Omega Seamaster Aqua Terra 150M Co-Axial Master Chronometer Ladies 38mm Sedna Gold Diamond Bezel Diamond Pave Ruby Index Dial Alligator Leather Strap 220.58.38.20.99.001 - BRAND NEW

The Omega Seamaster Aqua Terra 150M has long occupied a singular position in the world of luxury sport watches, blending genuine aquatic capability with the refined sensibilities of a dress timepiece. Within this storied line, the ladies 38mm references in precious metals represent its most elevated expression—pieces conceived not merely as instruments of timekeeping but as wearable works of art. Reference 220.58.38.20.99.001 sits at the very apex of that vision, uniting Omega's proprietary Sedna Gold case construction with gem-setting artistry of the highest order.

Sedna Gold is Omega's own patented rose gold alloy, developed in-house to retain its warm, rich hue far longer than conventional 18k rose gold. The precise metallurgical composition—incorporating gold, copper, and palladium—gives the case of this Aqua Terra its distinctive warm blush tone while ensuring lasting color stability on the wrist. At 38mm the case strikes an ideal balance, substantial enough to project genuine presence yet supremely elegant on a range of wrist sizes.

The dial of reference 220.58.38.20.99.001 is nothing short of spectacular. A full diamond pavé surface is set stone by stone by Omega's craftspeople, creating an unbroken field of brilliance that catches light from every angle. Ruby indexes punctuate the dial with deep crimson accents, providing both functional hour markers and a vivid chromatic contrast against the white scintillation of the diamonds. The bezel, too, is entirely diamond-set, framing the dial with a continuous band of precisely matched brilliant-cut stones that amplify the overall radiance of the watch.

At the heart of this timepiece beats Omega's Co-Axial Master Chronometer movement, the brand's most advanced and rigorously certified caliber standard. Master Chronometer certification, awarded by the Swiss Federal Institute of Metrology (METAS), demands that a movement pass eight stringent tests covering precision, magnetic resistance, and performance in multiple positions—guaranteeing accuracy of 0 to +5 seconds per day. The Co-Axial escapement, an Omega hallmark, dramatically reduces friction and the need for lubrication, contributing to long-term reliability and reduced service intervals. An alligator leather strap completes the ensemble, its supple texture and elegant scale pattern offering a comfortable, refined wearing experience befitting the precious metal case it accompanies.
