Details & Specifications
Description:
The Omega Seamaster Aqua Terra Railmaster XXL Chronometer reference 2806.52.37 is a bold, oversized homage to Omega's original 1957 Railmaster, built to withstand strong magnetic fields for railway and factory workers of the era. Housed in an imposing 49mm stainless steel case, the black dial is set with luminous Arabic numerals and stick hour markers, along with a small seconds sub-dial at 6 o'clock. Powered by the hand-wound Calibre 2201, this COSC-certified chronometer offers a generous 53-hour power reserve, while a transparent sapphire case back reveals the movement's finishing. Fitted with a brown leather strap on a steel folding buckle, the Railmaster XXL is a rare, statement-making piece from Omega's Seamaster line.
