Time-Tested Tradition: The Fascinating History of Zodiac Watches

Zodiac watches have a rich history dating back to 1882. The company was founded by Ariste Calame in Le Locle, Switzerland, and started by producing pocket watches. In the early 1900s, Zodiac transitioned to producing wristwatches and quickly established itself as a leader in the industry. The company's watches were known for their precision and reliability, and were used by the military during World War I and World War II. 

In the 1950s, Zodiac introduced its first line of automatic watches, which were powered by the movement of the wearer's wrist. This was a significant innovation at the time, as it eliminated the need to manually wind the watch.

In the 1960s, Zodiac became known for its sporty and stylish watches, particularly the "Seawolf" line of diving watches. These watches featured a water-resistant case and a rotating bezel, which allowed divers to track their remaining air supply.

Throughout the 1970s and 1980s, Zodiac continued to innovate and introduce new lines of watches, including the "Astrographic" and the "Super Sea Wolf" which are highly sought after by collectors today.

In recent years, Zodiac has been re-launched by Fossil Group and the watches are now available in a wide range of styles and price points, from classic dress watches to modern, sporty designs. The company changed their "in-house" automatic movement in 2008.

Frequently Asked Questions: Zodiac Heritage & Engineering

Q: Is Zodiac actually an "in-house" brand?

A: In 2026, Zodiac is one of the few brands at this price point that can claim a vertical supply chain. Both Zodiac and STP (Swiss Technology Production) are owned by the Fossil Group. This means the STP 1-21 and 7-20 movements are designed and built specifically for Zodiac watches in Biel-Bienne, Switzerland, offering a level of movement exclusivity usually reserved for much more expensive brands.

Q: What is the new STP 7-20 GMT movement?

A: This is a major 2026 update. The STP 7-20 is a "True" or "Flyer" GMT movement. Unlike older "Caller" GMTs, the 7-20 allows you to jump the local hour hand independently when you change time zones. It beats at 28,800 BPH and provides a 40-hour power reserve, making Zodiac's GMT line one of the most technically capable in the sub-$2,000 category.

Q: Why does the Pro-Diver say "Diver's" on the dial while other Sea Wolfs do not?

A: To print "Diver's" on the dial, a watch must pass the rigorous ISO 6425 standard. This involves individual testing for water resistance (at 125% of the rated depth), thermal shock, and magnetic resistance. The Super Sea Wolf Pro-Diver is the only model in the line that undergoes this full certification process, distinguishing it from the standard "Compression" models which are rated for recreational use.

Q: What is the significance of the "Manta Ray" case on the Zodiac Olympos?

A: The Olympos is a "Heritage" model originally released in 1961. Its unique asymmetrical case (shaped like a Manta Ray) was an early attempt at an ergonomic design that moved the crown to the 2 o'clock position to prevent it from digging into the wrist. In 2026, it remains one of the few "dress-tool" watches that offers a vintage aesthetic with a modern STP 1-11 automatic heart.

Q: How does the Sea-Chron differ from a standard chronograph?

A: The Sea-Chron is a "Dive Chronograph." In 2026, it has been revitalized to include a ceramic bezel and a high-performance Sellita SW510 M movement. It is technically more robust than a standard racing chronograph, featuring a 200m depth rating and screw-down pushers to ensure the movement stays dry even if you use the timing functions near the water.
