Seagull ST2130 In-House Movement

The ST2130 is a Seagull in-house automatic caliber — a higher-specification movement than the Miyota 8215 used in the LOBINNI 19020 and Miyota 8217 in the 19015. Seagull manufactures movements at its Tianjin facility — the ST2130 is a core Seagull dress automatic with decorated movement architecture appropriate for display through an exhibition caseback.

Using the ST2130 places this watch in the same movement category as the Seagull 816.423 — Seagull’s own caliber rather than a Japanese third-party movement.

Push-Button Hidden Clasp

The leather strap uses a push-button hidden (deployant) clasp — the clasp folds flat against the strap and opens with simultaneous side-button presses. This provides more secure closure than a standard pin buckle (the clasp doesn’t accidentally release) and preserves the leather strap’s appearance by not creating a single fold point at the buckle tongue.

LOBINNI Range — Movement Hierarchy

The three LOBINNI automatics at Jewelry Addicts use different movement tiers:

The Business Date is the only LOBINNI model at Jewelry Addicts using a Seagull in-house caliber — distinct from the Japanese Miyota movements in the 19015 and 19020.

Who Is the LOBINNI Business Date For?

The Business Date is built for:

• Seagull in-house movement buyers who want Seagull’s own caliber on a LOBINNI dress watch with leather strap
• Rose gold case buyers who want the warm-tone case on a Seagull automatic at this price
• Push-button deployant clasp buyers who want the secure hidden clasp on a leather strap dress watch
• LOBINNI brand buyers who want the highest-specification movement in the brand’s dress watch range

How It Compares

vs. LOBINNI 19015 Miyota 8217 — The 19015 uses Miyota 8217 with 24-hour sub-dial and decorative disc. The Business Date uses Seagull ST2130 in-house with simpler dial. Choose 19015 for the 24-hour complication; choose Business Date for the Seagull in-house caliber.

vs. Seagull 816.423 Moonphase — The Seagull 816.423 uses ST21 with moon phase + power reserve + pointer date on steel bracelet. The LOBINNI Business Date uses ST2130 with date only on leather strap. Both use Seagull in-house movements — different complication levels and strap types.

vs. AGELOCER Budapest Cal.A4610 — AGELOCER uses its own Cal.A4610 at 40mm/10mm with 80-hour reserve. LOBINNI uses Seagull ST2130 — different in-house movement brands at similar price and dress character.
