Omega Seamaster Planet Ocean 600M Co-Axial 42 Stainless Steel / White / Rubber

About this watch

The Omega Seamaster Planet Ocean 600M Co-Axial 42 is not just a watch; it's a statement of luxury and sophistication. Founded in 1848, Omega has carved a name for itself as a leader in luxury watchmaking. The Seamaster collection has been synonymous with ocean exploration since its launch in 1948. This timepiece, with the reference number 232.32.42.21.04.001, is a part of the esteemed Seamaster Planet Ocean family. At the heart of this watch is the Omega caliber 8500 movement, an automatic marvel of engineering featuring a Co-Axial escapement that enhances precision and reduces friction. The rotating bezel is designed for diving, with a clear 0-60 scale that's easy to read under water or on land. With an impressive water resistance rating of 600 meters (or 2000 feet), this watch is a true diving companion. The striking white dial with mixed indexes gives it a distinct look, and the round shape and 42 mm diameter make it suitable for various wrist sizes.
