Pre-owned Omega Seamaster Chronograph ref. 2599.80.00 takes everything collectors love about the iconic Seamaster Professional 300M and adds the functionality of a mechanical chronograph. It features all of the collection’s signature design elements, including the blue wave-pattern dial, skeletonized hands, scalloped dive bezel, distinctive five-row bracelet, and Omega’s elegant twisted lyre lugs. While the additional chronograph registers create a busier dial than the standard three-hand model, they do little to detract from the Seamaster’s unmistakable identity. The 41.5mm stainless steel case is paired with a domed, anti-reflective sapphire crystal and has 300 meters of water resistance, making it every bit as capable as it is stylish. Powering the watch is Omega’s self-winding caliber 1164 with a 44-hour power reserve. Shop OMEGA Seamaster Collection
