Sea-Gull watches: owner reviews and feedback

Sea-Gull traces its industrial origins to 1955 in Tianjin and occupies a unique position within Chinese watchmaking history: the company that emerged from the Tianjin Watch Factory is both a consumer watch brand and one of the world's largest manufacturers of mechanical watch movements. On March 24, 1955, a small team completed the Wu Xing or Five-Star, generally presented as the first mechanical wristwatch developed in the People's Republic of China. The industrial origin should nevertheless be distinguished from the Sea-Gull brand name itself: “Sea-Gull” began to be used internationally for exports in 1973, while Tianjin Seagull Corporation was formally established in 1992. Today Tianjin Seagull Watch Group designs and manufactures everything from straightforward automatic calibres to chronographs, tourbillons, double tourbillons, minute repeaters and other complications, with current annual movement production stated at more than two million units. Its watch catalogue now ranges from comparatively accessible automatics to split-seconds chronographs and tourbillons exceeding US$5,000.

1955, Project 304 and the gradual birth of the Sea-Gull name

The story effectively begins on March 24, 1955 in Tianjin with the completion of the Five-Star watch. This first piece was essentially experimental. The Wuyi or “May First” watch followed from 1957 and reached genuine serial production in 1958. Industrial development continued through the Tianjin Watch Factory, which became one of the principal centres of China's emerging watch industry.

The episode best known to collectors began in 1961 when Chinese authorities assigned the secret Project 304 to the Tianjin factory: development of an aviation chronograph for military use. The chronology is often simplified into the phrase “1963 chronograph”, but the project started in 1961, prototypes and qualification tests continued through the early 1960s and approximately 1,400 finished watches were finally delivered to the Chinese Air Force in 1966. The famous modern “1963” name was therefore not the historical commercial designation of the watch: the original piece was fundamentally the D304 chronograph of Project 304.

The mechanical origin of the chronograph also deserves precision. In the early 1960s Tianjin acquired from Swiss manufacturer Venus the blueprints, tooling and machinery used to produce the Venus 175 column-wheel chronograph as Swiss production was being discontinued. Chinese engineers then adapted the architecture, notably developing the original 17-jewel design into a 19-jewel movement. The modern ST19 is genuinely manufactured by Sea-Gull in China, but its historical architecture descends directly from the Swiss Venus 175 and should not be presented as a completely clean-sheet Tianjin invention.

In 1966 the factory also introduced Dongfeng, described as the first Chinese watch independently designed and industrially produced by its own engineers. This represented a different milestone from Five-Star: the 1955 watch demonstrated that domestic watch construction was possible, while Dongfeng reflected a much more mature Chinese industrial design capability.

The Sea-Gull name entered the international commercial story in 1973 when Tianjin watches began to be exported under that brand. Tianjin Seagull Corporation was subsequently formed in 1992. There is therefore strong industrial continuity from 1955, but three dates need to be distinguished: 1955 for the origin of Tianjin watchmaking, 1973 for international use of the Sea-Gull name and 1992 for the establishment of Tianjin Seagull Corporation.

During the early 2000s Sea-Gull resumed large-scale exploitation of the ST19 chronograph family while accelerating development of high complications. The company states that it completed its own tourbillon in 2005, a minute repeater in 2006 and China's first double tourbillon in 2007. In 2009 the ST9250 combined a tourbillon, minute repeater and perpetual calendar within one movement. These developments do not mean that every Sea-Gull receives equivalent finishing, but they demonstrate industrial capabilities far beyond those of a brand simply casing movements sourced from third parties.

A genuine movement manufacture, from ST2130 to tourbillons

Sea-Gull differs fundamentally from most Chinese microbrands through its ability to produce mechanical movements at enormous scale. The current international website states annual output exceeding two million movements, while an official Tianjin industrial profile indicates production capacity of up to three million movements and approximately 200,000 finished watches. Sea-Gull should therefore be regarded as a genuine industrial calibre manufacturer rather than merely a watch brand using Chinese movements.

Sea-Gull ST2130 is one of the most important automatic workhorse movements in the catalogue. It measures approximately 26 mm across and 4.8 mm thick, contains 28 jewels, runs at 28,800 vibrations per hour, offers hand winding and hacking seconds and provides approximately 40 hours of power reserve. It powers numerous three-hand watches and divers. Its construction reflects several classic Swiss automatic principles, but the movement itself is industrially manufactured by Sea-Gull.

Sea-Gull ST1901 remains the company's most iconic movement among international enthusiasts. This hand-wound column-wheel chronograph runs at 21,600 vibrations per hour and belongs to the ST19 family historically descended from Venus 175. Current executions can contain 22 jewels and receive different levels of decoration. The key attraction of ST1901 is that it provides a genuine mechanical column-wheel chronograph architecture at a cost dramatically below that of most comparable Swiss chronographs.

Sea-Gull is no longer limited to ST19. ST25-family movements support numerous automatic and multifunction configurations, while high-end collections use tourbillon movements genuinely developed within the group. The company possesses substantial in-house capability for plates, bridges, gear trains, mechanical components and complications together with a major technical development centre in Tianjin.

