Built on VS Factory (VSF)'s dedicated assembly line, the Omega Seamaster 300M Co-Axial Master Chronometer brings together Solid 316L Stainless Steel (Satin & Mirror Finished) metallurgy (42MM (1:1 Omega Case Architecture)) and the 28,800 vph Co-Axial Master Chronometer Automatic Clone (28,800 vph) (55–60 Hour Power Reserve (28,800 vph)). Every curve of the lug profile and crown guard has been laser-scanned from the original reference.



### Inside the Co-Axial Master Chronometer Automatic Clone (28,800 vph) Architecture


Inside the clasp, the locking mechanism engages cleanly without rattle or sharp burrs. Above the dial, a Mohs-9 synthetic sapphire crystal with anti-reflective coating protects the hands and markers from everyday scuffs.
