$5,645.00 USD
OMEGA Seamaster 300 Master Co-Axial Ref. 233.30.41.21.01.001 is a modern interpretation of the legendary Seamaster 300 originally introduced in 1957 for professional divers and underwater exploration. Combining heritage-inspired styling with advanced OMEGA engineering, this reference features a distinctive black dial, vintage-inspired luminous hour markers, a 41mm stainless steel case, and matching black ceramic dive bezel. Its clean proportions and unmistakable tool-watch character make it equally compelling as a capable dive watch or an everyday luxury sports watch.
At its heart is the exceptional OMEGA Master Co-Axial Calibre 8400 automatic movement. Developed to deliver outstanding precision, reliability, and resistance to magnetic fields exceeding 15,000 gauss, the Calibre 8400 incorporates OMEGA's Co-Axial escapement, silicon balance spring, and twin barrels mounted in series. Offering approximately 60 hours of power reserve, the movement is visible through the sapphire crystal caseback and represents an important generation of OMEGA's advanced anti-magnetic mechanical watchmaking.