This industrial reality makes the term “manufacture” far more defensible for Sea-Gull than for companies simply renaming supplier movements. One qualification remains necessary: the ability to manufacture a complete movement internally does not necessarily mean every component of every Sea-Gull watch is made within the Tianjin factory. Cases, bracelets, crystals, decorative materials and selected components can naturally be sourced from specialist suppliers.

The current ultra-thin automatic tourbillon demonstrates the upper end of this capability. Sea-Gull Ultra-Thin Automatic Tourbillon 42mm uses calibre ST8610, a 34-jewel automatic tourbillon running at 28,800 vibrations per hour and delivering approximately 43 hours of power reserve. The movement itself is around 4.3 mm thick, allowing the complete watch to remain only 9.4 mm despite its 42 mm diameter. Stainless steel, sapphire, 50-metre water resistance and a US$4,999 price place this model in a substantially more ambitious category than the company's historically affordable watches.

Sea-Gull has also been developing more experimental technology. In 2024 it introduced a tourbillon using a proprietary silicon hairspring and free-sprung regulating system. This direction indicates that present-day R&D extends beyond reproducing established architectures toward new materials, anti-magnetism, energy efficiency and movement miniaturisation.

1963, Ocean, Rattrapante and Master: an exceptionally broad modern catalogue

• Sea-Gull 1963 Chronograph 70th Anniversary Reissue — hand-wound ST1901 chronograph, 37.3 mm, sapphire, 5 bar and approximately US$789.
• Sea-Gull 1963 Polar Night — 2026 chronograph with premium-finished ST1901, 37.3 mm, 5 bar and approximately US$999.
• Sea-Gull Ocean Series 200m 39mm — ST2130 automatic, 39 mm, 28,800 vph, sapphire, steel bracelet and 200 metres.
• Sea-Gull Ocean Series 300m — approximately 43.5 mm ST2130 diver with sapphire, ceramic bezel and 300-metre water resistance depending on reference.
• Sea-Gull Rattrapante 70th Anniversary — hand-wound ST1961, 42.5 mm, split-seconds complication, limited production and approximately US$4,299.
• Sea-Gull Meteorite Rattrapante — ST1961-2, Muonionalusta meteorite dial, Grade 5 titanium, 42.5 mm, 200 pieces and approximately US$5,299.
• Sea-Gull Ultra-Thin Automatic Tourbillon 42mm — automatic ST8610, 34 jewels, 4 Hz, 43 hours, 9.4 mm total thickness and approximately US$4,999.

Sea-Gull 1963 Chronograph 70th Anniversary Reissue provides the most direct route into the company's history. Its 316L steel case measures 37.3 mm across, approximately 47 mm lug to lug and 15 mm thick including the crystal, with sapphire and 5-bar water resistance. The hand-wound ST1901 runs at 21,600 vibrations per hour. Its official international price of US$789 is substantially higher than the many “1963” chronographs available from independent stores and marketplaces, reflecting in part the distinction between an officially distributed Sea-Gull watch and the many interpretations built around the same movement.

This distinction became particularly important in 2026. Sea-Gull now explicitly states that en.seagullwatch.com is its official international website and seagullwatch.com its mainland Chinese site, warning customers about websites using the Sea-Gull name without authorisation. The term “Seagull 1963” has become so widespread online that it can describe very different watches, sometimes containing a genuine ST19 movement but not produced or warranted by Sea-Gull itself. Collectors concerned with provenance, quality control and official after-sales support should therefore distinguish a Sea-Gull movement from a complete Sea-Gull watch.

The 2026 Sea-Gull 1963 Polar Night and Sea-Gull 1963 Aurora use a premium-finished 22-jewel ST1901 running at 21,600 vibrations per hour within the same 37.3 mm format. Pricing increases to approximately US$999. A 500-piece meteorite-dial edition costs US$1,599, demonstrating Sea-Gull's attempt to elevate its own 1963 collection beyond the image of an inexpensive Chinese chronograph.

At the opposite end of the use spectrum, Sea-Gull Ocean Series 200m 39mm provides a much more modern everyday proposition. Its steel case measures 39 mm across, 45.6 mm lug to lug and approximately 12.6 mm thick. ST2130 automatic mechanics provide 28 jewels and a 4 Hz frequency, while the watch includes sapphire, a steel bracelet and 200-metre water resistance. Current official pricing is US$879. Larger Ocean references offer 300-metre water resistance at lower prices, illustrating a catalogue in which pricing does not always follow specification alone.

Sea-Gull Rattrapante 70th Anniversary is one of the most technically interesting recent developments. ST1961 evolves from the ST1901 architecture by adding a split-seconds function that allows one chronograph seconds hand to be stopped independently before catching up with the other. Rather than using the traditional dual-column-wheel architecture found on some expensive Swiss rattrapantes, Sea-Gull uses cam actuation for part of the system to improve robustness, packaging and affordability. Power reserve is approximately 45 hours.

The rattrapante case measures 42.5 mm across and approximately 16 mm thick, with the 70th-anniversary version limited to 500 pieces. Its US$4,299 price is substantial but exceptionally low for a true mechanical split-seconds complication. The technical value is therefore genuine, although the industrial construction and finishing should not be equated directly with hand-finished Swiss rattrapantes costing several tens of thousands of dollars.

