Historical significance
- Science Museum Group catalogues object 1975-13 as “Omega Megaquartz 2400 marine chronometer, 1950-1976”. The exact photograph shows a wristwatch with bracelet, not a boxed shipboard chronometer.
- “Marine Chronometer” is retained as part of the museum title, but the object is classified here as a wristwatch. The name alone is not evidence of naval issue or use aboard a ship.
- The museum lists stainless steel, brass and glass. Its published dimensions distinguish overall measurement from the object as displayed; no oscillator frequency, trial certificate or service history is asserted here.
- Current operation, service history and public display have not been verified. Catalogue dimensions describe the museum object, not measurements taken from the photograph.
