Reference 210.30.42.20.03.002 delivers this replica Seamaster Diver 300M 210304 42mm 3002 in a classic stainless steel package with a blue ceramic dial and matching blue ceramic bezel insert. At 42mm the case follows standard Diver 300M proportions, and the steel bracelet includes the adjustable clasp system that Omega developed for comfortable fit without needing to visit a watchmaker. The blue colorway on this particular reference uses a wave-pattern laser engraving across the dial surface, producing the textured effect that became a Seamaster signature starting in 2018.

The omega seamaster 300m ceramic dial resists fading and scratching better than lacquered alternatives. Over years of UV exposure, ceramic retains its original color intensity where paint-based dials gradually shift.

What Collectors Notice

Blue-dial dive watches dominate the market, but the execution details separate them. On this reference the wave pattern follows a different frequency than earlier Seamaster generations, using broader, shallower waves compared to the tighter pattern from the pre-2018 dial design. The conical shape of the helium escape valve at ten o’clock integrates into the case contour more smoothly than the previous cylindrical design. Placed alongside the Seamaster Diver 300M 007 Edition, you can see how the same 42mm platform serves different design philosophies. The 007 leans into themed elements while this reference stays in pure diver territory. See more options in the Seamaster collection for direct comparison.

This vs Other Versions

The 210.30 steel references represent the core of the Diver 300M range, with the 003.002 dial code specifying this particular shade of blue. Steel versions weigh more than titanium alternatives but offer a different wrist presence that many buyers prefer. The polished and brushed finishing on the bracelet and case produces more light play than the matte titanium options. For buyers building a daily-wear dive watch rotation, this blue-on-blue configuration covers the most versatile color slot. This replica Seamaster Diver 300M 210304 42mm 3002 sits at the center of the collection as the reference most buyers compare everything else against.
