About this watch

The Omega Seamaster 300 Master Co-Axial is a masterpiece of watchmaking that embodies the spirit of diving watches while offering modern technology and classic design. This timepiece, with its reference number 233.32.41.21.01.002, pays tribute to Omega's rich heritage in horology, blending tradition with innovation. The striking black dial offers clear visibility, even in low light conditions, thanks to stick and dot indexes and arrow hands that serve both functional and design purposes. With a diameter of 41.00 mm and a robust stainless steel case, this watch is built to withstand the rigors of daily wear, while its rotating bezel allows for precise time-tracking underwater. At the heart of the Seamaster 300 lies the Omega caliber 8400, an automatic movement featuring a self-winding mechanism with a Co-Axial escapement that ensures greater precision, stability, and durability. With a power reserve of up to 60 hours and resistance to magnetic fields greater than 15,000 gauss, this watch is a reliable companion for everyday wearers and professionals alike.
