Omega Seamaster Planet Ocean Deep Black GMT 45.5MM – VSF Master Chronometer Cal.8900 V2

Engineered by VS Factory (VSF) for collectors who care as much about what’s under the caseback as what’s on the dial, the Omega Seamaster Planet Ocean Deep Black GMT 45.5MM – VSF Master Chronometer Cal.8900 V2 pairs a Solid 904L Oystersteel (Satin & Mirror Finished) exterior (45.5MM × 12.1mm (Bi-directional 24-Hour Bezel)) with the cloned Dandong DD3285 True GMT with Independent Hour Hand movement (70-Hour Reserve (28,800 vph)).

Calibre Stability, Power Reserve & Case Finishing

The winding stem engages with a firm, positive click across every setting position, and the hands advance with zero backlash. Sealed behind a scratch-resistant sapphire crystal and triple-checked gaskets, it’s built for daily wrist rotation rather than sitting in a display box.
