Unworn in like-new condition, this Omega Seamaster 300 Co-Axial Master Chronometer Ref. 234.30.41.21.03.002 comes complete with original box and papers, including warranty documents dated. A striking reinterpretation of Omega’s legendary dive watch heritage first established in 1957, the Seamaster 300 blends vintage inspiration with contemporary mechanical mastery. The robust 41 mm stainless steel case features a unidirectional blue ceramic bezel and a stunning gradient blue dial with Arabic numerals and luminous indices for optimal legibility in all light conditions. Driven by Omega’s in-house Calibre 8912 with Master Chronometer certification — tested by METAS for precision, performance and resistance to magnetic fields — this model offers up to 60 hours of power reserve and superior reliability both above and below the surface. With water resistance to 300 m and a durable stainless steel bracelet, the Seamaster 300 is equally at home on a deep dive or the wrist of the discerning everyday wearer.
