Sea-Gull is a watch brand founded in 1955 in Tianjin, China. Evolving from the Tianjin Watch Factory (now Tianjin Sea-Gull Watch Group), it manufactures mechanical watches and movements for audiences ranging from first-time buyers to collectors seeking more ambitious complications.
Born as a state-owned factory, the brand went through the quartz era before returning to all-mechanical production, building around caliber families (ST16, ST18, ST21/2130, ST36, ST19, etc.); a key milestone was acquiring the tooling and blueprints of the Venus 175 chronograph in the early 1960s, which spawned the ST19 lineage, while the mid-2000s brought in-house tourbillons (ST80 and derivatives) and a spectrum from standard workhorse movements to sophisticated complications.
Part of the brand’s global recognition comes from a military-born piece turned cult classic: the “1963” derived from Project 304, a re-edition of a chronograph designed for the Chinese Air Force with a clean bi-compax layout and strong historic appeal; around it, Sea-Gull develops classic and sporty lines as well as tourbillons priced more accessibly than many Swiss counterparts.
Beyond its own watches, Sea-Gull broadly supplies movements: ST16 (a robust automatic with Japanese-inspired architecture), ST2130 (similar layout to ETA 2824-2), ST36 (hand-wound family akin to Unitas 6497/6498) and ST19 (column-wheel chronograph derived from the Venus heritage); this availability powers many micro-brands and international assemblers, supporting the company’s reputation as a major industrial supplier in Asia.
The positioning spans a wide range: entry-priced “classic” automatics, mid-range historic chronographs and higher-end complications (tourbillons, multi-axis); exact pricing varies by market and series (from a few hundred euros at entry level to several thousand for tourbillons), while annual volumes are not disclosed. Distribution mixes direct online sales, retail partners in China and abroad, and a B2B network for movements.
Sea-Gull appeals to those discovering mechanical watchmaking at a measured cost, to enthusiasts of engaging horological stories (1963), and to the curious seeking “de-dramatized” access to complications. The brand is identifiable by its ST caliber ecosystem, supplier role, and collections ranging from utilitarian daily pieces to technical showcases. To choose between a historic Sea-Gull 1963, a daily-driver automatic or a more demonstrative tourbillon, compare specifications with real-world use: rely on Dialicious customer reviews to assess legibility, comfort and on-wrist behavior.
