Most buyers can spot a low-tier copy from across a table by its thick bezel lip and jerky 21,600 vph seconds hand. The Omega Seamaster 300M Master Chronometer Blue Dial by VS Factory (VSF) solves both: it runs the high-beat Co-Axial Master Chronometer Automatic Clone (28,800 vph) (55–60 Hour Power Reserve (28,800 vph)) inside a slim 42MM (1:1 Omega Case Architecture) housing milled from Solid 316L Stainless Steel (Satin & Mirror Finished).



### How VS Factory (VSF) Machines This Reference


From the font weight on the dial transfer printing to the micro-engraved clasp interior, every component is built to 1:1 tolerances. The sapphire crystal sits flush with the bezel ring and features internal anti-reflective treatment for zero-glare viewing.
