About this watch

Omega Seamaster Diver 300M Co-Axial Master Chronometer Watch - 42 mm Steel Case - Unidirectional Bezel - Pvd Chrome Colour Ceramic Dial - 210.30.42.20.06.001

On the wrist, this 42mm ceramic case commands attention through its distinctive PVD chrome-colored ceramic dial, delivering the substantial presence that defines the modern Seamaster Diver 300M architecture. The laser-engraved wave pattern catches light with metallic precision against the industrial chrome finish, creating visual depth that shifts dramatically between desk and dive conditions. Reference 210.30.42.20.06.001 represents Omega's commitment to ceramic case construction, where the monobloc design eliminates traditional material transitions for seamless durability. Unworn condition preserves the factory-sharp edges and unblemished sapphire crystal that distinguish this Master Chronometer from circulation pieces.

“I purchased my first Porsche 911 from Brett. It was my first time purchasing a car without being able to see it in person and Brett made this process easy. He made sure I knew the exact condition of the car prior to finalizing the purchase.”
