Not exactly gold
Omega has wisely not messed with a good thing by keeping all the important design elements in place from the last 007 Edition Seamaster and updating materials, textures, and colors on subsequent releases. The new Bronze Gold references–there are two, based on the strap–are the most impressive since the last Bond watch.
Omega developed the alloy used here by blending 37.5 percent gold with mostly bronze and a bit of silver and palladium for stability. The amount of gold included is technically enough to call the watch 18-karat gold, but the appearance is distinctly different.
It has an aged tone but not a faux patina. The brushed finish still looks pristine, with a luster that is more like polished bronze. According the brand, it will retain that finish with minimal effort.
Omega’s new alloy also boasts enhanced durability. The precious metals prevent corrosion that commonly plagues bronze, and the bronze strengthens the gold by fending off scratches and discoloration.
