To address the threat of magnetic fields, the Omega Seamaster 15'000 Gauss (ref: 231.10.42.21.01.002) utilizes non-ferrous movement components rather than a traditional Faraday cage. This innovation allows the watch to withstand magnetic fields exceeding 15,000 gauss while maintaining COSC-certified chronometric precision, all visible through a transparent caseback.
