Big Idea Design Ti GMT
The Ti GMT is Big Idea Design's second watch with RZE, a limited run of 300 numbered pieces, and it pushes the formula towards travel. The Miyota 9075 is a true GMT movement, so the red 24-hour hand can be set independently for a second time zone, and a 48-click bidirectional bezel with a polished ceramic inlay adds a third. The whole dial is lumed in BGW9, so at night the entire face glows rather than just the markers. The case is Grade 2 titanium under RZE's UltraHex coating, 40.5 mm across, 13.3 mm thick and 46 mm lug to lug, and the watch weighs 53 g as a head or 74 g on its titanium bracelet. The bracelet's buckle is steel, so it is not nickel-free. It listed at $975 and has sold out at the maker.
