The Omega Constellation has been one of the most iconic women's dress watch collections in Swiss watchmaking since its debut in 1952, consistently representing Omega's commitment to precision, elegance, and innovation. Over the decades the Constellation has evolved from a simple time-only dress piece into a technically formidable collection, culminating in today's Co-Axial Master Chronometer generation — the highest standard of chronometric performance and anti-magnetic protection in Omega's modern lineup.

Reference 131.55.29.20.55.003 is crafted entirely in Moonshine Gold, Omega's proprietary 18-karat gold alloy engineered to maintain its warm, pale-yellow radiance longer than traditional yellow gold. The 29mm case is perfectly proportioned for the wrist it is designed to adorn, while the signature Constellation claws on the case back and the polished and brushed finishing across the integrated bracelet speak to decades of design DNA refined to a contemporary ideal.

The white diamond dial is one of the most desirable configurations in the entire Constellation 29mm range. Diamond hour markers catch light with every movement of the wrist, creating an interplay of brilliance against the white dial surface, while the Moonshine Gold bezel frames the whole composition with consistent, warm luster. The result is a watch that reads unmistakably as a luxury object even from across a room.

Powering this reference is Omega's Co-Axial Master Chronometer movement, certified by the Swiss Federal Institute of Metrology (METAS) to meet the strictest standards in the industry — including resistance to magnetic fields of 15,000 gauss. The Co-Axial escapement reduces friction and wear, contributing to long-term reliability and extended service intervals, while Master Chronometer certification guarantees exceptional rate accuracy verified across multiple positions and conditions. This level of movement technology, housed inside such an elegant case, is a defining characteristic of the modern Constellation.

Wearing reference 131.55.29.20.55.003 is an experience defined by cohesion: the Moonshine Gold case flows seamlessly into the bracelet, the diamond markers punctuate the white dial with quiet luxury, and the 29mm footprint sits with understated authority on the wrist. Whether paired with eveningwear or elevated daytime attire, this Constellation commands attention without ostentation — the hallmark of enduring Swiss design.

This Constellation is powered by an Omega Co-Axial Master Chronometer movement, certified by METAS to resist magnetic fields of up to 15,000 gauss and to deliver exceptional chronometric precision. The Co-Axial escapement reduces friction for improved long-term reliability compared to a traditional lever escapement.

3. What is the case size of reference 131.55.29.20.55.003?

4. Is the Omega Constellation 131.55.29.20.55.003 suitable for everyday wear?
Yes — while the all-Moonshine Gold construction and diamond dial give it clear dress-watch credentials, the Master Chronometer movement's magnetic resistance and durability make it a capable daily companion. It is ideally suited for anyone seeking a luxury watch that performs as well as it presents.

5. What is Moonshine Gold and how does it differ from regular yellow gold?
Moonshine Gold is Omega's proprietary 18-karat gold alloy, developed to exhibit a slightly paler, warmer tone compared to conventional yellow gold while offering superior resistance to fading over time. This exclusive material ensures the watch retains its distinctive warm luster far longer than a standard gold alloy would.
