Zodiac Aerospace GMT

Zodiac Aerospace GMT

In the Jet Age, the sheer immediacy of jet travel—and the frequency at which transatlantic and transcontinental flights occurred—made it necessary for travelers to have a type of wristwatch that could display two timezones at once.

While the Rolex GMT Master is arguably the best-known of all wristwatches to emerge from this era, other manufactures raced to develop a wristwatch that could indicate a second time zone with a fixed 24-hour hand. 

Zodiac is perhaps best-known in today's vintage market for their chronographs, "poor man's Heuers" that have picked up quite a bit of traction in recent years. But Zodiac's list of accomplishments outside of chronographs is downright enviable. They produced flat pocket watches in the 1920's, some of the industry's earliest automatics in the 1930's, and power-reserve complications in the 1940's, to name a few accomplishments. 

In the mid-1950s, Zodiac, then a renowned and well-respected Swiss manufacture, introduced the Sea Wolf. The Sea Wolf is now considered to be among the first purpose-built dive watches to be manufactured, right alongside the Blancpain Fifty Fathoms and the Rolex Submariner. Like those other pieces, the Sea Wolf ushered in a unique design aesthetic (triangle hands and large triangular luminous plots at 3:00, 6:00, 9:00 and 12:00) that would become a hallmark of the brand in years to come.  

But what's often overlooked about the Sea Wolf is the case. Unlike most divers of the ere, the Sea Wolf featured a slim, well-proportioned case, decidedly small. Weighing in at almost 35mm wide and 11mm thick, the Sea Wolf was easily one of the smallest functional divers of the era.  

The success of the Sea Wolf ushered in a new era for Zodiac and allowed the brand to expand its design language to include other tool watches for different environs. The Aerospace GMT was one such piece. Building on a very similar case design, Zodiac constructed a pilot's watch with similar functionality as other, more commonly seen GMTs from other brands. The Aerospace GMT featured a 24-hour GMT function, window at 3:00 and a bi-directional rotating bezel.  

Like with the Sea Wolf, Zodiac's approach to Aerospace GMT was function-forward. The glossy black dial with fat silver markers and luminous plots makes the luminous stick hands stand out, and the simple red stick 24-hour hand with luminous tip is highly readable. Even the inclusion of a click bezel and white date well suggest careful considerate design for ease of use on the wrist, an attractive alternative to the more commonly-seen GMTs.
