OMEGA 123.10.31.20.55.001 CONSTELLATION CO-AXIAL 31mm STEEL - BRAND NEW

The Omega Constellation is one of the most storied lines in Swiss watchmaking, introduced in 1952 to celebrate Omega's chronometric achievements in official observatory trials. Over the decades the Constellation has evolved from its distinctive pie-pan dials of the 1950s into the sleek, integrated-bracelet icon it is today — a watch that balances technical credentials with undeniable elegance and has graced the wrists of style icons and discerning collectors worldwide.

Reference 123.10.31.20.55.001 represents the Constellation at its most refined. The 31mm stainless steel case is sized with intention, offering a versatile fit that transitions seamlessly from a business setting to an evening occasion. The integrated stainless steel bracelet flows from the lugs with the signature Constellation grace, providing a polished, unified aesthetic that feels both contemporary and timeless on the wrist.

The dial is the undisputed centerpiece of this reference. A white mother of pearl surface catches and refracts light with an organic iridescence that no painted or lacquered dial can replicate — each example is subtly unique by nature. Diamond hour markers punctuate the dial with restrained luxury, catching the light and adding a layer of brilliance without overwhelming the delicate, pearlescent canvas beneath them. The stainless steel bezel frames the dial cleanly, allowing it to command full attention.

Powering this Constellation is Omega's Co-Axial escapement, an engineering milestone that co-founder George Daniels conceived and that Omega brought to series production — a genuine horological achievement. The Co-Axial mechanism significantly reduces sliding friction within the escapement, contributing to greater long-term accuracy and extended service intervals compared with traditional lever escapements. It is a movement philosophy that speaks to buyers who want their watch to perform as impressively as it looks.

For collectors and first-time luxury watch buyers alike, the Omega Constellation 123.10.31.20.55.001 represents outstanding value: a brand-new example of an iconic Swiss line combining a precious mother of pearl diamond dial, Co-Axial precision, and the enduring prestige of the Constellation name.
