The ST2130 Movement — Seagull’s Proven Workhorse

The heart of the Ocean Star 1207 is the Seagull ST2130 automatic movement — 28 jewels, 28,800 vibrations per hour, and a 42-hour power reserve. This is the same reliable caliber powering the acclaimed Seagull 819.17 Bauhaus Automatic Watch and several other flagship models in the Seagull lineup, and it has earned a reputation for accuracy and longevity among collectors worldwide. One in four mechanical watches globally uses a Seagull movement — the brand’s manufacturing scale and expertise are simply unmatched in China and competitive with any movement producer in the world.

Specifications

Built for the Depths — 300M Rated

At 300 meters of water resistance, the Ocean Star 1207 meets the ISO 6425 diver’s standard in terms of depth capability. This is not a fashion watch with a water-resistant label — the ceramic bezel, solid caseback, screw-down architecture, and dense case construction are engineered for real underwater use. Whether you’re a recreational diver, a swimmer, or someone who simply wants a rugged daily watch that will never flinch around water, the Ocean Star 1207 is built for that life.

For comparison, other serious 300M divers available at JwlrAddicts include the STEELDIVE SD1954 Water Ghost, the Aquatico Dolphin Automatic Dive Watch, and the North Edge TRITON-Ti Solar Dive Watch for those who prefer a titanium and solar-powered option.

About Seagull — China’s Watchmaking Pioneer

Seagull has been manufacturing watches since 1955, accumulating a list of firsts that few brands anywhere in the world can match:

• 1955 — China’s first local watch manufacturer
• 1966 — China’s first self-designed watch movement
• 1973 — First Chinese watch brand to export internationally
• 2006 — First Chinese “Minute Repeater” watch
• 2010 — First Chinese coaxial dual-axis tourbillon

Today Seagull is the world’s largest producer of mechanical movements, with an annual output of 6 million calibers. Their movements power not just their own watches but those of numerous respected international brands. When you buy a Seagull timepiece, you are buying from the factory — not from a brand that outsources its movement.

Frequently Asked Questions

What movement does the Seagull Ocean Star 1207 use? The Seagull ST2130 automatic movement — 28 jewels, 28,800 vibrations per hour, 42-hour power reserve. It is an in-house Seagull caliber, the same movement used across several flagship models in the brand’s lineup.

Is 300M water resistance enough for scuba diving? Yes. 300 meters (30 bar) is well above the minimum threshold required for recreational scuba diving (typically rated to 100m or 200m). The ceramic bezel and solid caseback further reinforce the Ocean Star’s diving credentials.

What is the case diameter and will it suit my wrist? The case is 43.5mm in diameter with a 13mm thickness — a confident, substantial presence on the wrist. This size is ideal for medium to large wrists and fits the tool-watch aesthetic the Ocean Star projects.

What strap does it come on? It ships on a 22mm waterproof leather strap with a pin buckle. The 22mm lug width is standard, so aftermarket rubber, NATO, or steel bracelet options are widely available if you prefer a different wearing experience.

Does the watch require manual winding? The ST2130 is an automatic self-winding movement — it winds itself with normal wrist movement. If the watch has been sitting unworn for more than 42 hours, wind the crown manually 20–30 turns clockwise to get it running again before setting the time.

What is included in the package? One Seagull Ocean Star 1207 watch and one watch box.
