The revitalized Nivada Grenchen has made a splash through its startlingly accurate reissues of its famous Chronomaster, Chronoking, Depthmaster, and Antarctic collections. With their latest release, they’ve gone back to the Jet Age with the Antarctic GMT, a rare reference produced for just a few years in the early 1970s.
The revived Antarctic GMT features a brushed 36mm cushion-shaped stainless steel case true to the 1970s original. This simple design is radically accented by the Antarctic GMT's twin crowns, based on the original EPSA Super-Compressor case, though the reissue does not use this technology. The GMT scale is rendered through an internal rotating bezel operated by the top crown. Its dual-tone black and yellow scale is true to the past, offering a unique splash of color. The Antarctic GMT is available in black and tropical dial variants, the latter a limited edition of just 99 pieces, and is paired with a matching brown leather racing strap that oozes vintage charm.
Underneath the Antarctic's engraved Penguin caseback is a Soprod C125, a Swiss-made automatic caliber featuring an independent 24-hour hand “caller” GMT complication, date, 25 jewels, hacking, hand winding, a frequency of 28,800 beats per hour, and a power reserve of at least 42 hours.
