OMEGA Seamaster Planet Ocean Worldtimer Black Ceramic
The OMEGA Seamaster Planet Ocean Worldtimer Black Ceramic marks a major milestone for the brand, becoming the first professional 600-metre dive watch equipped with a world-time complication. Designed for travellers, explorers and professional divers alike, it combines advanced materials, exceptional magnetic resistance and high-precision timekeeping in a lightweight yet durable construction.
Crafted entirely in black zirconia ceramic (ZrO₂), the 45.5 mm case keeps the total weight at only 143 g, offering impressive comfort despite its large presence. This ultra-resistant ceramic ensures outstanding scratch resistance and structural stability, making it ideal for long-distance diving or cross-time-zone missions.
Worldtimer Functionality
The dial features a 24-city outer ring representing global time zones, including major destinations such as New York, Tokyo, Paris and Geneva. At 6 o’clock sits a discreet date display. The honeycomb-textured hour ring adds depth while improving legibility.
At the centre lies a stunning Grade 5 titanium plate, laser-ablated to create a topographic map of the Northern Hemisphere as seen from the North Pole. The oceans are finished in turquoise or grey lacquer, while the surrounding 24-hour ring provides a colour-coded day/night indication, enhancing readability for frequent travellers.
Calibre 8938 – METAS Master Chronometer
Inside the watch beats the METAS-certified calibre 8938, an automatic movement operating at 25,200 vph. Its twin mainspring barrels deliver a robust 60-hour power reserve. Equipped with a silicon hairspring and anti-magnetic components, it withstands magnetic fields up to 15,000 gauss. The sapphire case-back reveals the decorated movement, complete with OMEGA’s signature Arabesque Geneva waves.
Diving Performance
The watch maintains its full professional diver capabilities, featuring:
• 600 m / 2000 ft water resistance
• Black ceramic unidirectional bezel with laser-engraved diving scale
• Helium escape valve
• Robust rubber strap with matching ceramic clasp
Despite its world-time complexity, the watch remains a true member of the Planet Ocean family—built for deep-sea performance as much as for international travel.
