The Seamaster Professional Diver 300M was created in 1993. Since then, it has constantly been evolving with the best innovation and pioneering technology to become one of the most authentic ocean timepieces in the watchmaking world. The legendary dive watch is available in a range of sizes, from 41 mm to 44 mm and offers classic dial colours such as black, blue and white. The water‑resistant collection is also notable for its unique range of materials, including stainless steel, 18K gold and ceramic, giving each watch its own unique strength, quality and style. Whether you choose between the standard versions or the chronograph models, some of the most iconic features of the Diver 300M design include the helium escape value, the diving bezel, and the waved dial, which evokes the spirit of the sea and incorporates OMEGA’s very best laser‑engraving technology. You can also choose to wear the wristwatch on a metal bracelet, rubber strap or NATO strap. Finally, it’s important to note that the timepieces and movements in today’s Seamaster Diver 300M collection are all Master Chronometer certified, giving you a standard of precision, chronometric performance and magnetic‑resistance that is the highest in the Swiss watch industry.
