This replica Seamaster 210204 blue 44mm carries reference 210.20.44.51.03.001 and pairs the Diver 300M chronograph case with a blue ceramic dial and rubber strap. The 44mm steel case features rose gold accents on the bezel, crown, and chronograph pushers, while the rubber strap replaces the standard bracelet for a sportier, lighter configuration. Omega designed this combination specifically for active wear, where the rubber strap handles moisture and movement better than metal links.

Case & Movement Specs

• Case diameter: 44mm
• Case material: steel with rose gold accents

The rubber strap drops the overall weight compared to the bracelet version, making the 44mm case feel less imposing during extended wear. The deployant buckle in matching two-tone finish ties the strap back to the case aesthetically.

Caliber Breakdown

Where the bracelet version of this reference leans dressy, the rubber strap shifts the entire personality toward active use. The strap material resists salt water, UV exposure, and sweat without degradation, which makes it the practical choice for anyone who actually wears their Seamaster in the water. The blue ceramic wave dial matches the strap color closely, creating a monochrome blue effect that the steel bracelet version cannot achieve. For a chronograph in full black instead, see the blue Seamaster 210304 chronograph on steel. The broader Seamaster collection offers both strap and bracelet options across most references for exactly this kind of personalization.

How It Compares

Rubber-strap Seamaster chronographs occupy a specific lane within the lineup. They appeal to buyers who want the complication set and the two-tone dress code but prefer a lighter, more flexible wearing experience. The rose gold pushers and bezel numerals provide enough metal contrast against the blue rubber to keep the watch from looking purely utilitarian. On warm days or during sport, the strap breathes where a bracelet would stick. This replica Seamaster 210204 blue 44mm on rubber gives you the full chronograph specification with a wearing experience that favors comfort over formality.
