm to 16mm, uses quick-release bars, and has a clasp you can adjust without tools.
