Omega Seamaster Professional Diver 300M Chronograph | 41.5mm I Ref. 2594.52

The Omega Seamaster Professional Diver 300M Ref. 2594.52 is a robust neo-vintage sports chronograph combining Omega’s professional dive-watch design with a capable column-wheel chronograph movement. It features a 41.5mm stainless steel case, black unidirectional diving bezel, sapphire crystal, helium escape valve, and matching stainless steel bracelet.

The black dial features luminous hour markers and hands, three chronograph registers, and a date window at 3 o’clock. Subtle red chronograph accents add contrast while maintaining the technical, monochromatic appearance of the watch. Its screw-down crown and 300-meter original water-resistance rating give it the functionality expected from the Seamaster Professional line.

Condition

Please review the photos carefully for an accurate representation. Light scratches, bracelet wear, bezel wear, crystal wear, or other signs of use consistent with age may be present and do not affect functionality. The watch presents well overall with expected wear for its age.
