About this watch

The Omega Seamaster 300 Master Co-Axial Platinum is a true icon in the world of luxury watches, blending elegance with high performance. This stunning timepiece features a rich heritage dating back to 1948, with the Seamaster 300 specifically being a classic diver's watch that has stood the test of time. The platinum case elevates its status significantly, not only looking incredible but also resistant to corrosion. The blue dial encased in a lustrous platinum shell is both a statement piece and comfortable wear. With water resistance up to 300 meters, this watch is a reliable companion for underwater adventures. At the heart of this watch is the Omega caliber 8401, a self-winding movement that offers greater precision, stability, and durability through its Co-Axial escapement. The platinum bracelet feels as good as it looks, fitting snugly on the wrist with an adjustable clasp. This watch's versatility makes it suitable for various occasions, from business meetings to diving into the ocean. Its limited availability due to being a limited edition adds to its value and exclusivity.
