About this watch

The Omega Seamaster Diver 300M Master Co-Axial 44 Chronograph is a masterpiece of design and engineering. This stunning timepiece seamlessly blends style, functionality, and Swiss craftsmanship, making it perfect for both diving enthusiasts and watch collectors alike. The deep black ceramic face features luminous stick and dot indexes, ensuring easy readability in low-light conditions. The sword-shaped hands glide smoothly over the face, providing a sense of fluidity and elegance that is hard to replicate. Crafted from high-quality stainless steel, the case is robust yet stylish, striking a perfect balance between presence and wearability. At the heart of the Seamaster Diver 300M lies the Omega caliber 9900, a marvel of horological engineering certified by METAS for precision and resistance to magnetic fields up to 15,000 gauss. This watch boasts an impressive water resistance of up to 300 meters, making it perfect for swimming, snorkeling, or diving. The helium escape valve ensures you can take it to deeper depths without worrying about damage. The chronograph function allows for precise timing, and the pushers are intuitively placed. Omega has a reputation for using premium materials, and this watch is no exception, with a scratch-resistant ceramic bezel and sapphire crystal protecting the dial from everyday wear and tear.
