OMEGA Seamaster 300 has over 40 years history.This year it released the Seamaster 300 Master Co-Axial.The watch has a pitch-perfect blend of vintage styling and modern watchmaking technology that drew almost unanimous acclaim. There’s the narrow bezel resembling the 1957 original, but now uni-directional and ratcheting, crafted from scratch-proof LiquidMetal instead of fragile acrylic. 
The dial is a textured matte black with the familiar Seamaster script and triangular markers, which are done in a perfect faded yellow, as if the watch had been aging in a dive locker for 60 years, ridden hard and put away wet. It also lacks a date function, which hews to its ancestor’s original brief. While all that retro is enough to make a dive watch fan swoon, you’ve got to go deeper inside to truly appreciate why this watch is so special.
The “Master Co-Axial” part of the name refers to Omega’s calibre 8400, a twin-barrel self-winding movement with a co-axial escapement that defies the effects of friction better than conventional lever escapements. The movement, while utilitarian, is lovely to look at, with radially patterned bridges and a winding rotor that seem to magnify the movement. 
Omega chose to use a display case back on this homage to a classic in order to show off the calibre 8400’s pièce de résistance: the anti-magnetic technologies that render it impervious to magnetic influences. Proprietary alloys and a prodigious use of silicon resist the stereo speakers, limpet mines and shipwrecks that can wreak havoc on a watch’s accuracy. With no need for a soft iron movement holder, the movement can be admired in all its state-of-the-art glory while staying resistant to magnetism up to a CERN-worthy 15,000 Gauss.
