The Omega Constellation is one of the most storied lines in Swiss watchmaking, introduced in 1952 as a symbol of chronometric precision and refined elegance. Over seven decades the collection has evolved from slim dress watches into the architecturally bold, integrated-bracelet designs recognized today, always anchored by Omega's commitment to accuracy and luxurious finishing. Reference 123.55.31.20.55.002 represents the collection at its most opulent, pairing precious materials with Omega's hallmark Co-Axial technology in a 31mm format sized ideally for a broad range of wrists.

The 31mm yellow gold case gives this Constellation a warm, radiant presence that few competing references can match at this size. Yellow gold is a classic choice that evokes the original spirit of the Constellation line while lending the watch an undeniable sense of richness and longevity — gold does not corrode, tarnish, or fade, making it as practical a luxury choice as it is a beautiful one. The polished and brushed surfaces of the case interact with light in the refined, multi-finish manner that Omega's craftspeople have long mastered.

The white mother-of-pearl diamond dial is the centrepiece of this reference's visual story. Mother-of-pearl is a natural material, meaning no two dials are precisely identical; its iridescent surface shifts subtly under changing light, giving the watch an organic, living quality that printed or lacquered dials cannot replicate. The addition of diamond hour markers elevates the dial further, scattering light across the wrist and reinforcing the watch's position as fine jewelry as much as precision timepiece.

Framing that extraordinary dial is a diamond-set bezel, one of the Constellation's most recognizable design signatures in its jeweled form. The diamonds are set with the rigorous quality control that Omega applies across its precious-stone offerings, ensuring consistent brilliance and secure setting for years of wear. The yellow gold integrated bracelet flows seamlessly from the case in the manner that defines the modern Constellation silhouette, creating a unified, sculpted look on the wrist rather than the watch-and-bracelet separation of more traditional designs. Powering this watch is Omega's Co-Axial movement, a technology that uses a three-level escapement to reduce friction between components, resulting in improved long-term accuracy and extended service intervals compared with conventional lever escapements — a meaningful benefit hidden beneath all that glamour.

Buying this reference from Bizak & Co. means acquiring a brand-new example of one of Omega's most desirable precious-metal Constellations from a trusted luxury watch specialist. At Bizak & Co. we are committed to offering the best price on authentic, new Omega timepieces, and our team is available to answer every question you have before and after your purchase. Reach out today to secure reference 123.55.31.20.55.002 and experience the Omega Constellation Co-Axial in yellow gold for yourself.

FAQ

1. What makes the Omega Constellation 123.55.31.20.55.002 special?
Reference 123.55.31.20.55.002 combines a solid yellow gold case and bracelet with a white mother-of-pearl diamond dial and a diamond-set bezel, placing it among the most luxurious expressions in the Constellation lineup. The integrated yellow gold bracelet and the natural iridescence of the mother-of-pearl dial give it a jewelry-grade presence that is rare at any price point. It is offered here brand new, ensuring factory-fresh condition and full manufacturer quality.

2. What movement powers the Omega Constellation Co-Axial 31mm?
This watch is equipped with an Omega Co-Axial movement, a technology developed with watchmaker George Daniels and adopted by Omega to reduce escapement friction and improve long-term accuracy. The Co-Axial escapement also extends the intervals between required servicing compared with a standard lever escapement. The exact caliber designation is not specified in the available product information, so we recommend confirming details directly with Bizak & Co.

3. What is the case size of reference 123.55.31.20.55.002?
The case measures 31mm in diameter, a refined and versatile size that sits elegantly on a wide range of wrists. The 31mm format is a classic choice within the Constellation collection for those who prefer a more understated, feminine proportion without sacrificing visual impact. The yellow gold construction adds perceived presence beyond what the diameter alone would suggest.

4. Is the Omega Constellation 123.55.31.20.55.002 suitable for everyday wear?
The Omega Constellation is designed to be a wearable luxury watch, and yellow gold combined with Co-Axial precision makes this reference both beautiful and practically reliable day to day. That said, its diamond bezel, diamond dial, and full yellow gold construction mean most owners treat it as a dress or occasion watch rather than an everyday sports piece. Its suitability depends on your lifestyle and how you prefer to use a precious-metal timepiece.

5. What are the dial and material details of this Constellation?
The dial is crafted from white mother-of-pearl, a natural shell material prized for its shifting iridescence, and is set with diamond hour markers for additional brilliance. The case and bracelet are both made from yellow gold, giving the watch a fully precious-metal construction from lug to clasp. The bezel is also diamond-set, completing an all-luxury material palette throughout.

6. How can I buy the Omega Constellation 123.55.31.20.55.002 from Bizak & Co.?
