To join the existing Breguet diamond and Tahitian mother-of-pearl Marine Haute Joaillerie , the watchmaker earlier this year added three other versions with white mother-of-pearl marquetry . Exquisite dials feature color-plays in sapphire-set blue , ruby-set red and emerald-set green . Breguet re-designed the curved based on the dominant color of each version ( red , green or blue ). Breguet depicts the plant ’ s arabesques on the Marine Haute Joaillerie Poseidonia through the art of mother-of-pearl marquetry and invisible gem setting , while the reverse view shows that a mechanical movement can also be dressed as an elegant engine with a mother of pearl rotor studded with diamonds on the outer perimeter .
Prices : $ 256,000 for the ruby or sapphire versions , $ 276,000 for the diamond and emerald versions
