522.50.45.52.03.001
The dial, in blue aventurine “Grand Feu” enamel, features an inner bezel and subdials in 18K Sedna™ Gold “exclusive acoustic waves”. The hour markers and hour/minutes hands are in diamond-polished 18K Sedna™ Gold. Providing extra touches of colour on the display are red tipped dial hands and blue CVD subdial hands.
The chime pusher at 8 o’clock sports a charming polished and embossed music note, while the split-seconds pusher at 2 o’clock has a red hybrid ceramic ring to mirror the look of the split seconds hand. Completing the look is a bracelet and buckle in 18K Sedna™ Gold.
The watch’s special presentation box in walnut features a resonance plate made of spruce to amplify the sound of each chime. The monumental case includes a magnifying glass to explore the watch’s details, a storybook and travel bag.
Providing the power is the most complicated calibre OMEGA has ever made: OMEGA’s Co-Axial Master Chronometer Calibre 1932. A fully integrated chronograph and minute repeater, which fuses both functions together in one watch movement, in order to chime the elapsed time.
