The Nivada Grenchen Antarctic began as the Aquamatic, a watch worn during Operation Deep Freeze (1955-56), the U.S. expedition led by Admiral Byrd to set up permanent research stations in Antarctica. Nivada Grenchen, founded in Grenchen in 1926, then put the name Antarctic on the dial. Today the Antarctic watch comes in several lines.

Antarctic sizes and movements FAQ
Which Antarctic size should I choose?
The 35 mm keeps the size of the 1950s original and is 10.1 mm thick. Most 38 mm models measure 45 mm lug to lug and take a 20 mm strap.
Are Antarctic watches automatic or hand-wound?
Both. The Antarctic 35mm, the Spider 35mm and the Glacier 35mm are hand-wound. The 38 mm models, the Diver and the GMT are automatic.
How water resistant is the Antarctic?
5 ATM on the 35 mm models and the GMT, 10 ATM on the 38 mm models, and 20 ATM on the Antarctic Diver.
What is the difference between the Antarctic and the Super Antarctic?
The Super Antarctic continues a later vintage model that a follower shared on Instagram. It has a gold medallion caseback, applied indexes and 3.6.9 dial options, mostly in 38 mm.
Nivada Grenchen’s Antarctic: A Watch Forged in Ice and History
In the world of horology, some watches stand out not only for their design, but for the stories they carry. The Nivada Grenchen Antarctic Collection is one of them, a Swiss timepiece shaped as much by craftsmanship as by extreme conditions. Introduced in the mid-1950s, the Antarctic was built on the success of the Nivada Aquamatic, a robust, automatic, and waterproof watch. While developed in a Swiss workshop, its reputation was forged in far harsher environments including the unforgiving conditions of the South Pole. This connection to one of the most ambitious polar expeditions of the 20th century helped define the Antarctic’s legacy. Today, the collection remains true to its origins, combining vintage-inspired design, Swiss mechanical reliability, and a spirit of exploration that still feels relevant decades later. .
Operation Deep Freeze: A watch put to the test
Between 1955 and 1956, the United States launched Operation Deep Freeze I, a scientific mission led by Admiral Richard Byrd. The objective was to establish permanent research stations in Antarctica, marking a significant step in international cooperation and scientific exploration on the frozen continent.
During this mission, members of the U.S. navy wore the Nivada Grenchen Aquamatic, exposing the watch to extreme conditions that few timepieces had ever faced. The watch endured sub-zero temperatures, constant exposure to ice and water, and the relentless challenges of polar exploration; yet, it maintained accuracy and reliability.
Vintage Models - AQUAMATIC
The success of the Aquamatic in these harsh conditions was a turning point for Nivada Grenchen. Recognizing the historical significance and performance of the model in Antarctica, the brand decided to rename the watch « Antarctic » on the dial, marking its transformation from a waterproof automatic to a true explorer’s watch.
This reliability earned the Antarctic a distinct place in watchmaking history, as one of the first wristwatches to reach and perform in the Antarctic, while also demonstrating the growing importance of tool watches in real-world applications.
A Watch for Harsh Conditions & Everyday Wear
While the Antarctic proved its worth in the extremes of the South Pole, it was never intended solely for explorers. Designed as a versatile, everyday timepiece, it struck a balance between durability and elegance, making it just as suitable for urban settings as for rugged environments.
From a design perspective, the original 35mm case housed a dial that featured Art Deco-style numerals, faceted markers, and thick bezels; these elements reflected the aesthetics of the time. Luminous hands and markers ensured visibility in low-light conditions, while its automatic movement provided reliability without the need for manual winding. Over the years, these characteristics became hallmarks of the collection.
The Evolution of the Antarctic
A Resurgence in the 21st Century
The revival of Nivada Grenchen in 2018 brought with it the return of some of its most storied models, including the Antarctic, Chronomaster, and Depthmaster. Today’s Antarctic collection remains faithful to the spirit of the original, maintaining its understated elegance and rugged reliability while integrating subtle refinements suited to modern expectations.
A Watch defined by endurance
Though the Antarctic was once a tool for explorers facing the extremes of the South Pole, its legacy extends far beyond historic expeditions. It reflects a time when watches were tested in real-world conditions where precision, durability, and reliability truly mattered.
Whether worn in harsh environments or as part of daily life, the Antarctic remains a watch that carries a story. A story of adventure, endurance, and design built to last, and meant to

FAQs
The Antarctic is a Swiss vintage-inspired watch collection introduced in the mid-1950s, built on the success of the Nivada Aquamatic, a robust, automatic, and waterproof watch. Its reputation was forged during one of the 20th century's most ambitious polar expeditions, and the collection has since become one of Nivada Grenchen's most storied lines.
The Antarctic began as the Nivada Aquamatic. After the watch proved its reliability during a U.S. Antarctic expedition, Nivada Grenchen renamed it "Antarctic" on the dial, marking its transformation from a waterproof automatic watch into a true explorer's watch.
Operation Deep Freeze I was a U.S. scientific mission carried out between 1955 and 1956, led by Admiral Richard Byrd, aimed at establishing permanent research stations in Antarctica. During this mission, U.S. Navy members wore the Nivada Grenchen Aquamatic, exposing it to sub-zero temperatures and constant contact with ice and water.
The Aquamatic endured extreme cold, ice, and water exposure throughout the expedition and maintained its accuracy and reliability, becoming one of the first wristwatches known to reach and perform in Antarctica.
The original Antarctic featured a 35mm case with a dial showcasing Art Deco-style numerals, faceted markers, and thick bezels, along with luminous hands and markers for visibility in low-light conditions. It was powered by an automatic movement, removing the need for manual winding.
No. While it proved itself in the extremes of the South Pole, the Antarctic was designed as a versatile, everyday timepiece, balancing durability and elegance for both rugged environments and daily urban wear.
The Antarctic line has evolved through several generations, from the original Aquamatic and 1950s Antarctic to the Antarctic I, II, III, and IV, and later additions such as the Antarctic Diver and Antarctic GMT, each building on the collection's core design heritage.
The Antarctic returned as part of Nivada Grenchen's brand revival in 2018, alongside other storied models like the Chronomaster and Depthmaster, staying faithful to the original's spirit while adding subtle modern refinements.
The Antarctic holds a distinct place in watchmaking history as one of the first wristwatches to reach and perform in Antarctica, demonstrating early on the real-world importance and reliability of tool watches.
Today's Antarctic collection is praised for its vintage charm, slim case, and everyday wearability, blending Nivada Grenchen's polar exploration heritage with an understated design.
