Omega Seamaster Aqua Terra 150M Co-Axial Master Chronometer Ladies 38mm Sedna Gold Diamonds White Dial Diamond Set Index Alligator Leather Strap 220.58.38.20.55.001 - BRAND NEW

The Omega Seamaster Aqua Terra 150M is one of the most celebrated lines in contemporary Swiss watchmaking, tracing its roots to Omega's storied Seamaster heritage that stretches back to 1948. Designed to bridge the gap between a true diver's watch and a refined dress timepiece, the Aqua Terra 150M is equally at home in a boardroom as it is near the water. The "150M" designation underscores the collection's water-resistant credentials, while the clean, open-dial architecture and iconic teak-pattern motif have made it a perennial favourite among discerning collectors worldwide. Reference 220.58.38.20.55.001 represents the collection's most luxurious expression, elevating the Aqua Terra into genuine haute horology territory.

At the heart of this reference is the choice of Sedna Gold for the 38mm case. Sedna Gold is Omega's proprietary 18-karat rose-gold alloy, developed in-house and trademarked to ensure a warm, richly saturated rose hue that resists fading and discolouration far better than conventional rose gold. The result is a case that glows with an enduring warmth, catching the light in a way that standard precious metals simply cannot replicate. Paired with the smooth, supple texture of a fine alligator leather strap, the wrist presence is simultaneously sporty and deeply luxurious.

The dial of reference 220.58.38.20.55.001 is a study in brilliant contrasts: a white ground set with diamonds at the hour indices radiates understated glamour, while a diamond-set bezel frames the dial with a continuous ring of scintillating stones. Every diamond is selected and set to Omega's exacting standards, ensuring uniformity of brilliance and the kind of finishing that befits a brand that has supplied timepieces to NASA astronauts and Olympic Games athletes alike. The overall effect is one of jewellery-grade splendour without sacrificing legibility or the sporty DNA that defines the Aqua Terra line.

Powering this exceptional watch is Omega's Co-Axial Master Chronometer movement, the brand's most advanced movement architecture. The Co-Axial escapement, developed by master watchmaker George Daniels and adopted by Omega, dramatically reduces friction compared with a traditional lever escapement, extending service intervals and improving long-term accuracy. Master Chronometer certification—awarded by the Swiss Federal Institute of Metrology (METAS)—subjects the movement to eight stringent tests, including resistance to magnetic fields of 15,000 gauss, guaranteeing performance standards that surpass the traditional COSC chronometer benchmark. Buyers can wear this watch with complete confidence in its precision and reliability.

With a 38mm case diameter, this Aqua Terra occupies a versatile sweet spot: large enough to make a statement on the wrist yet refined enough to complement both casual and formal attire. The alligator leather strap adds a couture sensibility, ensuring that the watch transitions seamlessly from daytime elegance to evening occasions. Whether purchased as a personal indulgence, a milestone gift, or a considered addition to a growing collection, reference 220.58.38.20.55.001 is a watch that will command attention for decades.
