About this watch

The Omega Seamaster Diver 300M Nekton Edition is a masterpiece of horology that embodies precision, style, and durability. Crafted from a combination of ceramic and stainless steel, this timepiece exudes a sense of modernity while remaining elegant. The black ceramic bezel with a rotating dive scale is not only visually appealing but also functional, allowing divers to track their underwater time effectively. With its impressive 300m water resistance, this watch is perfect for both casual and formal settings. At the heart of the Nekton Edition lies the Omega caliber 8800, a self-winding movement that boasts an extraordinary Co-Axial escapement, a 55-hour power reserve, and a frequency of 25,200 vibrations per hour. The Master Chronometer certification approved by METAS ensures accuracy and resistance to magnetic fields reaching up to 15,000 gauss. The rhodium-plated finish with Geneva waves in arabesque adds a touch of elegance, while the intricate detailing of the movement can be admired through the transparent case back. With its exceptional design, robust functionality, and commitment to quality, this watch is an investment that combines style, functionality, and durability.
