Collection: Tissot Seastar

The Tissot Seastar is the brand's dive watch line, built for genuine underwater durability while staying versatile enough for everyday wear on land. The Seastar name has been part of Tissot's catalog since the early 1960s, and today's Seastar 1000 carries that heritage forward as a serious, professional-minded diver rather than a purely stylistic sport watch.

The Seastar 1000 delivers 300 meters of water resistance across the lineup, paired with a rotating dive bezel and scratch-resistant sapphire crystal, in case sizes ranging from a compact 36mm up to a bold 45.50mm chronograph. Movement options span quartz, automatic Powermatic 80 (with an 80-hour power reserve), and quartz GMT for tracking a second time zone, giving buyers a genuine range of price points and complications within one collection. Cases come in stainless steel, yellow gold PVD, and two-tone finishes, with dial options from classic black and silver to mother-of-pearl with diamond hour markers, making the Seastar equally suited to a rugged everyday diver or a dressier water-resistant option.

King Jewelers carries a wide range of Tissot Seastar 1000 watches, including 36mm, 40mm, and 43mm three-hand models, the Seastar 1000 Chronograph, and the Seastar 1000 Quartz GMT. Our team can help you compare sizes and movements in person at our Green Hills showroom in Nashville or online at kingjewelers.com.

1938-1952: Building Toward a Water-Resistant Icon
The Seastar's roots trace back to the 1930s, when Tissot partnered with the Swiss Laboratory for Watchmaking Research of Neuchâtel to develop genuinely water-resistant timepieces, resulting in the "Camping" (1938) and "Aquasport" (1939) collections, early watches that were shockproof, dust-tight, and fitted with unbreakable glass and stainless steel cases. That research eventually led to an improved, hermetically sealed waterproof watch, and Tissot registered "Seastar" as a trademark on December 13, 1952, giving the lineage its name.

Real Adventurers Put the Seastar to the Test
Unlike many dive watch histories built on marketing, the early Seastar earned its reputation through genuine expeditions. In 1956, a Seastar T12 model was chosen to accompany the release of Commander Jacques-Yves Cousteau's landmark film "The Silent World." In 1963, Nawang Gombu, an instructor at the Himalayan Mountaineering Institute in Darjeeling, wore a Tissot Seastar T12 on his ascent of Mount Everest, and Seastar T12 models continued to be tested by mountaineers climbing the Andes and Himalayas throughout the following years. In the 1960s, the "Seastar Seven" pushed the collection's technical progress further with a reinforced crystal and a single-piece case, refining the line into a slimmer, more graceful silhouette.

From Elegant Water-Resistant Watch to Serious Dive Instrument
The modern Seastar as a dedicated diver's watch took shape in the 21st century. Tissot relaunched the collection in 2003 with the Seastar 660, featuring a broad rotating bezel and 200-meter depth rating. In 2011, the Seastar 1000 Automatic Chronograph returned to the spotlight with a genuine 300-meter depth rating, a helium escape valve (more a statement of serious diving intent than a technical necessity at that depth), and screw-down chronograph pushers to prevent accidental activation underwater. The Seastar 1000 and Seastar 2000 lines were formally established in 2018, cementing the modern Seastar as Tissot's dedicated professional-minded dive collection.
