About this watch

The Omega Seamaster Planet Ocean Ultra Deep O-Megasteel is a testament to Omega's innovation and dedication to excellence. This watch combines advanced technology with a striking design that is hard to resist. At the heart of this watch lies the Omega caliber 8912, an automatic movement that boasts features like a frequency of 25,200 vibrations per hour and a power reserve of 60 hours. The watch has a robust presence on the wrist, with a diameter of 45.50 mm and a height of 18.12 mm, and is made from high-quality materials like titanium, ceramic, and stainless steel. The stunning blue gradient finish is reminiscent of the deep ocean, making it not just a watch but a work of art. One of the standout features of the Ultra Deep is its impressive water resistance, with a staggering 6000 meters (or 20,000 feet) of water resistance, making it built for the serious diver. The watch also features a rotating bezel with a scale from 0-60, designed specifically for diving, and is protected by a sapphire crystal that adds an extra layer of protection. Wearing the Seamaster Planet Ocean Ultra Deep is an experience in itself, with a comfortable rubber strap and arrow-shaped hands that glow in the dark.
