First introduced in 1957, this 18ct Rose Gold and Stainless Steel Omega Seamaster 300 automatic men's watch was originally designed especially for divers and professionals who worked underwater. Completely upgraded and enhanced for a new generation of pioneering spirits, this handsome watch is fastened with a luxurious brushed and polished stainless steel and 18ct Sedna rose gold bracelet, and features a 41mm brushed and polished stainless steel case finished with a unidirectional rotating 18ct Sedna rose gold bezel accentuated with a black ceramic and Ceragold diving scale. Beneath the domed scratch-resistant sapphire crystal with anti-reflective treatment inside, the sand-blasted black dial features angled baton and Arabic numeral hour markers coated with vintage Super-LumiNova and elegant 18ct Sedna rose gold hands. Water resistant to a remarkable 300m, the transparent caseback allows a glimpse of the anti-magnetic Omega Master Co-Axial Calibre 8400 automatic movement which beats at the heart of this remarkable timepiece. Completely upgraded to include Omega's most innovative technology and materials, this remarkable watch represents both the illustrious heritage and pioneering spirit of this iconic brand. 233.20.41.21.01.001
