how to read time
A picture of the watch propped up on its side and a beam of light illuminating the top half of the abyss black dial. The dial displays the Ardra Labs logo and a superluminova-embossed GMT scale reading 0 in white, 0.5 in light blue and 0.75 in light green. These colors are reflected in the three-vertex minute hand, one of four sandblast-finished hands including a thin seconds hand, an oval-shaped hour hand leading with a pointy tip and a three-dot displaying Longines-railway style GMT hand, each dot one of the three GMT scale colors. The black Italian rubber strap is engraved with mini two-sided diamonds. A 24-hour bezel with a circular brushed finish frames the top of the case, which is finished with a straight-brush vertically. The lugs are sharp, with a polished edge-face on the insides. The crown sits on top.

GMT, complete.

There are few moments in horological history that evolve the art of timekeeping. The pioneering of the mechanical GMT movement in 1954 was one of them. For the first time, you could be away from home but carry its time with you.

The GMT movement was built on the foundations of Greenwich Meridian Time, conceived in 19th century Britain. But the mechanical GMT movement excludes about 1.6 billion people in 10 countries around the world. These countries have a unifying feature: they are non-standard GMT zones which can only be expressed in 30 or 45 minute offsets to the standard whole-hour GMT zones.

Indian Standard Time, for example, is GMT+5:30. Australian Central Standard Time would be GMT+9:30. If you were flying to Nepal (GMT+5:45) from Switzerland (GMT+1), you couldn't tell time in both places with your traditional GMT watch. Horology has seen efforts to capture these rogue time zones since 1954, but never as something more than a mechanical afterthought.

Until now.
