This replica Seamaster 210304 green puts a 42mm stainless steel case behind a green ceramic dial, and the result is one of the more distinctive current-generation Diver 300M options. The 210.30.42.20.10.001 reference belongs to the full-steel family, with no gold accents or two-tone detailing. Omega introduced green into the Seamaster Diver palette as demand for non-traditional dial colors grew across the entire watch market. The shade here leans toward a deep, saturated tone rather than the bright or olive greens seen on some competitors.

Case & Movement Specs

• Case diameter: 42mm
• Case material: stainless steel
• Bezel: green ceramic, unidirectional, liquid metal scale
• Crystal: domed sapphire with anti-reflective treatment
• Dial: green ceramic with wave pattern
• Movement: automatic with co-axial escapement
• Water resistance: 300 meters

The bezel ceramic matches the dial tone, creating a color-coordinated look from bezel edge to dial center. The applied rhodium-plated indices provide contrast against the green surface, and the Super-LumiNova fill on the hands and markers glows green in the dark.

Caliber Breakdown

The movement inside this reference is the same automatic co-axial caliber used across the time-only Diver 300M range. It provides a central seconds hand, date function at 6 o’clock, and a power reserve in the 55-hour range. The free-sprung balance with silicon hairspring makes the movement resistant to magnetic fields up to 15,000 gauss. Through the sapphire caseback, you can see the arabesque Geneva waves on the bridges and rotor.

How It Compares

Green dials polarize opinions more than black or blue. Some buyers find them versatile enough for daily wear while others see them as a second-watch addition. On the Seamaster, the green reads dark enough to pass as nearly black in low light, which makes it more adaptable than brighter green options from other brands. The steel bracelet grounds the watch in a tool-watch context rather than a fashion statement. This replica Seamaster 210304 green offers a way into the Diver 300M lineup for buyers who already own a black or blue dive watch and want a different angle.
