About this watch

When it comes to luxury watches, few names resonate as strongly as Omega. Known for their precision, style, and innovation, Omega has been setting the pace in the horology world for decades. The Omega Seamaster PloProf is not just a watch; it’s a statement. Originally designed for professional divers, this timepiece blends functionality with luxury in a way that is hard to match. With its rugged titanium construction, impressive water resistance, and state-of-the-art movement, the PloProf is engineered for those who demand the best. At the heart of the PloProf lies the Omega caliber 8912. This automatic movement features a Co-Axial escapement, which reduces friction and enhances accuracy. With 38 jewels and a power reserve of 60 hours, this movement is a testament to Omega's commitment to precision. The use of titanium in the construction of the Seamaster PloProf is a game changer. Not only is titanium lightweight, but it’s also incredibly strong and resistant to corrosion. This makes it perfect for a diving watch that might see its fair share of saltwater adventures! With a diameter of 55 mm, the PloProf is not for the faint-hearted. Its size is imposing, but it’s designed to be functional. The black dial with stick and dot indexes offers excellent legibility even in low-light conditions, making it a perfect companion for underwater adventures. The rotating bezel, marked from 0-60, is essential for divers to track their time underwater. It’s intuitive and easy to manipulate, ensuring that even in the most challenging conditions, you can keep an eye on your dive time. One of the standout features of the PloProf is its sapphire glass. Known for its scratch resistance, sapphire ensures that your watch remains pristine, even after years of use.
