About this watch

The Omega Seamaster Diver 300M Master Co-Axial 42 Sedna Gold / Blue / Rubber is a masterpiece of luxury watchmaking, boasting a stunning design that effortlessly transitions from formal to casual wear. At its core lies the Omega caliber 8801 movement, a self-winding marvel certified by METAS for accuracy and performance. With a power reserve of 55 hours, this watch is resistant to magnetic fields up to 15,000 gauss and features automatic winding in both directions. The free-sprung balance ensures excellent stability and accuracy, making it a reliable companion for any adventure. The Sedna gold case adds a touch of luxury, while the blue ceramic bezel provides scratch-resistance and durability. The dial is designed for readability, featuring stick and dot indexes with sword-shaped hands. A date function at 6 o'clock adds to its practicality without overshadowing its elegant design. The watch feels substantial yet comfortable on the wrist, thanks to its rubber strap that's both breathable and adjustable.
