Seamaster Planet Ocean / Older Aqua Terra (231)
The Omega Seamaster Planet Ocean and older Aqua Terra references, including the 231 series, showcase Omega’s evolution in modern luxury sports watchmaking. The Planet Ocean line delivers professional-grade diving performance with robust construction, bold bezels, and 600m water resistance, while early Aqua Terra models offer a more refined, versatile aesthetic inspired by maritime heritage. Both are powered by reliable Omega Co-Axial automatic movements, ensuring precision and durability. The 231 references sit within a transitional era of Seamaster design, blending tool-watch capability with elegant styling, making them attractive to collectors who appreciate early modern Omega innovation.
