This replica seamaster 210224 wears the 210.22.42.20.03.001 reference and pairs a two-tone steel-and-gold case with a blue dial in the 42mm Diver 300M format. The 210.22 prefix indicates the two-tone Sedna gold combination, where rose-gold-toned accents appear on the bezel, crown, and bracelet center links against a steel foundation. Omega uses its proprietary Sedna gold alloy across the Seamaster range to deliver warm rose tones that resist fading over time.

Technical Overview

• Reference: 210.22.42.20.03.001
• Case diameter: 42mm
• Case material: stainless steel with Sedna gold accents
• Bezel: ceramic with Sedna gold diving scale
• Dial: blue with wave pattern
• Crystal: domed sapphire
• Bracelet: two-tone steel and Sedna gold
• Movement: automatic with date
• Water resistance: 300 meters

The Ceragold bezel technology bonds gold directly into the ceramic insert, ensuring the diving numerals are flush and resistant to wear. This process differs from standard printed or filled bezels by making the gold an integral part of the ceramic structure.

Inside the Movement

The automatic caliber follows the same specification as the standard steel Diver 300M, delivering date function and daily-wear reliability. Through the exhibition caseback, the movement finishing matches what the rest of the Seamaster 300M line offers, with a decorated rotor and striped bridges. Where this reference diverges is entirely on the exterior. The blue wave dial paired with Sedna gold indices creates a color combination that reads warmer and more luxurious than the monochrome steel variants. For a full-steel alternative, compare against the Planet Ocean 600M 215.20.46, which trades the two-tone look for a larger case and higher depth rating. Both are available in the Seamaster range.

What Sets It Apart

Two-tone dive watches occupy a niche that pure steel and pure gold models cannot reach. The steel provides structural rigidity and keeps weight manageable, while the Sedna gold accents add visual warmth without the heft or cost of a full-gold case. The blue dial amplifies this combination by providing a cool backdrop that makes the warm gold markers pop with contrast. On a bracelet, the alternating steel and gold links create a striped pattern down the wrist that catches light in alternating bands. This replica seamaster 210224 brings that two-tone Diver 300M aesthetic together in a balanced combination of materials and colors.
