Description
This replica Constellation 131304 blue introduces a striking blue aventurine dial to the Constellation’s updated 41mm case architecture. The 131.30.41.21.99.003 reference uses a dial surface embedded with metallic particles that shimmer under light, producing an effect closer to a starfield than a standard sunburst finish. At 41mm this sits at the larger end of the Constellation size range, built for wearers who prefer their dress watches with a bit more visual authority. The stainless steel case and bracelet ground the adventurous dial choice in practical daily-wear territory.

The 131-series case represents the Constellation’s current generation. Thinner bezels and longer lugs distinguish it from the older 123-series references, and the date window moves to 6 o’clock for symmetry.
Inside the Movement
Omega equipped the genuine 131.30 references with the Master Chronometer caliber, and this version follows the same automatic architecture with center seconds and date. The 41mm case provides adequate depth for the movement while keeping thickness reasonable on the wrist. The aventurine dial technology is worth understanding: rather than painted or printed pigment, the metallic flecks are suspended within the glass substrate itself. This means the shimmer effect changes with every angle and light source. The rose gold 123.25 in 38mm takes the opposite approach with a traditional warm-metal finish. Both belong to the Constellation catalog, but the aventurine dial on the 131.30 is genuinely unusual in the lineup.
What Sets It Apart
Blue aventurine dials appear across several luxury watch brands, but Omega’s implementation on the Constellation 131.30 stands out because the 41mm case and integrated steel bracelet frame the dial with clean, angular lines. The result is a dress watch that works at formal events and a conversation starter on casual days. For anyone drawn to the 38mm Constellation models but wanting more wrist coverage, this replica Constellation 131304 blue delivers the same refined DNA at a larger diameter.
