The Omega Constellation reference 123.20.31.20.55.003 pairs a round 31mm case with a fixed bezel crafted from stainless steel and 18kt rose gold, its surface dressed with Roman numerals that serve as second markers. Scratch-resistant sapphire crystal protects the iridescent mother of pearl dial beneath, where 11 diamond hour markers and rose gold-tone hands keep the time alongside a date function.
Power comes from an automatic movement, with time read via hour, minute, second, and date indications. The pull/push crown makes setting straightforward, and the bracelet closes with a folding clasp for secure, comfortable wear.
Swiss Made and presented complete with its original box and papers, this Constellation is a considered choice for those drawn to the enduring combination of rose gold warmth against the cooler tone of steel.
