The fourth generation of the Omega Seamaster 300M was introduced at BaselWorld 2018, marking the return of the wave-dial and the introduction of the Co-Axial Master Chronometer caliber 8800. It is available in a number of variations; one of the more unusual among them being this 210.60.42.20.99.001, which features both a case and bracelet in a combination of titanium, tantalum, and Sedna-gold.
