Description

The classic 45.5 mm numbered edition Chrono Chime has an 18K Sedna™ Gold case inspired by the 2nd generation Speedmaster, the CK 2998, the first watch worn in space.

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.

The advantages
of this watch

Behind the elegance of every Master Chronometer timepiece is the highest level of testing: 8 tests over 10 days, to ensure superior precision and anti‑magnetic resistance. We’ve raised our standards. You can too.

Master Chronometer Certified

Superior Precision

Twice as precise as any officially certified chronometer

Our Master Chronometer watches are tested and certified twice. Firstly, the movement is tested by the Official Swiss Chronometer Control (COSC) with precision criteria of 0/+5 seconds per day. Then the complete watch and its movement undergo eight Master Chronometer tests set by the Swiss Federal Institute of Metrology (METAS) with criteria of %3/%4 seconds per day.

Master Chronometer Certified

Anti-magnetic

Proprietary anti-magnetic materials

Everyday items such as mobile phones, metal clasps on handbags, laptops, MRI, induction hobs or automatic doors; subject a watch to magnetic fields and can affect its performance for good. To prevent the risk of permanent deviations of up to several minutes a day we've conceived movements with antimagnetic materials, such as the silicone balance spring, capable of withstanding the highest fields.

Water-resistance

To ensure the integrity of our timepieces at depth, not just some but all watches are fully immersed in water and pressure is applied up to the point of the guaranteed water resistance. By submerging each watch in water we have chosen – yet again - to exceed normal testing standards.

Durability

Our watches are engineered to the highest standards and certified as such. Each watch destined to become a Master Chronometer must first pass 8 stringent tests. The examinations we perform for precision, magnetic-resistance, power reserve and water-resistance allow us to cover the certified watches with a comprehensive 5-year warranty.

Less servicing

Extended service intervals

Each Master Chronometer is equipped with a Co-Axial escapement, conceived to reduce the mechanical constraints inside the movement. This significantly reduces the need for lubrication and hence the need for servicing. All mechanical movements need to be serviced periodically, but an OMEGA Master Chronometer offers more time between servicing than many other watches.
6 / 6

Shock-resistance

A selection of test watches face shock-resistance examinations that are equivalent to 5,000 g (1 g is equal to the force of gravity at the Earth's surface) to ensure our complex mechanical mechanisms are also extraordinarily robust. Not just for everyday use but for active sports such as golf and sailing.

Key materials

Sedna^TM Gold
Sapphire Crystal

1 / 2

Sedna^TM Gold

OMEGA has been using the exclusive 18K Sedna^TM Gold, its own fiery rose gold alloy, since 2012. Named after Sedna, an orbiting planetoid that has been described as one of the reddest in the solar system, Sedna^TM Gold not only bears all the standard characteristics of other 18K golds, but it also offers high resistance to the fading of colour and lustre over time. Its unique composition includes copper and palladium for colour and stability.
2 / 2

Sapphire Crystal

To really appreciate the finer details of a timepiece, OMEGA uses synthetic sapphire crystal with a highly scratch-resistant and anti-reflective treatment. Before the machining and finishing processes take place, the sapphire crystals are produced under the Verneuil process, also called flame fusion. It involves the melting of the raw substance using oxyhydrogen flame and the crystallisation of the melted droplets to form a cylinder. Graded 9 on the Mohs-hardness scale (graded 1-10), the resulting sapphire crystals are virtually scratch-proof and very hard, ensuring an unhindered vision at all times.

Movement CALIBRE OMEGA 1932

The most complicated movement the brand has ever produced, OMEGA’s Co-Axial Master Chronometer Calibre 1932, developed with Blancpain, is a fully integrated chronograph and minute repeater. In order to chime the elpased time, the 1932 requires its own mechanical “brain” to merge the two functions and sense which one to engage. Its Co-Axial escapement, an essential component in all of OMEGA’s movements, beats at an unusual 5 Hz to display 1/10th of a second, like the pocket chronographs used to time the 1932 Olympic Games. The complex movement also integrates a security and split seconds function. The luxurious handmade calibre is satin-brushed, mirror polished and graced with 46.44 grams of gold.
