Omega Unveils the Forth Generation of Iconic Seamaster Planet Ocean, Ushering Bold Updates

Published: 18 Nov 2025
On its 20th anniversary, the Omega Seamaster Planet Ocean lineup, a cornerstone of horological heritage since 1932, has emerged from a comprehensive overhaul to reveal the brand's fourth-generation design.

The newly presented Planet Ocean lineup by Omega marks a significant leap forward from the original 1964-1970s-inspired Seamaster designs. This remodel is sportier than Aqua Terra and stronger than the Diver 300M collections, etching an exclusive place for itself in Omega’s storied legacy. The introduction of angular-designed cases that measure 42mm by 13.79mm, paired with the infusion of flat sapphire crystal and a titanium caseback, breaks through what was previously seen in the 16.1mm thickness of the third generation. The refreshed design also incorporates a more abrupt truncation, where the case meets the bracelet or rubber strap, presenting a crisp finish to the silhouette of the watch. Indices, infused with Super-LumiNova X1, hands, bezel pip, the Omega name and logo, and the Arabic numerals - every facet in the new line of watches is meticulously detailed. The watches encompass stainless steel cases, exhibiting an inner titanium ring capped with matte black dials that display either white or matte orange varnished or rhodium-plated Arabic numerals. These innovatively redesigned watches are powered by the Co-Axial Master Chronometer Calibre 8912, offering bi-directional and automatic winding. An additional Silicon ‘Si14’ balance spring aids the free-sprung balance. Coupled with a Co-Axial Escapement and a pair series-mounted barrels, the timepiece offers an elevated 60-hour power reserve. The modified aesthetics are undeniably captivating. The case, although still bearing a faint lyre lug twist from former versions, is much sharper, with polished chamfers and brushed sides. The crown guard is meticulously added, while a second crown for manual helium release is completely eradicated. Even the flat link bracelet tying the design together is elegantly redesigned.
