Pre-owned Omega Seamaster Diver 300M ref 212.30.44.50.03.001 (2014) brings added complexity to one of Omega’s most recognizable dive watch platforms. This is the chronograph-equipped Diver 300M, built in a substantial 44mm stainless steel case that still feels purposeful rather than oversized. The lacquered blue dial embraces the Seamaster’s maritime identity, laid out in a classic tri-compax format with chronograph registers at 3 and 6 o’clock and small seconds at 9. A polished blue ceramic unidirectional bezel frames the dial, reinforcing the watch’s professional dive credentials. Details like the helium escape valve and the integrated date corrector at 10 o’clock underline its tool-watch roots, while the stainless steel bracelet keeps things balanced for everyday wear. Inside, the Co-Axial caliber 3330 powers the chronograph, offering modern Omega reliability with smooth operation. Shop OMEGA Seamaster Collection
