Presented on a blue rubber strap, the pre-owned 42mm Seamaster 200m Co-Axial Master Chronometer exudes a blend of stainless steel and 18K Sedna gold. This Omega features a blue ceramic bezel with a Ceragold diving scale, infusing both elegance and practicality. At its heart lies the OMEGA Master Chronometer Calibre 8800, visible through the sapphire-crystal caseback with a wave-edged design.
