Omega Planet Ocean 600m GMT 43.5mm Black Dial

Put the Omega Planet Ocean 600m GMT 43.5mm Black Dial on a digital scale next to a boutique example and the numbers match within a fraction of a gram. Machined by VS Factory (VSF) from Solid 904L Oystersteel (Satin & Mirror Finished), this reference pairs a 43.5MM × 12.1mm (Bi-directional 24-Hour Bezel) silhouette with an anti-reflective sapphire crystal that eliminates milky edge distortion. Inside beats the Dandong DD3285 True GMT with Independent Hour Hand (70-Hour Reserve (28,800 vph)), giving the seconds hand a crisp 28,800 vph (8 ticks per second) sweep.

Where cheaper builds cut corners on bracelet articulation and rehaut laser etching, VS Factory (VSF) chamfers the underside of every link so the watch drapes naturally across the wrist. The crown threads down onto twin Viton O-ring seals without grit or play, and the dial markers sit dead-center against the minute track under 10x loupe magnification.
