Pre-owned/unworn Omega Seamaster Planet Ocean 600M ref 215.32.46.51.09.001 (2026). The Planet Ocean collection has always represented the more modern and experimental side of Omega’s dive watch lineup, and this reference pushes that identity even further with one of the most distinctive color palettes the series has seen in recent years. While earlier Planet Ocean models usually have black-and-orange tool-watch aesthetics, this version introduces warmer beige and bronze-inspired tones that give the watch a noticeably different personality without losing the collection’s aggressive, professional dive-watch DNA. The 45.5mm stainless steel case is paired with brushed silicon nitride ceramic bezel and chronograph pusher accents finished in a rich bronze color, creating a striking contrast against the sandblasted beige dial and matching rubber strap. Omega also adds “azure” bronze ceramic subdials and grey PVD hands and markers, giving the watch a layered, almost industrial appearance that feels highly contemporary on the wrist.
