Sea-Gull

Sea-Gull (historically known as the Tianjin Watch Factory) is a colossal historic giant of global horology founded in 1955 in Tianjin, China. Operating as the largest manufacturer of mechanical watch movements in the world—producing roughly one-quarter of the planet’s total mechanical output—the brand holds an esteemed, legendary status among watch collectors. Rather than sourcing third-party parts, Sea-Gull relies on its massive internal manufacturing infrastructure, preserving a deep heritage that spans from building China’s first-ever domestic wristwatches to developing specialised military instruments for national defence.

Sea-Gull’s visual identity beautifully straddles two entirely different worlds: historic mid-century military nostalgia and high-end classical mechanical artistry. They are world-renowned for their authentic reissue designs, which confidently display retro typography, striking crimson dial accents, and traditional symbolic gold stars that celebrate their rich 1960s state-factory pedigree. The brand prioritises absolute mechanical visibility, frequently finishing their timepieces with transparent exhibition casebacks or open-heart apertures to proudly showcase their traditional watchmaking architecture.
