If you're searching for an authentic 1950s jumbo Omega watch, your quest ends here! This timepiece boasts a substantial 38.4mm diameter, dwarfing the average classic Seamaster of approximately 34mm (excluding the crown).


The dial exudes a gorgeous copper/gold patina, accentuated by gold hands, applied gold hour markers, and Arabic numerals at 3, 9, and 12. The gold Omega logo is also present, with "Omega" printed in black below it. Positioned at 6, the small seconds sunken sub-dial features a circular Guilloche finish.


The stainless steel case and case back exhibit a polished appearance, devoid of any major scratches or dents. The Omega reference 2505-18 is fully marked inside the case back, with the crown likely being original but unmarked.


Powered by the Omega calibre 265, an in-house production and a derivative of the 30T2, the watch is backed by the legacy of movements that significantly contributed to Omega's success over 25 years.


The watch comes with a new non-Omega brown strap.
