Omega

Established in 1848, Omega has played a pivotal role in the history of watchmaking, from timing the Olympics to being the first watch on the moon. Their innovations include the Co-Axial escapement and Master Chronometer certification, setting new standards for precision and magnetic resistance. The brand's iconic collections include the Speedmaster, first worn on the moon, the Seamaster, trusted by professional divers and James Bond, and the elegant Constellation line. Each timepiece demonstrates their commitment to pushing the boundaries of watchmaking technology while maintaining their heritage of precision and reliability.