Sea-Gull Meteorite Rattrapante develops the concept further with a genuine Muonionalusta meteorite dial, Grade 5 titanium case and ST1961-2. The hand-wound movement contains 27 jewels and runs at 21,600 vibrations per hour. Production is limited to 200 pieces and official pricing reaches US$5,299. Warranty coverage is three years here, while many mainstream references continue to carry two years.

Real industrial power, but an international ownership experience still being rebuilt

Sea-Gull's greatest strength is extremely difficult for a small independent company to replicate: genuine large-scale control over mechanical movement manufacture together with the technical ability to build rare complications. The same organisation can produce an ST2130 sold independently for around one hundred dollars, an ST1901 column-wheel chronograph and a 4 Hz ultra-thin automatic tourbillon. This industrial breadth is probably the single most important characteristic of Sea-Gull.

Scale also explains why Sea-Gull movements appear inside many watches that do not carry the Sea-Gull name. ST19 is particularly common among international microbrands and assemblers, while other automatic calibres are also supplied externally. The reputation of a Sea-Gull movement must therefore be distinguished from that of a complete watch produced and quality-controlled by the Tianjin company.

The launch of the direct international website in 2025 represented an important strategic shift. For many years, buying a Sea-Gull outside China frequently meant dealing with distributors whose official status could be difficult to establish. The company is now attempting to regain control over international distribution, brand image, warranty and especially the highly popular “1963” identity.

Warranty coverage currently varies between collections. Many mainstream references including 1963 and Ocean provide two years, while selected high complications and premium models receive three years. The international website also provides a 30-day return period. Warranty should therefore be confirmed reference by reference rather than assuming one universal policy across the almost two hundred variants currently listed globally.

Movement parts availability is theoretically a major ownership advantage. Sea-Gull manufactures its own calibres and even sells selected complete movements such as ST2130 directly. Straightforward movements can therefore often be repaired or replaced without disproportionate difficulty. ST8610, ST1961 and double-tourbillon complications will naturally require far more specialised Sea-Gull service or watchmakers familiar with those particular mechanisms.

Quality control remains a more nuanced subject. Sea-Gull's manufacturing capability is unquestionable, but the group covers an exceptionally broad range of products and movement grades. Historical reports surrounding inexpensive wholesale movements should not automatically be applied to today's premium watches, but the reverse is equally true: the sophistication of a Master tourbillon does not mean every ST19 supplied to an external assembler receives the same regulation, decoration or final quality control.

The secondary market remains driven primarily by ownership value rather than investment. Official 1963 references have genuine recognition among enthusiasts, but the abundance of competing interpretations reduces scarcity. Sea-Gull tourbillons offer remarkable complications for their prices but have a much less liquid pre-owned market than established Swiss or Japanese luxury brands. Limited editions can become difficult to find without necessarily appreciating financially.

The company becomes particularly interesting when viewed through industrial history. A Sea-Gull represents the transformation of a country from an emerging watch industry into one of the world's largest producers of mechanical movements within only a few decades. ST19 carries a Swiss-to-Chinese lineage, ST2130 represents modern industrial scale and ST8610 or ST1961 demonstrate an increasingly ambitious approach to high complications. Few brands allow one catalogue to illustrate so much of the evolution of an entire national watchmaking industry.

Sea-Gull's principal challenge is therefore no longer proving that it can manufacture movements. That capability has long been established. The task now is to bring finished-watch quality, international distribution, after-sales service and catalogue clarity to a consistently high enough level that the Sea-Gull brand itself fully benefits from the technical reputation of the manufacturing group behind it.

Conclusion

Sea-Gull is far more than a Chinese brand offering affordable mechanical watches: it is one of the major industrial forces in global mechanical watchmaking and has continuous manufacturing roots reaching back to the beginning of the People's Republic of China's watch industry in 1955. Its history nevertheless requires precision: the first Five-Star appeared in 1955, military Project 304 began in 1961 and ultimately led to the delivery of 1,400 aviation chronographs in 1966, the movement that became ST19 descends from the Swiss Venus 175, and Sea-Gull did not become the export brand name until 1973. Today the Tianjin company genuinely manufactures its own movement families, from ST2130 and ST19 chronographs to tourbillons, double tourbillons and split-seconds calibres. The 1963 remains the strongest historical reference, Ocean provides a more modern and robust alternative, while ultra-thin ST8610 and ST1961 rattrapante demonstrate substantially greater technical ambition. The principal points of caution are the large number of unofficial sellers, differences in finishing between product tiers, warranty periods varying from two to three years and resale values that remain modest compared with major Swiss brands. For collectors who prioritise mechanics and industrial history over logo prestige, however, Sea-Gull offers a combination of technical depth, authentic heritage and pricing that is almost impossible to replicate elsewhere.

To compare that industrial capability with real-world ownership, Dialicious customer reviews make it possible to evaluate accuracy, ST19 and ST2130 reliability, comfort, finishing quality, complication performance, durability, after-sales service and value for money.
