Omega Planet Ocean Chrono 45.5mm OMF Gray Dial Orange/Black Rubber

Put the Omega Planet Ocean Chrono 45.5mm OMF Gray Dial Orange/Black Rubber on a digital scale next to a boutique example and the numbers match within a fraction of a gram. Machined by OM Factory (OMF) from Solid 316L Stainless Steel (Satin & Mirror Finished), this reference pairs a 45.5MM (1:1 Omega Case Architecture) silhouette with an anti-reflective sapphire crystal that eliminates milky edge distortion. Inside beats the Co-Axial Master Chronometer Automatic Clone (28,800 vph) (55–60 Hour Power Reserve (28,800 vph)), giving the seconds hand a crisp 28,800 vph (8 ticks per second) sweep.

Calibre Stability, Power Reserve & Case Finishing

Where cheaper builds cut corners on bracelet articulation and rehaut laser etching, OM Factory (OMF) 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.
